Video Club Database Project Essay Example
Video Club Database Project Essay Oceanic Video Club is a private business, run by its owner Mr. Michael Coleman. Oceanic is a video club which is in the selling of films. The owner Mr. Michael has built up a large customer base and this is increasing year by year. The business is going well as the amount of clients is increasing. As Mr. Michael hold a list of customers on a paper-based filling system, so Mr. Michael does not worry about the client as they are being informed automatically. Consequently, he has decided to make an investment on a comprehensive customer information system so that he can hold details on his customers, who have been purchasing films in the last few years and now. Also to take their opinions about the video club so that he can offer his customers a better service.. An interview with Mr. Michael was arranged.

The precise objectives of the new system. The method currently used to record data. The information that needs to be kept on each customer. Any hardware or software constraints. The required output. The volume of data to be processed. The problems with the new and manual system. 1. How many employees do you have? 2. Do you sell on credit or cash? 3. Do you have any problems with debtors? 4. What are the expenses which you make each year? 5. What types of music do you sell? 6. Do you own or rent this place? 7. What problems do you get with the manual system? 8. How much money are you ready to invest in the computerization? An interview with Mr. Michael was arranged and a lists of topics for discussion drawn up prior to the interview. These included: Self: How many copies do you have in your stock? Mr. Michael: I have about 1500 copies. Self: Do you sell on credit or cash? Mr. Michael: I work with both systems. Self: Do you have any problems with debtors? Mr. Michael: Yes as it is usually the case everywhere. Self: What are the expenses which you make each year? Mr. Michael: When films are damaged I incurred a loss. Self: What types of films do you sells? Mr. Michael: I sell all types of films. Self: Do you own or rent this place? Mr. I own this place. Self: What problems do you get with the manual system? Mr. Michael It is time consuming to fill records on paper and sometimes important documents are loss. Self: How much are you ready to invest in the computerization? Mr. Michael would invest about Rs30 000 in the new system. Summary of the interview A lots of problems with the new system has been revealed during the interviews, and the new objectives recommended was done but it was time consuming to take data from the old paper-based system and put it in the new system as their was more than 300 regular customer in the old system and with 50 new customers being added every year. Problems to current system 1. Loss of records. Solution A. Use of a cupboard. Advantage All the records will be arranged in the cupboard drawers. Disadvantage It takes a lot of place Solution B. Used of a computerised database. Advantage Access to the information is rapid and there is less likelihood of the data becoming lost. Disadvantage Training is needed to use the system and this takes time and cost a lot of money. 2. Contacting customers about new items. Solution A. By sending letter to customers. The objectives may be stated in both quantitative and qualitative terms. 1. It should take less than 30 seconds to establish whether a customer is already on file and to fill in new films records. 2. It should be possible to go directly to the main menu screen to the entry of a transaction, without having to re-enter the customers name, etc 3. Data entry should be as fast and easy as possible, particularly as there are several hundred existing customers and music to be entered when the system is first installed. 4. It should take less than one minute to trace music for a customer. 5. The new system is required to provide the following information; a) A list of all available music. b) A list of all customers. 6. The main menu should be displayed automatically when the database is loaded, and the whole system should be menu-driven. The following is the data flow of the proposed system. The system to be developed is a customer information system, and is intended to enhance rather than replace the current system of recording music and customers records. If this proves successful, it will be possible at a future date to replace the current methods of recording records so that the details are typed directly into the computer and the required copies printed out. This could then be extended to link into a computerized accounts system. Software The customer has requested that the system be developed using Ms Access, so useless a good reason transpired for using an alternative program or package Ms Access will be the first choice of software. Hardware In order to run Ms Access and be able to perform a mail merge using word, a PC 486 or Pentium with a minimum of 8 MB, and preferably 16 MB, will be required. A fast processor such as a P4 will be needed if the system is not going to appear slow in switching between screens. Mr. Ah-Young is familiar with word and has a good keyboard skill, so should have no problem entering data and learning how to use the system. He would like to improve his knowledge of basic so that he can in the future perform new queries and reports as the need arises. A database package will be ideal for implementing the system for Power Music Shop, and as Mr. Ah-Young has requested that it should be done in Ms Access. This is the package that must be used. It would probably be possible to implement the system using Ms Access or another programming language but it would take longer time and would involve the owner having to buy more software which is not really necessary, as Ms Access has all the capabilities required. I already have some experience of Ms Access and it is available both at home and at college for development. Using this package it will be possible to * Set up the necessary tables and relationships. * Produced customized input screens, using Ms Access to automate data entry wherever possible and to perform various validations. * Use Ms Access modules to enable fast searches for a particular Customer and past stay. * Design reports as needed. The database contains two entities, which are CUSTOMER and MUSIC. Tables will be created for each of the entities. Tables will be created for each of these entities. The tables will contain the following data. Attribute Name Data type and length Validation Film code Text (4) Unique primary key Title Text (50) Actor Text (50) Actress Text (50) Type Text (20) Number of copies Numeric (2) Duration Text (6) Attribute Name Data type and length Validation Code Text (4) Unique primary key Name Text (20) Other Names Text (20) Date Of Birth Text (8) Sex Text (6) Address Text (50) Tel number Text (7) ID Card Number Text (16) Two data entry form are needed. This form will be used for several purposes so it needs facilities to * Check to see whether a Customer is already on the database. * Add a new Customer. * Look though all the existing records for the current Customer and bring up more details if necessary. The Customer details form will be as shown on the next page. This form will be used for several purposes so it needs facilities to * Check to see whether music is already on the database. * Add a new music * Look though all the existing records for the current music and bring up more details if necessary. The music details form will be as shown on the next page. Customer File FILM File The format of all the reports will be similar. The layout of the Customer report is shown below. The menu structure is as follows: A password will be attached to the database so that it is only accessible to someone who knows the password. Different access levels are not needed as Mr. Pascal is the only person who will be using the database. 9. Test Strategy The test strategy will include five different types of testing as described below: LOGICAL TESTING This will be used to test every aspect of each form, report and query as soon as it is implemented, using valid, invalid and extreme data. Test data will be added to test each code module and results compared with expected results. Sufficient data will be added to ensure that there is at least one customer in each category. The test data that will be added initially is shown in Appendix. Subsequent test will often involve adding new data, which will then be deleted when the test works satisfactorily. FUNCTIONAL TESTING Each menu item will be tested in turn to ensure that no function has been missed out. SYSTEM TESTING When the system is complete, the whole range of tests will be carried out again to ensure that no errors have been introduced. RECOVERY TESTING The computer will be re-booted while the database is open to ensure that data is not lost or corrupted in the event of a power of a power failure. ACCEPTANCE TESTING The user will then be involved and asked to test all the capabilities of the program to ensure that all request functions are presented and working in the manner expected. This testing may result in further refinements. SECTION 3 TESTING TEST PLAN Module: Password Menu TEST NO. TEST EXPECTED RESULT REMARKS 1 Insert correct password and click on Login Main Menu should appear on the screen. OK 2 Insert incorrect password and click on Login A message saying wrong password should appear on the screen. OK Module: Main Menu TEST NO.

Must be able to delete a record. OK 4 Click on Back to Main Menu command button. Main Menu must appear on the screen. OK SECTION 4 SYSTEM MAINTENANCE 1. SYSTEM OVERVIEW This Customer information system is designed to keep records of Customer profiles and their past purchases. It is designed to run alongside the current manual system of recording purchases, rather than replacing it. The computer will be in the reception and the owner can use it to check whether a customer who comes in is already on the database, or to check on past purchases. New data will be added to the database at a convenient time, possibly at the end of the week. The procedure that the user will fellow is described in the design section. 2. TABLES AND RELATIONSHIPS Tables and relationships were set up as specified in the design section. 3. FORMS The menu structure was set up as specified in the design section. Forms were used as follows: Main Menu This is specified as the start-up form and loads automatically when database is opened. All buttons either opening other form or reports, or quitting the database, were placed using wizards. Report Menu All buttons placed using wizards. Maximise macro runs on opening form. Input Forms The Customer details form has a combo box displaying Customer codes so that the user can look up the record for any Customer. The record source for this box is the database. 4. REPORTS These are as described in the user manual. All reports were created using wizards and then tailored to produce a more appropriate layout. SECTION 5 USER DOCUMENTATION Initial set up Password Menu The Password menu is automatically started when the database is loaded. The password is case sensitive but it will only accept OCEANIC. Main Menu The Main Menu will automatically appear when you enter the password. Film File Add a new record In order to add a new record, click on Add new and after adding all the information, click on Save Record.

View a report In order to view a report, click on Customer Report. SECTION 6 APPRAISAL The system has been completed and installed on the users PC. It was completed in the manner originally designed and agreed with the user, and is straightforward to use. Referring to the original objectives listed in the Analysis section: 1. It should take less than 30 seconds to establish whether a film or a customer is already in the database. 2. It should be possible to go directly from the film files screen to the entry of a new film. 3. Data entry is as fast and easy as possible. 4. The new system provides the following information. a) List of all films. b) List of all customers. 5. The main menu should be displayed automatically when the program is loaded and the whole system should be menu driven 6. Mr. Pascal had some problems initially with data entry, confusing Items and customers, as this aspect works a little differently from the manual system. However he has now entered data for over 100 items and has no problems to report. 7. All reports are implemented as specified. 8. The menus work as planned.

101 Diversity and Showing Professor Ramos Blog
101 Diversity and Showing Quick Write Quick Write Diversity: the condition of having or being composed of differing elements; especially the inclusion of different types of people (such as people of different races or cultures) in a group or organization. How has diversity affected you? I take your point The concepts we will be studying about writing also pertain to oral conversations. The templates from Chapter 12 show how to frame a comment in response to a discussion or argument. How to change a topic as well as how to be clear when speaking and writing. Framing a Discussion We will have many different conversations in this class. Keep the idea of framing in mind to help you make your point clear and to help us understand your point. We need context to make a point. President Obama Commencement Speech at Howard University President Obama makes many points in this speech. Take a few minutes and write down the important points you think should be discussed. Types of Diversity Types of diversity, include, but are not limited to: race, gender, ethnicity, sexual orientation, age, socioeconomic status, religion, and disability. Journals Journals are easy points to get, that are meant to help you in this class. If you do them, or attempt them, you earn the points. The first two journals asks that you answer some questions. We will continue to build on skills and incorporate them into the journals. Starting next week, you will be writing summaries of the readings. American Greatness Leaves of Grassà is Walt Whitmanââ¬â¢s book of poetry, first published in 1855. He published six editions during his lifetime. He revised, expanded, and tinkered with the book to reflect the changes taking place in American culture and himself. The Americans of all nations at any time upon the earth have probably the fullest poetical nature. The United States themselves are essentially the greatest poem (1009). Walt Whitman is the great visionary. He was the first person to say America is the greatest nation. Here is not merely a nation but a teeming nation of nations (1010). What makes us great is that we are made up of immigrants. We are a growing and evolving nation. This is what makes us the greatest nation. . . . but the genius of the United States is not best or most in its executives or legislatures, not in its ambassadors or authors or colleges or churches or parlors, nor even in its newspapers or inventors . . . but always most in the common people (1010). He continues and argues that he could only write this because he is an American. Lyndon B. Johnson John F. Kennedy ââ¬Å"They Sayâ⬠Chapter 1 argues that good academic writing responds to what others are saying.

Globalisation Essay Example | Topics and Well Written Essays - 1500 words
Globalisation - Essay Example The opportunity hidden in globalisation has led to the development of globalisation. The first opportunity that globalisation provides us free trade facility and its resultant effect on the global economy (Milward, 2003, p.10). Free trade would lead to an increase in the trade which would increase the financial flows between various economies. Globalisation would result in an increase in free trade which would increase lateral financial flows and the redistributed capital would help to pull up the impoverished countries from their financial woes. The second opportunity provided by globalisation in development of a transnational framework which would help in the development of a smooth trade system. The origin of internationalisation of industry and commerce can derived from both macroeconomic approach and micro economic approach. The macro economics approach consists of expansion of firms' activities beyond the countries where they have their registered offices can be explained with the help of international division of labour theory and the huge circuits of capital. A micro economic approach deals with the theory of product life cycle and Dunning Eclectic Paradigm (Hansen, 2009, p.3). Nationââ¬â¢s now have less control over their individual industries and economies so the global network is assuming more control over the markets around the world. The global network must keep in mind the welfare of both the global community and the individual nations. Globalisation refers to the intensification of the relationship between various countries which has been set with the help of internationalisation. Foreign Direct Investment involves transfer of intangible or tangible assets from one country to another in order to generate wealth in that country through total or partial control over their assets (Sornarajah, 2010, p.8). Foreign Direct Investment is one of the key elements of the rapidly evolving international economy. This is also referred as globalisation. Fore ign Direct Investment helps to create a stable, long lasting and direct link between economies. Under a correct environmental policy the Foreign Direct Investment can serve as an important tool for the purpose of development of local enterprise. Foreign Direct Investment helps in economic development of the developing countries. The level of economic development is higher in the case of FDI than in licensing, franchising or exporting (Jones and Wren, 2006, p.9). Foreign Direct Investment infers when a group of companies or individuals of one country buy assets of another country (OECD, 2009, p.14). The acquisition of the assets happen when foreign companies or individuals to control the means of production as well as distribution. Example- a company in US can purchase a production facility in Australia. By acquiring the production facility in Australia, the corporation can control the entire production process from US. This would help to ensure the quality of the product. A foreign direct investor can have a varying amount of stake in the company invested by him. FDI indicates at least 10% ownership in a company which helps the investor to control the daily affairs of the company as compared to licensing, export and franchising where very control can be exerted (Cohen, 2007, p.38). Some countries have a cap on the equity investment in their country. FDI helps in generating economic growth for a country so it preferred over licensing, franchising and exporting (Neuhaus, 2006, p.42). People who buy stocks in the company own a part of the company and have the ability to control the affairs of the co

Nucleons Stocks in the Stock Market Essay Example | Topics and Well Written Essays - 1250 words
Nucleons Stocks in the Stock Market - Essay Example In this way, the investors in the stock market will automatically become owners or stockholders of Nucleon. Second, Nucleon can generate cash from loans. This large ââ¬âsum debt will create a creditor-debtor relationship. The debtor will be Nucleon whereas the creditor will be the company or individual that lends money to Nucleon. The following paragraphs explain why the pilot in-house capital budgeting is the best investment choice in this case study(Louderback, 326). à I recommend that the company pursue its plans to set up its own pilot plant. This is the best choice of the three possible alternatives. For, the second alternative is not a good choice because the third party that will be contracted by Nucleon may not have the capacity or the money to produce the CRP -1 gene clone. Furthermore, the most important factor in not choosing alternative 2 is confidentiality. Meaning, there is a possibility, even a small one, that the subcontracted third party will abuse its responsibility not to divulge or abuse the confidential formula or processes in manufacturing the CRP -1 gene clone(Needles, 367). à In terms of risk, the third party may then set up its own marketing department and to sell the CRP -1 gene clones without reporting such sales to Nucleon and pocket the profits themselves. Further, the third party will then eat away or pirate many of CRP - gene clone clients. As for the other choice which is to license manufacturing and marketing rights to another biotechnology group, it is worst than the subcontract choice here. For, the chosen biotechnology group could then learn the secret formula and confidential processes of mass producing CRP -1 gene clones. In fact, the upfront cash that the Nucleon will receive in exchange for the secret processes and formulas given to the third party to produce the CRP -1 gene clone is only a small matter.

Optical Sensing of Molecular Oxygen
Optical Sensing of Molecular Oxygen Optical sensing of molecular oxygen is gaining approval in many areas, such as biological research,1 clinical and medical applications,2 process control in the chemical industry3 and in food4 and pharmaceutical5 packaging, to name just a few. The best sensor should be stable, robust, easy-to-use and not prone to electrical interferences.6, 7 Quenched-luminescence oxygen sensing has attracted a great deal of attention and scientific endeavor in recent years. In particular, solid-state sensors holds many advantages over traditional oxygen sensing techniques like Clarke-type electrodes8 as they fulfil the above requirements and additionally have a reversible response to oxygen and can measure oxygen non-invasively without being put in contact with the sample.9 Solid-state sensors usually consist of an indicator dye encapsulated within an oxygen permeable polymer matrix.6, 10 The properties of the encapsulation matrix used, for instance its dye compatibility, oxygen permeability, wettability and mechanical properties, determine the final sensor operating parameters such as sensitivity and response time.6 The selectivity of the sensor is dependent on the indicating dye used. Compounds such as ruthenium and iridium compounds have been investigated,11, 12 however oxygen sensors based on platinum13 and palladium14, 15 metallopor phyrins has been the main focus of many research groups in the past.13 Polymers with high and moderate oxygen permeability have been used as encapsulation matrices, for instance, polystyrene, placticized polyvinylchloride, polydimethylsiloxane and fluorinated polymers.6 Many sensors require an additional support material due to the thin-film nature of many dye encapsulation matrices. The support material improves the mechanical properties of the sensor and aids handling and optical measurements.16 These oxygen sensors are usually produced by solution-based techniques by which the polymer is dried from an organic solvent cocktail,17 or by polymerization or curing of liquid precursors.18 Other dye incorporation methods include adsorption,19 covalent binding,20 solvent crazing,21 and polymer swelling methods (REF US). However, as previously shown in a study (REF US), some microporous membranes materials can be used as stand-alone sensor materials as they have sufficient thickness and light-scattering properties in addition to good mechanical properties and reasonably fast response times to oxygen in the gas phase. Although used in many applications (see above), many current sensor materials, fabrication techniques and polymeric matrixes are unsuited to large-scale applications such as packaging. A sensor for packaging should exhibit high robustness and reproducibility between batches, low cost (less than 1c per cm3)6 and be easily incorporated into existing packaging processes. Care should be taken when developing such sensors to limit the number of ingredients in order to limit their overall production costs.22 To be suitable for food and pharmaceutical packaging applications specifically, the sensor should be non-toxic,23 easily incorporated into the packaging and provide an adequate shelf-life for the required application.9 The sensors must also be capable of being mass produced in a continuous basis. Polyolefins such as polypropylene (PP) and polyethylene (PE) are common polymers which represent over half the total polymers produced in the world.24 Although the mechanical and gas-permeability properties of PP and PE are capable of oxygen sensing,25 there are obstacles regarding insolubility in common organic solvents and incompatibility with many oxygen sensing dyes. However, some PE and PP-based oxygen sensors have been created by solvent-crazing,25 hot polymer extrusion26 and swelling methods (REF US) that show potential for packaging applications. Of late, non-woven polyolefin materials have been developed for a range of industrial applications including textiles, membranes, filtration systems27 and charge separators in Li-ion batteries.28 These materials are cost-effective, have suitable chemical and thermal stability, gas permeability, uniformity and thicknesses between 20-150 microns.27, 29 In addition, they are micro-porous, light-scattering and have a large surface area.28-31 These membranes can also be modified to improve wettability by grafting the surface of the polymer with hydrophilic monofibres.32, 33 In this study, we evaluated two types of grafted PP as a matrix for fabrication of O2 sensors. The polymer membranes selected for this study consists of PP monofibres bound together by the wetlaid and spunbond method into flat flexible sheets. They possess a high surface area, good mechanical and chemical resistance and light-scattering properties. In addition the membranes have been grafted with a hydrophilic surface in order to improve wettability which is beneficial for opto-chemical sensing applications. Therefore, a simple spotting method can be used to incorporate the dye into the membrane. The advantage of this is the membrane doesnââ¬â¢t need an extra support matrix and the spotting method can be carried out with readily available commercial equipment when it progresses to upscaling. In addition, due to the size of the discrete spots, consumption of solvents and substrate material is kept to a minimum which lowers production cost. 1.D. B. Papkovsky and R. I.

Als Reflective Thinking Essay
Reflective Thanking Essay I am a good leader. One who takes initiative in getting the tasks completed while keeping the morale tempo up and making it a good experience to all. Iââ¬â¢m one who will take criticism and can listen even though I may not like what Iââ¬â¢m hearing, but in turn apply those criticisms and make a better me. Simply being said, I like to take charge, inspire those around me, complete the mission and wait for the next challenge.Thank my mother for who I am, she inspired the person I am today. I was raised in a very strict environment where there were expectations. Rules, responsibilities, honesty and involvement were all considered necessities. I was introduced to community service when I was 5 years old when I was a Girl Scout. Then later when my late father and I would participate in an annual cancer awareness marathon it was a beginning point for me.So from then on there the feeling of accomplishment to help others inspired me. Iââ¬â¢m one who wants p eople to come to be with their troubles so I can help, Iââ¬â¢m the one who wants to reach out and touch others and just inspire. Itââ¬â¢s easy for me to say that Iââ¬â¢m a participative leader. I want to get involved with my fellow wingmen and know theyââ¬â¢re comfortable coming to me with any issue they may have. Iââ¬â¢m one who strives towards a positive workplace.I like to work next to my fellow crew chiefs and solve problems. I treat others with mutual respect on the job. I am open-minded to my fellow airmen and respect their thoughts and opinions, but understand that the final decision rest in my hands on any given situation. Based on the decision making process, I feel the type of NCO (non-commissioned officer), Iââ¬â¢ll become will be similar to the image I uphold now will make people work for the correct answer or the right thing to do.Though I understand that this technique will not work with all, but itââ¬â¢s a starting point for me to evaluate an indi vidual. One of my strengths is that Iââ¬â¢m very smart. Iââ¬â¢m very accepting to challenges. Another one of my better traits is that Iââ¬â¢m a very good listener. I can influence new views on issues and provide help to a better outcome when the issue is good or even bad. I just put myself is their position and think ââ¬Å"what would Melissa do? ââ¬
