It is the most modern and helpful tool to people. The Stock is an aspect of life that IT has been applied widely. This has brought many significant successes in order to promote the development of the stock market. Hanoi Security Trading Center (HASTC) is a special financial one of State Security Commission which was set up in 1998 and situated in Hanoi – Vietnam. During 8 year’s development, HASTC has overcome the difficult stages. However, it has created a sustainable belief in everyone about Vietnamese stock market. Realizing the important role of developing securities in Vietnamese finance and studying about it for a long time, we see that there is still a part in security that IT has not yet exploited. That is Management for registration and information of companies listed in the stock market. At present, the traditional management model with documents, staff have to work with paper, is quite well-liked or popular in Management for registration and information of companies listed at the center. However, this model now has met some problems such as: - Waste of time - Need a lot of supervising staff - Waste a large amount of money for printing documents and writing papers - Do not avoid negative actions in management - Decrease importunacy procedure - And other unexpected problems… Basing upon the current IT infrastructure of HASTC, as well as conforming to the rules and principles of a management procedure for registration and information at the center, we decide to build a system in order to deal with the drawbacks of such traditional exam model. It is called: System for Registration and Supervision of securities listing company in HASTC. Its abbreviation is: SLIMS – Stock Listing Company Management System. HUT – Genetic computer school – Group 7 Page 4 Website: http://www.docs.vn Email : lienhe@docs.vn Tel (: 0918.775.368 The system allows users at different level to manage user’s account and generate reports. Employee is able to manage initial information, periodic information and extraordinary information as well as calculate daily transaction of a company listed at the center. Some companies are granted to control for an employee by an administrator. All of the above tasks are carried out through LAN to help the management become easier and more convenient The main purpose of the system is to serve HASTC in management for registration and information of company listed at the center and assisting them for auctioning and bidding financial assets such as: bonds, stocks … We hope that this system can increase the quality of operation as well as partly contribute to the development of the center in particular and generally in Vietnamese stock market. 1.2 BACKGROUND  What is Stock Listing Company Management System? Differ from traditional Stock Listing Company Management System, SLIMS enables employee from working with computer to use it proficiently in management. Furthermore, employee will view information, edit listed company information, and give their opinions aiming to develop the management of center better and better. In addition, the system also support administrator effectively in performing tasks such as: managing employee, backing up or restoring data. The system works with users in the faster, most effective and most friendly way.  What are the purposes of Stock Listing Company Management System? The main purpose of the is to serve HASTC in managing registration of listing companies in centralized way, also in supplying necessary information about listing companies to employee and involved people. We hope that this system can increase the quality as well as effect of management, partly contribute to the development of stock market at the center in particular and generally in Vietnam. The professional knowledge of management involved: - Managing registration for listing company. - Managing additional adjustments after giving listing company’s permission. HUT – Genetic computer school – Group 7 Page 5 Website: http://www.docs.vn Email : lienhe@docs.vn Tel (: 0918.775.368 - Supervising listing companies. - Managing audit company and auditor agreement. This system will be run on LAN of Department for Transaction Management. It also allows users at different level to manage user account, generate reports, create and adjust information of listing companies. The outstanding advantage of the system is high security. The system is based upon a principle: just an employee creates data then be able to edit data. In addition, SLIMS also has other advantages in comparing with the traditional measure such as: save time, low cost, are not waste of human resource, etc…Data of system are managed centrally by database management system SQL Server 2000. Data are structured and unstructured (text file). Because of the preeminent features that SLIMS provides, we hope that the system will give users and administrators satisfactions when they use it. 1.3 EXISTING SYSTEM AND SLIMS 1.3.1 Current System At present, with the traditional management model, all the tasks of Department for Transaction Management performed with papers manually, from preparing and executing jobs must be done for listing when it is ended. As listing License is accepted, an employee is taken the management of some specific companies by manager. If this employee is out of work or busy, company management is interrupted. It takes a lot of time to give this work to another, as well as it takes a lot of time for another to review. This management is ineffective and waste amount of money for printing data. Question Paper Our Stock Listing Company Management System seeks the answer to the following questions: 1. What are the objects and applying areas of the new program? 2. What ideas originated from employee/managers? 3. How are forms represented? 4. For what does the system need to provide? HUT – Genetic computer school – Group 7 Page 6 Website: http://www.docs.vn Email : lienhe@docs.vn Tel (: 0918.775.368 5. How do employee/managers solve problems before the introduction of the program? 6. Where is data taken from? Magnetic tape/Compact Disk/Magnetic Compact Disk/Hard Disk/COM port/Outside System 7. How often is data exchanged? Daily/Weekly/Fortnight/Monthly/Annually 8. How many people will access the system? 9. Who are allowed to modify input data? 10. How is data input? 11. Which information of employee/managers must you input? 12. Is the current service economic and does it meet the employee’s needs? 13. Any trouble arises from using it? 14. Is there any Stock Listing Company Management System used in Vietnamese stock market? 15. Is the infrastructure good enough for implementing the system? 16. What are the benefits of Stock Listing Company Management System compared to conventional method of assessment? 17. Does the use of Stock Listing Company Management System require professional knowledge? 18. What are the feedbacks and recommendations for the system? 19. How much does it cost for a system like Stock Listing Company Management System? 20. Does the administrator of the Stock Listing Company Management System need to have professional knowledge? 1.3.2 SLIMS In order to overcome the disadvantages of traditional model, we develop SLIMS, which is applied to Department for Transaction Management at HASTC. This system will be run on LAN of Department for Transaction Management. It also allows users at different level to manage user account, generate reports, create and adjust information of listing companies. The outstanding advantage of the system is high security. The HUT – Genetic computer school – Group 7 Page 7 Website: http://www.docs.vn Email : lienhe@docs.vn Tel (: 0918.775.368 system is based upon a principle: just an employee creates data then be able to edit data. In addition, SLIMS also has other advantages in comparing with the traditional measure such as: save time, low cost, are not waste of human resource, etc…Data of system are managed centrally by database management system SQL Server 2000. Data are structured and unstructured (text file). And the printer allows the user store documents. 1.4 PROJECT SCOPE Based on discussed points, SLIMS is aimed to provide a system which can satisfy the needs of users (including manager and employees) at Department for Transaction Management of Hanoi Securities Trading Center. For the specific characteristics of Department for Transaction Management, the system ensures the ability of managing user account, calculating daily transactions, managing all general as well as extraordinary information of listing company and generating reports. Together with the above main functions of the system, it extends some functions help users easily access information of a company and total volume of daily transactions.

Infrastructure HUT – Genetic computer school – Group 7 Page 8 Website: http://www.docs.vn Email : lienhe@docs.vn Tel (: 0918.775.368 To operate completely the system, we need a large amount of interconnected PCs that forming a networked PC area (LAN). At present, the centre has a room with 10 PCs. With the current PCs, that is enough for processing information of listing companies at the centre. Especially, we need at least one Server PC with the very high configuration. The advantage of the client/server architecture is that the client and server machines work together to accomplish the processing of the application being used. The processing capacity is improved and efficiently utilized. The clients are optimized for user interaction. Meanwhile, centralized, multi-user functionalities are performed by the servers. The database can be stored and backup in multiple servers for data safety HUT – Genetic computer school – Group 7 Page 9 Website: http://www.docs.vn Email : lienhe@docs.vn Tel (: 0918.775.368 CHAPTER 2 - DEVELOPING TOOLS 2.1 MODELING LANGUAGE 2.1.1 Unified Modeling Language (UML) HUT – Genetic computer school – Group 7 Page 10 [...]...
