HOME WORK REQUIREMENT ENGINEERING Name: Le Van Hao Class: K15CMUTPM I. Introduction: Documentation was conducted to present an overview about the library system of the QuangNam University of Pedagogical and the mode of operation is happening and the problems is happening in order to make a new plan to improve the system. Project Name: upgrade and development of university library systems to borrowing books. Proposed systems: apply technology to the library system to increase effectiveness in managing loan books, return books and to integrate website in the system. II. Referenced: The system documentation for new users of software. For questions or encounter errors that users can also refer to the instructions online through the hotline. III. Current system and situation: 1. Background, Objectives, and Scope: a. Background: Nowaday the most libraries are return and borrowed books like a manual type , that's mean if you want to read and borrow book , you would talked with the librarian. Nowaday , application of technology to serve readers new project to upgrade the system, reduction in employment and improve service quality. b. Objectives: The system allows managers can update information entered all of these books have you read in the libraries to be searchable in a convenient, but also integrates Web browser, allowing users to place and loans borrow books in the library online. The system has divided section dedicated to a manager and you are reading. You can only read the search and asked to borrow library books or place, managers are allowed to change add a library book information. During use the user may require software developers to complete more of the functionality available in the system. c. Scope: Library system at the DuyTan University. 2. Operational policies and constraints: a. Policies: Reader must register membership to borrowing books. When readers borrow or return books must show their membership card. b. Constraints: Return and borrowed books like a manual type. Readers can not borrow or return books after hours. 3. Description of current system or situation: a.

Assist in the library inventory a simple and clear. c. The operational environment and its characteristics Good material facilities good , computer system connection with an internet Human resources are firmly professionals and capable of working in high pressure environment. Procedures for operating the system: the library staff must have an account of system to intervene and perform tasks on the computer system such as borrowing books, renewing books, locking account… Readers work with library staff to borrow books and return books. d. Major system components and the interconnection among those components: There are three computer tasks is managing the library.

IV. Justification and description of changes: Because the system library don’t apply technology to the library system to increase effectiveness in managing loan books, return books and to integrate website in the system. So the software system will hepl in job manage library become simpler and more efficient. 1. Justification of changes: The system sofware will digitization of all the information about books, textbooks, materials. Simultaneously the system software will provide manager the ability manage all information of the book in library, and all reader have been borrowed library the books. 2. Description of disired changes The system software will provide the user such software based on their business processes to increase work efficiency and save time and manpower. Capability changes: System software will be compeleted in six months. System processing changes: From model to handle manually processed by computer. Interface changes: From paper processing to handle the computer screen. Personnel changes: Only a few managers are able to manage the entire library system. 3. Priorities among changes High priority: Capability changes, system processing changes, personnel changes, environment changes, operational changes. Normal priority: Support changes, interface changes, others changes… 4. Changes Considered But Not Included: Comments and rating below book. News about book. Background: library System is identified as a combination system. Combination systems have independent member libraries and also offer direct services to the public users. Objectives: • Library Staff and Student. Scope: • Duy Tan University. V. Proposed system or situation: 1. Background, Objectives, and Scope: 2.

Bandwidth: can reach about 2GB per day. Frequency: can response for about 100 page views per second. i. Quality attributes: High Availability Correctness Easy to Expand High Flexibility High Interoperability Easy to Maintenance High Reliability Easy to install and use Cheap. j. Provisions for safety, security, privacy, integrity, and continuity of operations in emergencies that exert influence on the operation or operational environment of the current system: When the System have some problem, there’s a sub-system replace immediately The System will be back up every time and everywhere. The System will fixing as soon as possible and working normally after that. 4. Proposed Modes of Operation. 5. Anticipated Users and Stakeholders. 6. Proposed Support Environment. VI.
