Case Study: Library System 1. Problem Statement The Library System is a web-based application used to automate a library. It allows the librarian to maintain the information about books, magazines and CDs. It also allows the librarian to maintain the information about its users. It provides the facilities such as search for items, browse, checkout items, return items, make reservation, remove reservation etc. to its users. To borrow the items from the library, the users must register in the system. The search option allows the users to search for any item in the library. If the user finds that the required item is available in the library, he/she can checkout the item from the library. If the item is currently not available in the library, …show more content…
4.2 Scope This supplementary specification defines the non-functional requirements of the system such as reliability, performance, supportability, and security as well as functional requirements that are common across a number of use-cases. 4.3 Reference None 4.4 Common Functionalities • • Multiple users must be able to perform their work concurrently If the reserved item has been purchased or available, the borrower must be notified 4.5 Usability The desktop user interface shall be Widows NT or Windows 2000 compliant 4.6 Reliability The system shall be 24 hours a day, 7 days a week and not more than 10% down time 4.7 Performance • • The system shall support up to 2000 simultaneous users against the central database of any given data The system must be able to complete 80% of all transactions within 5 minutes 4 4.8 Supportability None 4.9 Security • • • The system must prevent borrowers from changing borrowers information, items information, titles information, and librarians information Only Librarian can modify borrowers information, items information, and titles information Only Master Librarian can modify librarians information 5 5. Use – Case Model 5.1 Actors Actor is something external to the system and interacts with the system. Actor may be a human being, device or some other software system. For Library system, actors might be; • • Librarian Borrower 5.2 Use – Case A use-case represents
5. The system must be able to compute the prices and find stores in less than ten seconds when the user presses
The system(s) are timely and extremely reliable, with no significant amount or frequency of system downtime and should enhance the flow of information to facilitate user and patient satisfaction.
Security shall be a high priority requirement. Since this system is intended for a wide range of users, it shall be user-friendly, requiring limited training and assistance.
Also if the system fails, all the information needs to be backed up and saved so it can be easily
The purpose of this section is to provide a description of the standards, practices, conventions, and
Centralized Data Management System and Database Server Hardware – This will be the central server in which data gathered by the tracking software will be uploaded to and downloaded from. All locations will have access to this hardware to share valuable customer information. This server will be used for customer data verification as well. It will also be the central sever in which data such as rewards program, points, purchases will be stored. The local database servers will have an Intel i5 processor, 8GB of RAM, and 2TB of storage to handle all the extra load and processing, while the central database server will have 4TB of storage.
Information Architect - Provides engineering, testing criteria, technical goals, works closely with Programmer, Technical Lead, and Network Admin.
Information will only have value if customers can access it at the right times. Availability can be affected by system errors, and malicious attacks as well as infrastructure problems. Availability is ensured by maintaining hardware as well as repairing hardware immediately when need arise. A correct functioning operating system should also be maintained in the environment free of software conflicts. Adequate communication bandwidth should also be addressed as well as preventing bottlenecks from occurrence.
Once an employee begins employment with a company he or she must first go through completion of the internship program. During the program the employee has a very important briefing that he or she completed on time, and then presented to the CEO of the company. The guidelines required to complete the briefing assignment consist of the explaining in detail the selection process, and how it was affected by the goals of the organization and stakeholders. The briefing will explain the process needed for selecting and acquiring an information system and how the goals of an organization can drive the selection of the system. The briefing will identify

The non-functional requirements are the attributes of the system; these include: reliability, performance, cost, system quality attributes, and the challenges encountered during installation.
By looking at the flow diagram above we can see that there are seven entities required in order to operate the database system accordingly to meet our specified criteria. The entities are as follows.
Describe the steps to be taken prior to inputting the data into the computerized system and how you would go about implementing the new system.
Requirement for interoperability, interfacing with systems operating environment (including; capability, temperature, humidity, radiation and robustness).
In India, some libraries and information centers made efforts to automate their library routines and services in the 1960’s. Nowadays most of the libraries have started or already have completed the process of computerization of their house keeping operations like, Acquisition, Cataloguing, Circulation, Serial Control, OPAC, etc. This article is a case study of the automation of library at DIHRM, New Delhi.
