Library Information System Design: Using Unified Modeling Language (UML) Architecture

"Knowledge is power", and the power house of knowledge is the library. Technology has pervaded all spheres of human activities, including library services. An organised library is a must in institutions of learning at all levels. Thus, in this age of technology, automating library services becomes the way to go. So, using Office Technology and Management Department as case study, this work developed a computer-based one-stop-shop, library information system that is user-friendly for proper inventory of library resources. Following observations, interviews and review of existing documentation, the Structured System Analysis Design (SSADM) and Knowledge Engineering Methodologies were used for problem analysis and design. Unified Modeling Language was used for the design, with underlying database interface using CSS and HTML and a back-end PHP framework. This system would ensure improved services for libraries due to better storage and retrieval. This work should especially pique the interest of institutions of learning, software programmers, library managers, information technologists and indeed all individual book lovers who own or intend to own private libraries.
