Library System Documentation
System Description and Definition
An Online Library Management System refers to a computerized information system
which enables library users to electronically access and manage library services and resources in
an easy way that reduces manual and paper work. With the system, a lot of time that would be
wasted in searching for library resources manually is saved while cases such of files being lost or
misplaced are eliminated. (Prabhakar, Rahul, Rajat, & Vikram, 2014).
Gantt chart
This a popularly accepted tool and technique that is used to during project planning and
scheduling to represent all activities, and processes involved or to be undertaken during software
development. The activities are represented such that each is matched against assigned team that
are to do tasks involved plus the expected timelines. Breaking down the processes into charts and
bar graphs gives a better understanding of the software, not only to the developers but to the
clients and system users as well. Chart bars are at times used to show percentages of activities
that are complete and ongoing. Gantt charts presents to developers a very useful tool for project
managers to plan and schedule all projects activities, and trace them accordingly (Pankaja,
2005).
Below is a Gantt chart for the library management system.
