Library Information System Data flow diagram is often used as a preliminary step to create an overview of the Library without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Library process. It contains all of the userflow and their entities such all the flow of Student, Planning the Acquisition of Materials, Book Maintenance, Fees Collection, Membership Management, Facility, Login. All of the below diagrams has been used for the visualization of data processing and structured design of the Library process and working flow.
Zero Level Data flow Diagram(0 Level DFD) of Library Information System :
This is the Zero Level DFD of Library Information System, where we have eloborated the high level process of Library. It’s a basic overview of the whole Library Information System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Membership Management,Facility and Login showing the system as a single high-level process, with its relationship to external entities of Student,Planning the Acquisition of Materials and Book Maintenance. It should be easily understood by a wide audience, including Student,Book Maintenance and Membership Management In zero leve DFD of Library Information System, we have described the high level flow of the Library system.High Level Entities and proccess flow of Library Information System:
- Managing all the Student
- Managing all the Planning the Acquisition of Materials
- Managing all the Book Maintenance
- Managing all the Fees Collection
- Managing all the Membership Management
- Managing all the Facility
- Managing all the Login
First Level Data flow Diagram(1st Level DFD) of Library Information System :
First Level DFD (1st Level) of Library Information System shows how the system is divided into sub-systems (processes), each of which deals with one or more of the data flows to or from an external agent, and which together provide all of the functionality of the Library Information System system as a whole. It also identifies internal data stores of Login, Facility, Membership Management, Fees Collection, Book Maintenance that must be present in order for the Library system to do its job, and shows the flow of data between the various parts of Student, Book Maintenance, Facility, Login, Membership Management of the system. DFD Level 1 provides a more detailed breakout of pieces of the 1st level DFD. You will highlight the main functionalities of Library.Main entities and output of First Level DFD (1st Level DFD):
- Processing Student records and generate report of all Student

- Processing Fees Collection records and generate report of all Fees Collection
- Processing Membership Management records and generate report of all Membership Management
- Processing Facility records and generate report of all Facility
- Processing Login records and generate report of all Login
Second Level Data flow Diagram(2nd Level DFD) of Library Information System :
DFD Level 2 then goes one step deeper into parts of Level 1 of Library. It may require more functionalities of Library to reach the necessary level of detail about the Library functioning. First Level DFD (1st Level) of Library Information System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Login, Facility, Membership Management, Fees Collection, Book Maintenance, Planning the Acquisition of Materials, Student.Low level functionalities of Library Information System
