Second Level Data flow Diagram(2nd Level DFD) of E-Library Management System :
DFD Level 2 then goes one step deeper into parts of Level 1 of E-Library. It may require more functionalities of E-Library to reach the necessary level of detail about the E-Library functioning. First Level DFD (1st Level) of E-Library Management System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Author, Books, Durations, Fees, Schedules, Students, Course.Low level functionalities of E-Library Management System
