DBLC ( DataBase Life Cycle): DBLC is a sequential process which is used to trace the history of the application that is present within the information system . The history of the application can be traced from the beginning till its last even though being outdated. DBLC is concurrent to Software Development Life Cycle (SDLC) because the database represents the core of the information system. It is composed of six phases: Initial study: Examining the operations of the current system. Design: It focuses on designing the database model which satisfies both operation and objectives of the company. Implementation and loading: It is a process of designing the specifications. Testing and evaluation: Ensure the database performance. Operation: The process that is designed to make it operational. Maintenance and evolution: Performs routine maintenance activity within the database.

Question

An educational institution wishes to maintain a database of its employees. The database is divided into a number of classes whose hierarchical relationships are shown in Figure . The figure also shows the minimum information required for each class. Specify all the classes and define functions to create the database and retrieve individual information as and when required.

Specification Suppose you are asked to design a club database system based on the _following information. Each student has a unique student id, a name, and an email; each club has a unique club id, a name, a contact telephone number, and has exactly one student as its president. Each student can serve as a president in at most one of the clubs, although he/she can be the members several clubs. Clubs organize activities and students can participate in any of them. Each activity is described by a unique activity id, a place, a date, a time and those clubs that organize it. If an activity is organized by more than one club, different clubs might contribute different activity fees. Question Draw an E-R diagram for the system according to the above description.
