Student Information

Book Information

Borrowing and returning Process


The purpose of the Library Management System is to manage Borrowing and receiving books from the student and updating book information for every transaction ( both Borrowing & receiving) . Functionality of System: 2. Student Information:

It includes the student information for Borrowing and returning the books with the updated books information.

21

3. Book Information:

It includes Book Information such as Author name ,Code, account number , Publisher name,Date of Issue and Date of returning ..

4. Borrowing and ending Process

It displays the information about the books issued ,burrower,returning date ,duration to have the books.

SOFTWARE TESTING

The main objectives of testing to maximize the test case , minimize the number of errors,

focus on correctness and efficiency of program.It helps to find out details of the student

who have borrowed the particular books.Both the Book information ,student information

can be obtained.

EX: NO: STUDY EXPRIMENT TO DESIGN E-R MODEL

AIM

To design an Entity-relationship model.

PROCEDURE

STEP 1: Start

STEP 2: Specify attributes and identify the primary key for Entity.

STEP 3: Formulate the relation between entities.

STEP 4: Ensure that all the entities have been modeled.

STEP 5: Normalize the entire model.

STEP 6: Stop

DESCRIPTION OF ENTITY-RELATIONSHIP SYMBOLS

1. Rectangle It represents Entity Sets

2. Ellipse It represents Attributes

3. Diamond It represents Relation Set

4. Lines It represents Link between attributes to entity set and entity set to relationship set.

5. Doubled Ellipse It represents derived attributes.

6. Dashed Ellipse It represents primary key

7. Double Lines It represents participation of an entity in a relationship set.

8. Weak Entity Set An entity which does not pass any attribute for primary key

9. Strong Entity Set An entity which passes a dominant parametric feature for unique identification.

43

E-R MODEL FOR BANKING ENTERPRISE

Result: Thus the E-R Model has been studied and acquired the knowledge.
