# Design a database in UML without using ER diagram
|
||
|
|
The database can be designed using the Class diagram in UML, instead of the ER diagram.
|
||
|
|
## Approach
|
||
|
|
1. Identify the entities involved in the database.
|
||
|
|
2. Identify the attributes for every entity.
|
||
|
|
3. Identify the relationships between the entities.
|
||
|
|
4. For every entity develop a class diagram using UML.
|
||
|
|
5. The class name should be given as name of the entity identified in first step.
|
||
|
|
6. The attributes of each class should be taken as the attributes identified for the particular entity in second step.
|
||
|
|
7. The operations can be left empty for every class, as the entities will not be having any operations in database.
|
||
|
|
8. These classes can be joined using the association relationship in UML, as per the relationships identified in third step.
