many ways to evaluate even this simple query‚ each of which is superior in certain situations‚ and the DBMS must consider these alternatives and choose the one with the least estimated cost. Queries that consist of several operations have many more evaluation options‚ and finding a good plan represents a significant challenge. A more detailed view of the query optimization and execution layer in the DBMS architecture presented in Section 1.8 is shown in Figure 13.1. Queries are parsed and then presented

E-R Diagram Introduction:- In 1976 ‚Chen developed the Entity-Relationship Diagrams ‚a high-level data model that is useful in developing a conceptual design for database . An ER diagram is a diagram containing entities or “items”‚ relationships among them‚ and attributes of the entities . The E-R model is one of the best known tools for logical database design. Within the database community‚ it is considered a natural and easy-to-understand way of conceptualizing the structure of database.
