After reading the pdf:
- – To understand and analyze the different issues involved in the design and implementation of a database system & design EER
- – To understand and use queries using relational algebra and SQL DDL and DML commands to manage the database. Design Normalized tables.
- – To understand the file storage , indexing structures and query optimizations algorithms
- – To develop an understanding of essential DBMS concepts such as: database security, transaction processing and recovery.
Topics Covered are:
Database system architecture: Data Abstraction, Data Independence, Data Definition, Language (DDL), Data Manipulation Language (DML). Data models: Entity-relationship model, network model, relational and object oriented data models, integrity constraints, data manipulation operations.
