What is a database? Why database? Data independence. Relational systems and others. 2. Database System Architecture. The three levels of the architecture. The external level. The conceptual level. The internal level. Mappings. The database administrator. The database management system. Data communications. Client/server architecture. Utilities. Distributed processing. 3. An Introduction to Relational Databases. An informal look at the relational model. Relations and relvars. What relations mean. Optimization. The catalog. Base relvars and views. Transactions. The suppliers-and-parts database. 4. An Introduction to SQL. Overview. The catalog. Views. Transactions. Embedded SQL. Dynamic SQL and SQL/CLI. SQL is not perfect. II. THE RELATIONAL MODEL. 5. Types. Values v Variables. Types v Representations. Type Definition. Operators. Type generators. SQL facilities. 6. Relations. Tuples. Relation types. Relation values. Relation variables. SQL facilities. 7.

A closer look. Predicates and propositions. Relvar predicates and database predicates. Checking the constraints. Internal v external constraints. Correctness v consistency. Integrity and views. A constraint classification scheme. Keys. Triggers (a digression). SQL facilities. 10. Views. What are views for? View retrievals. View updates. Snapshots (a digression). SQL facilities. III. DATABASE DESIGN. 11. Functional Dependencies. Basic definitions. Trivial and nontrivial dependencies. Closure of a set of dependencies. Closure of a set of attributes.
