An introduction to the use of relational (SQL) databases, with a brief overview of database structure then covering SQL queries, some information on best practices, and development tools. We will mostly deal with ANSI SQL which will run on most Relational Database Management Systems (RDBMs), noting some important inter-RDBMS differences. Covered will be SQL queries for data retrieval, insertion and deletion, correlated subqueries and how to construct a complicated query. We will also discuss the interface between the database and the code, including the use of Object-Relational Model tools and stored procedures.
