Business Intelligence Relational Database Systems TrainingA relational database is a database that has a collection of tables of data items, all of which is formally described and organized according to the relational model. In the relational model of a database, all data is represented in terms of tuples, grouped into relations. Most relational databases use the SQL data definition and query language; these systems implement what can be regarded as an engineering approximation to the relational model. A table in an SQL database schema corresponds to a predicate variable; the contents of a table to a relation; key constraints, other constraints, and SQL queries correspond to predicates. This trainings provides you with an overview of the key concepts of the relational model and relational databases. After completing this course, you will be able to design entities and their relationships in a conceptual model and then create a relational table structure based on this first model.
