This course provides you with an introduction to database architecture and relational databases. The introduction covers the basic concepts of database design and management, focusing on the steps that a database designer should follow when creating a database for use with an application, addressing the basic tasks encountered by a database administrator, and identifying and discussing some of the aspects of ongoing database management.

In Week One, you are introduced to a variety of different database architecture types, from data that is stored in flat files and XML, to legacy database architecture such as network and hierarchical structures.
