Using Data Modeling Tools to Create Access Databases

Data modeling tools are available from several publishers for designing and then automatically creating the structure of client/server relational databases, such as SQL Server, ORACLE, and SQLBase. Data modeling tools that run under Windows let you use graphic techniques, such as E-R diagrams, to design the structure of the tables and establish relationships between the tables. Database CASE tools save much time and prevent many errors when you implement a large and complex relational database.

Note

Data modeling tools often are called Computer-Aided Software Engineering (CASE) tools. CASE tools designed for enterprise-wide software design usually include data modeling as one of their features. Today's high-end CASE tools, some of which carry license fees of $100,000 or more, offer many additional capabilities. This book positions data modeling tools as a subset of CASE tools.
