The Table Analyzer Wizard can help you create a relational database from a set of data. When you use the Table Analyzer Wizard, you do not have to know relational database design principles. This article explains how the Table Analyzer Wizard deciphers a single-table database and proposes a way of splitting the original table into a set of related tables.
The Table Analyzer Wizard can automatically analyze a nonrelational database and "normalize" it for you. Normalization is the process of taking a single-table database and breaking it into a set of smaller, related tables, with each table focused on a single topic or grouping of information.
A normalized relational database has a number of advantages over a nonrelational one. First, updating information is faster and easier because fewer data changes are required. Second, only the minimum information is stored; therefore, the database is smaller. Finally, a relational database keeps data consistent automatically because data is stored once.
Although the Table Analyzer Wizard can help you create a relational database, if you have database experience, the Table Analyzer Wizard enables you to modify any suggestions it makes. You can split up tables, rearrange fields in tables, and create relationships between tables. You can modify Table Analyzer Wizard decisions during every step of the database-creation process.
