Designing databases
The first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.

The Informix® Database Design and Implementation Guide provides information to help you design, implement, and manage your Informix databases. It includes data models that illustrate different approaches to database design and shows you how to use structured query language (SQL) to implement and manage your databases.

Synonym behavior

Synonyms are always private in an ANSI-compliant database. If you attempt to create a public synonym or use the PRIVATE keyword to designate a private synonym in an ANSI-compliant database, you receive an error.

For more information, see the description of the CREATE SYNONYM statement in the Informix® Guide to SQL: Syntax.
