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.
Designing and Implementing a Database
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.

Select a currency format

To customize this currency format, select your locale appropriately or set the DBMONEY environment variable. For more information, see the Informix® Guide to SQL: Reference.

Global Language Support (GLS)

Each nation has its own way to display money values. When the Informix® database server displays a MONEY value, it refers to a currency format that the user specifies. The default locale specifies a U.S. English currency format of the following form: $7,822.45

For non-English-language locales, you can use the MONETARY category of the locale file to change the current format. For more information about how to use locales, see the Informix® GLS User's Guide.
