data type
The structure of a value that constrains its characteristics, such as the information the values can hold and permitted operations. In report development, three processes use data types: accessing data, internal processing of data, and formatting output as a report.
Data types in Actuate SQL include Decimal, Double, Integer, Timestamp, and Varchar. In the IO Design perspective, Actuate SQL data types map to data types in supported databases.
Internal data types used by BIRT technology include Date, Double, Integer, Varchar, Time, and Timestamp. These data types map to the Java constants declared in Java.sql.Types, such as DATE, DOUBLE, INT, and STRING. BIRT maps the data types from supported data sources to these internal data types. To format values in a report, BIRT provides date-and-time, number, and string data types.
