Chapter 4 Defining the Accesses to Adabas : Task F: Map Adabas External Data to TIBCO Object Service Broker Types

Task F: Map Adabas External Data to TIBCO Object Service Broker Types
This section describes how to map Adabas external data to TIBCO Object Service Broker types.
Understanding the Default Mapping of Adabas External Data Types
The following table shows the default mapping of Adabas external data types to TIBCO Object Service Broker semantic data types, syntax, and lengths. Changing the Defaults describes the Adabas data types that can be converted to TIBCO Object Service Broker syntax. The supported TIBCO Object Service Broker semantic data types, syntax, and lengths are described in TIBCO Object Service Broker Programming in Rules.

Changing the Defaults
You can modify attributes in the TIBCO Object Service Broker field definition area using the values described in Fields in the Metadata Definition Area. The following options are available:
Change the entry in the Name field to a new name to uniquely identify the field within the ADA table. You can name a field the same as a field in another table; if you are moving data between tables, giving the fields the same name simplifies the process.
Change the TIBCO Object Service Broker semantic data type (Typ field) and syntax (Syn field) of the field. You can use any valid TIBCO Object Service Broker semantic data type (except date) and syntax (except floating point), provided the combination is valid. TIBCO Object Service Broker Programming in Rules lists valid combinations.
Changing the TIBCO Object Service Broker field syntax can cause a conversion error, since each affected field of each row to the new syntax as defined in the ADA table definition must be converted.
 
Requesting Adabas Data Conversion
TIBCO Object Service Broker can request Adabas data in a different format than the one in which the data is stored. Do the following:
1.
2.
Having TIBCO Object Service Broker request the data from Adabas forces Adabas to perform the conversion, which is more efficient.
TIBCO Object Service Broker can potentially convert this data again to the format described by the Metadata half of the field definition. To avoid the overhead of performing two data conversions, make these two formats the same.
The required syntax is specified as an TIBCO Object Service Broker external syntax not an Adabas syntax. It is then converted to an Adabas syntax.
