tcACCESS – Features

Data Mapping and Intelligent Import Functions for any file structures

To avoid the manual definition of Mainframe file structures, tcACCESS can automatically import data structures defined in source programs or in copybooks. All relevant data formats are automatically recognized (packed, zoned, hexadecimal, alphanumeric, binary etc.). Redefined data structures are also supported.

 

Data Mapping and Intelligent Import Functions for databases

Segment data structures for DL/I and IMS/DB are automatically imported like any other file formats. Specific information for accessing the database (SSA information) is automatically retrieved from DBD and PSB modules. This information is important, because tcACCESS bases the access strategies on this information. Especially for decisions to perform a keyed or a sequential access.

For ADABAS and CA-Datacom/DB, the corresponding data dictionary system will be used (i.e. PREDICT). Database specific information is automatically recognized (Index information, Descriptor and Super Descriptor Information, Periodic Group Fields, Multiple Fields etc.). The resulting tcACCESS field definitions are presented to the administrator and changes may be applied if needed.

SCHEMA data will be evaluated for CA-IDMS. All information necessary to establish the proper relationships are automatically extracted.
