VSAM-SQL Bridge
is an important capability allowing existing batch COBOL business
applications to connect to RDBMS-housed data extracted from legacy
VSAM data sets.
|
No Code Changes
VSAM-SQL Bridge provides the capability
to maintain existing COBOL application VSAM I/O data definitions;
while at execution time continue to access VSAM data that has been
migrated into RDBMS tables.
VSAM-SQL bridge works in combination with
LegacyJ PERCobol Transaction to provide an easy migration path to open
platforms for batch COBOL. The VSAM-SQL bridge has no dependences on
LegacyJ Transaction Platform, and provides an easy migration path for
batch COBOL applications.
Function
VSAM-SQL permits applications
that are heavily dependent on VSAM I/O to migrate to OPEN systems
without syntax changes. Functions available are:
-
Access KSDS VSAM Datasets
-
Support for all VSAM Input/Output Statements (OPEN, WRITE,
START, READ, READ NEXT, REWRITE, DELETE, CLOSE)
-
XML File Descriptors to define datasets used in a
non-transaction environment.
