Chrysalis allows organisations to maintain their investment in robust and proven applications while opening them up to contemporary databases and lower cost environments.
Open your legacy applications to:
|
• |
leading edge development and reporting tools |
| • | WEB channels. |
Lower the cost of ongoing development:
|
• | through the use of modern software tools. |
Allow legacy COBOL applications to access powerful relational database IO operations:
|
• | easily embed recordset functionality into legacy COBOL applications using native I/O methodologies
|
| • | use triggers to create virtual files
containing only active records for improved performance |
|
|
• |
use triggers for comprehensive auditing independently from application code | | • | use
differential backups or database replication for recovery & load sharing. |
Chrysalis is a unique set of tools that facilitates
the migration of data from COBOL’s native file structures to a relational
database.
Chrysalis does not impact business logic within the application:
|
• |
There is no change to the underlying source code thereby decreasing risk and extending the life of applications |
| • |
No need to retrain users as the application look & feel remains the same |
| • |
Chrysalis caters for COBOL record locking, multiple record formats, occurs clauses and redefines clauses |
| • | The benefits of an RDBMS can be realized quickly with low risk and minimal disruption to business operations. |
|
Chrysalis replicates the behaviour of COBOL’s File Handler, inlcuding record locking & error handling, thereby isolating the legacy application from the data structure required for its data to reside on SQL Database. Legacy application is unaware its data resides on SQL Database.
