Data on the go for businesses on the move



WHAT IS IBM DATAPROPAGATOR NONRELATIONAL?

     IBM* DataPropagator* NonRelational maximizes the value of your IMS*
     assets by enabling you to replicate IMS data across the DB2* family
     of databases.  DataPropagator NonRelational captures changes that
     have taken place in the IMS database and applies them to copies in
     DB2 for MVS.  A companion product, DataPropagator Relational, can
     further distribute this data to client/server systems across the
     enterprise.  So you can periodically synchronize target DB2
     databases with the point-in-time state of a source IMS database.



WHAT YOU CAN DO WITH IBM DATAPROPAGATOR NONRELATIONAL

     DataPropagator NonRelational can help speed the implementation of
     new business solutions by allowing businesses whose core
     operational systems are on IMS to develop complementary
     applications on the database of their choice.  Businesses with
     IMS-based systems have a significant investment in their
     operational applications, which are the backbone of their
     enterprises.  DataPropagator NonRelational and IBM's Data
     Replication solution enable such businesses to extend their IMS
     applications with new components based on relational technology.



LEVERAGE IMS DATA FOR DECISION MAKING

     By propagating changes from IMS databases to copies of those
     databases in DB2, you can implement decision support applications
     that use relational technology without affecting any existing IMS
     applications.  By some estimates, about half the total application
     backlog can today be satisfied via end-user tools, and most
     end-user decision support tools rely on underlying relational
     technology.

     By enabling non-DP oriented users to participate in creating
     solutions to their own backlog of applications, you can enhance the
     overall competitiveness of your enterprise.



IMPLEMENT EFFICIENT REPLICATION ENVIRONMENTS

     DataPropagator NonRelational performs asynchronous change
     propagation -- that is, the change is applied independently of the
     updating application.  This means you can apply changes at
     predetermined intervals, managing replication according to your
     business needs.  Changes are captured from the IMS archive logs
     (SLDSs) to minimize any impact to transaction response time.  The
     interval between updates may be as small as the log archive
     interval, or as great as the business requires.  The IMS and DB2
     systems may reside on the same or different MVS systems and run
     under either IMS Transaction Manager or CICS*/DBCTL.



ENABLE IMS AND DB2 APPLICATION COEXISTENCE AND MIGRATION

     DataPropagator NonRelational also supports synchronous replication
     from IMS to DB2, from DB2 to IMS, or in both directions
     simultaneously.  Changes are applied immediately, in the same
     unit-of-work as the updating application, providing fully
     synchronized copies between IMS and DB2.  Using DataPropagator
     NonRelational's synchronous two-way propagation capabilities, you
     can support two master copies of the same data, one in IMS and one
     in DB2.  Full synchronization allows for co-existence of IMS and
     DB2 applications or for incremental, controlled migration from IMS
     to DB2.  Data shared across IMS and DB2 is synchronized without
     requiring changes to the application using the data.  Synchronous
     replication requires that both the IMS and DB2 systems reside on
     the same MVS image and run under IMS Transaction Manager.



DATAPROPAGATOR NONRELATIONAL AND IBM'S DATA REPLICATION SOLUTION

     DataPropagator NonRelational extends IBM's Data Replication
     solution to the IMS environment.  It allows you to maintain your
     investment in your IMS operational data stores while leveraging the
     data for new client/server applications.

     DataPropagator NonRelational supports the direct application of IMS
     changes into IBM's data staging area on DB2 for MVS.  From there,
     DataPropagator Relational can enhance, distribute, and apply those
     changes to relational databases across the enterprise.  So you can
     customize IMS data to meet your application requirements, including
     re-formatting, summarizing, translating, joining, or deriving data.
     And DataPropagator Relational will selectively distribute and apply
     data to target databases at intervals you specify.

     While an ISPF administration interface is provided, DataPropagator
     NonRelational can also exploit the source-to-target mappings
     defined with IBM DataRefresher's graphical user interface (GUI).
     When used together, DataPropagator NonRelational and DataRefresher
     give you coordinated refresh and update processing of data from IMS
     databases to DB2 databases.



NEW FEATURES IN DATAPROPAGATOR NONRELATIONAL VERSION 2

     DataPropagator NonRelational Version 2 provides the following key
     enhancements over Version 1:

     * New support for asynchronous propagation from IMS to DB2
     * Interoperability with the IBM DataPropagator Relational data
       staging area and IBM's Data Replication solution
