635.0. "Revere VIDA product?" by VFOVAX::TYSON (Sandy Tyson @vfo) Tue May 01 1990 22:27

    Does anyone know of a "reverse-VIDA" product.  By this, I mean a
    product to reside on an IBM 3090 which will allow read access to 
    an Rdb data base.  (I'm not looking for a VT terminal emulator to 
    access a VAX, but a VIDA-like product).
    
    Thanks in advance,
    Sandy Tyson

    IBM announced a future product called "DXT" or "DPXT" last fall. It was
    supposed to do batch extracts from many different database selections
    on the VAX and bring the data over tpo the ibm. I do not know if it is
    shipping, just that it was announced.
    
    Similar to VAXlink, not VIDA for DB2

635.2DXT/D1 -- it's not VIDASQLRUS::THOMASTue May 08 1990 01:1729
    IBM has an extraction tool called DXT (Data Extraction Tool).  DXT can 
    be used to extract data from IMS, DB2, SQL/DS, and VSAM, and load the
    data into DB2 or SQL/DS.  (Perhaps we should devise such a product to 
    work with Rdb, RMS, DBMS, etc.)  
    
    They recently released an extension to this product, called DXT/D1.
    DXT/D1 extracts data from the VAX environment, transfers it across a
    DECnet/SNA gateway or VMS/SNA, and loads it into DB2 or SQL/DS.  DXT/D1
    runs on VMS and can access Rdb, RMS, and ORACLE.  It has a programmable
    interface, so you could program it to speak to other VMS-based database
    systems.  As Barry said, it is much more like VAXlink than like VIDA.
    
    IBM has no plans in place (that I'm aware of) to implement a VIDA-type
    product -- ie, a transparent direct heterogeneous access tool.  DEC
    could build a direct heterogeneous access tool, but we would not be
    able to provide transparent access without modifying DB2.  We have
    no plans to modify DB2.  
    
    We do plan to support SQL Access -- a direct heterogeneous access
    standard currently being developed by a consortium of database
    companies.  We are actively involved in the SQL Access consortium.
    IBM is not a member of the consortium.  They have not commented on
    their plans to support SQL Access.  
    
    We do not plan to produce a "reverse VIDA" product specifically for
    DB2.  We plan to support SQL Access queries to other databases that
    support SQL Access, and to support SQL Access queries from other 
    databases that support SQL Access.  I suspect that IBM customers will
    encourage IBM to support this new emerging standard.
