Our esteemed colleague and moderator Chuck Barouch has/had a product called Zeus which does/did transfers like this. If he can avoid self-censorship for a moment I would invite him to respond to this inquiry with his own experience in this area. As time permits I have been writing demos to show an MV DBMS populating SQL Server. As I said in another post today, the communications pipe is unimportant as is the DBMS. The same demo can be used for any MV DBMS and for any RDBMS, all someone needs to do is change the SQL query or stored procedure, and match the RDBMS fields to fields retrieved from the MV side. It comes down to a simple bit of X-to-Y mapping of fields and ensuring data types are properly managed. I'm sorry that I do not yet have a video of this on our website but I did show this demo and others along with code in my recent presentation to SAPUG. Maybe I can kick off a discussion of numbers: Without any optimization and on an over-burdened 2GHz laptop I'm getting about 200 records per second extracted from MV and Inserted into SQL Server. SQL Updates on the same data is roughly about 1/2 that. Amongst other business responsibilities I'm trying to find time to optimize the queries on both sides and run on a system which is more likely to generate production-quality numbers. I have a 3GHz dual core Athlon that should yield some good numbers soon. I'd appreciate it if someone else can provide some other realistic numbers so that I have a goal for acceptability. As a low-priority development project, and driven by common requests we find here, we have a package which moves data from any MV environment to any RDBMS. It allows for construction of a query string for about 15 different relational sources and that X/Y mapping of fields and data types. I wish this were further along so that I could provide some numbers about transfers from U2 to Excel, QM to Oracle, D3 to DB2, Reality to Interbase, etc. I would welcome discussion with someone who can help to drive this development. <minor_rant> If that's too subtle, and at the risk of soliciting, we can't proactively develop tools like this unless we get financing, and you only get people to fund projects if you ask. That's not an ad, it's a fact of business. More solutions would be available for common problems if this community were more willing to match supply/talent with the demand of ongoing business needs. As it is, for years we continue to see the same data transfer problems presented every week as though it's the first time someone is asking the question. </> Tony Gravagno Nebula Research and Development TG@ removethisNebula-RnD.com Active updates of local fires in southern California, with map: removeNebula-RnD.com/blog/cosmos/earth/2007/10/local-fires1.html ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
