Hi everyone,
I need to store control and spec limit data for iSPCChart applets. I've read the documentation for the iSPCChart and the relevant bit seems to be this:
The data must be returned in dataset format with the columns in the following order: effectivity date (datetime datatype), LCL (number datatype), target (number datatype), UCL (number datatype). The resulting set can have multiple rows. You can use the effectivity date and the datetime value of the returned data to determine which set of limits to use.
Our current MII 11.5 implementation stores this data in a SQL DB called QualityPortal that also stores point supression and comments. I don't know the complete history of this implementation but it looks to me that the comment and point supression tables were created by a script that came with MII. I'm not sure about the origin of the "ControlLimitDetails" and "SpecificationLimitDetails" tables. MII 11.5 successfully reads and writes comments and suppressed points from this DB when using the applets.
I had a look at the DB schems of MII 14 and found tables XMII_QPCOMMENTS, XMII_QPSUPPDPOINTS, and XMII_QPSUPRSDPOINT, which work for comments and point supression but there don't seem to be any tables for storing limit info.
My question is what is the best practice for storing the limit data? Should we create a new SQL database just for this? Should we add tables to the XMII DB? Is there a script that will create the necessary schema? Should we just keep our existing DB even though comments and suppressed points won't be there anymore?
Thanks,
Allan
