#Data Model

Hey Community,
I have an scenario, please advise or suggest possible ways to solve it.
So i have a persistent class to test results of a diagnostic laboratory. The properties are 

• Patient name
• Type of Test
• Order ID

Hello all; I am using a one-to-many relationship.  I have a Claim (one), in a relationship with Lines (many), but the Claim is storing a list of Lines IDs, rather than the Lines storing the Claim Id.  This seems upside down, and not what I expected.

Class Claim

{
    Relationship ClaimLineRel as ClaimLine [Cardinality = many, Inverse = Claim];
}

Class ClaimLine
{
    Relationship Claim as Claim [ Cardinality = one, Inverse = ClaimLineRel, OnDelete = cascade];
    Index ClaimIndex on Claim;
}

But the storage globals for Claim show data in the ClaimLine spot:

^ClaimD(1)=$lb("",$lb(2,3).

Hello community,

is there anything special to consider when running a foundation production regarding purge jobs (Ens.Util.Tasks.Purge)? I am thinking specifically of the QuickStreams, which according to my information are stored in a temporary database until the system is restarted. Since a system reboot is much less frequent then the purges, I wonder what happens to the QuickStreams whose messages and headers have already been purged. Is there a way to view Quickstreams (not content, but rather metadata) e.g. via the Management Portal?

Thanks for your comments and hints,

best regards, Martin

Hello! 
So my question is quite simple, Do the different data models of Intersystems all support the ACID properties?
I assume that for the SQL data model implementation it does, But does it also work for global (i.e the hierarchical  data model)?
I searched the docs and the different articles, It seems for example that here its implied that the different data models of Intersystems  DO indeed support the ACID properties and allow for safe insertion, deletion etc... in concurrent operations to the server that is.

Would love to get a clarification, Thx!

Hello,

Our software commonly returns a full result set to the client and we use the DataTables plugin to display table data.  This has worked well, but at datasets grow larger, we are trying to move some of these requests server-side so the server handles the bulk of the work rather than the client.  This has had me scratching my head in so many ways.  

I'm hoping I can get a mix of general best practice advice but also maybe some IRIS specific ideas.
