A database model is a type of data model that determines the logical structure of a database and fundamentally determines in which manner data can be stored, organized and manipulated. The most popular example of a database model is the relational model, which uses a table-based format.
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
I've been building up a REST services API, consisting of a dozen or so classes referenced from a Dispatch class, which has route mappings for the first piece of the URI. I'd like to have the Dispatch class be able to output all of the available Services, with some documentation. Is there something like a %Library resource that I could use to pull this information from each of the classes?

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.
We have a case where a vendor can send us more information in the DICOM message rather than in the HL7 result message. In theory it should be possible to take a DICOM and convert it to HL7, stupid question is has anyone done it before? Does anyone have any good examples of a DTL they did to show me how to setup the message structures and translation?
Is there a way to read JSON and transform it (in DTL) by using a VDOC of this JSON (without transform it to internal message) like I can do with HL7 or XML?
If it possible, I guess that I should have a schema of the JSON so the second question is how to build a schema for JSON and load it to the IRIS?
I would like to know if anyone has had some experience in building systems for multiple end-users.
To keep things simple, in a hypothetical example, say an Event Booking System, where a Venue could sign up to use such a system and define it's Venue, costs, calendars, etc.. and then invite their customers to book the Venue on different days/times.
If I wish to offer such a system to many Venues, there are a number of options available.
In the first one, I have defined a class which Extends (%Persistent, Ens.Util.MessageBodyMethods), we'll call it NSOne.Msg.Req
In the second namespace NSTwo, I want to use the previous class with something like SET pInput = ##class(NSOne.Msg.Req).%New()
I mapped the NSOne.Msg.Req package in namespace NSOne. In Atelier, I can see NSOne.Msg.Req in my NSOne. But, when I try to execute line 2 above, it tells me :
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?
I have been following the online Zen Quickstart Tutorial using the lastest release documentation. In addition to playing around with the styling and making a few minor functionality tweaks, I wanted to add an additional column that shows a count of the number of phone numbers for that Contact (as shown in the image below).
Just curious to know about the pros and cons of Parent/Child Vs One/Many.
We do use a bit of both. One big reason we use Parent child is we feel if we delete one global, it gets rid of all child data too and all parent child data is stored in one global. Much easier to manage.
1. The %ObjectSelectMode is working perfectly in the DynamicSQL for the object property in direct query. However this is not supported for class query. Is there any way to resolve this / Get the object value for class query result.
First time post, also a new Cache developer, hence the <Beginner> tag.
If our data has Predefined terms in a dictionary, and a user can add terms on their own, can the terms exist in different tables?
Lets call the tables "Terms" and the user data in "UserTerms".
If a third class definition has a property of "Term" can it not be either Terms or UserTerms?
I'm leaning towards using a Subclass strategy where the pseudo "Parent" (forgive me) is Dictionary.Term and the child is along the lines of Dictionary.Term.User
We find ourselves at a crossroads in our development journey, and we're reaching out to the community for insights and guidance regarding a critical aspect of our data management strategy.
