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.
Is there a data model for the Ensemble EnsLib_HL7 tables in the database? A client wants to run some SQL and would like some documentation about table relationships.
As you know there are two (at least) ways to get the stored value of the property of InterSystems IRIS class if you know the ID of an instance (or a record).
1. Get it by as a property of an instance with "Object access":
ClassMethod GetPropertyForID(stId As %Integer) As %String
{
set obj=..%OpenId(stId)
return obj.StringData
}
2. Get it as a value of a column of the record with "SQL access":
is there any indication that the .NET object representation of Cache objects (i.e. InterSystems.Data.CacheClient.dll) complies with .NET Standard? I'm planning to extend our existing .NET client/server solution with a mobile option by Xamarin Forms and can't find any significant hints in the internet.
I'm just fooling around a bit and made some expreiments with a REST API and a generic object-to-JSON tier:
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
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.
