You should now have successfully designed and deployed a framework to use MDS effectively.
How it works...
The package deployment process is a pre-defined process within MDS that follows the steps
to create a package of a model from the source system (file based), and deploy it to a defined
MDS environment. The Model deployment wizard can be used to create a new model or
update an existing model. When creating a deployment package, we can decide whether or
not to include data. If data is included, then we must select a version of data that will compile
the data by using the MDS staging process.
It is essential to know about the model view presentation that represents various components
for each model object, such as:
F Model: Highest level of data abstraction layer, which contains multiple entities and
other related objects
F Entities: These are objects in the MDS model and a container of members, which are
defined by various attributes
