In this session I presented how Common Data Service will be the future of Phone, Website • Data constructs • Support for modeling relationships, . wire to the Common Data System endpoints • Advantage of API is a higher. How to model data with the Kinvey Data Store. To effectively model your data in Kinvey it's useful to understand the difference between normalized data and. Common Party type's include individuals and organisations. A Party may have one or more relationships with the Enterprise and with other (involved/related) Parties. Rob Ferguson: A collection of data models that provide solutions to common problems in database Flowable's REST API - Part 1.
The Common Data Model
You should ask yourself questions like: Does my app collect large amounts of data from various sensors? Does my app have social features linking users together? Does my app need to have a really complex series of drill-down views?
Does my app have different users trying to update groups of items at the same time?Relationships - Beginning Core Data - kinenbicounter.info
Does my app read data more fetch from the server or write data more save to the server? These questions should drive the models that you use for your data.
Thinking about how your users interact with data makes it really easy to choose an optimal way to organize your data. As you work more on your application the answers to these questions may change.
Embedding The Kinvey data store allows you to store very complex data as values. This is modeled by an awards array, each element containing an object that lists the event and the awards received at that event. References The other basic way to model relationships with your data in Kinvey is called references and uses the unique id field required by all entities that are saved to the appdata service.
Understanding the Common Data Model
Classes Have the following characteristics or rules: A Class is a construct used to group related attributes. Classes are the representation of a resource instance type for example, an OperatingSystem as a type of resource instance.
As the basic structure of the model, classes contain attributes, implement interfaces, and can optionally be involved in relationships. Classes are hierarchical and inherit the properties of parent classes.
Classes can also explicitly include properties that pertain to a level of detail. Instances of classes represent the actual resource instances, the nouns representing the physical or logical resources in the environment. Instances have attributes and can take part in relationships.
For example, in a database management environment, items such as the database server, tables, and connections are Instances. Instances also include things that are not limited to being managed but which take part in the management process, such as users or business systems.
Out of the various objects in the CDM, Classes are the only ones in use to represent resource instances.
There are particular classes mentioned throughout the TADDM documentation that have particular meaning: All classes derive in some way from ModelObject. The ModelObject and ManagedElement classes are used interchangeably. The CDM supports specialization through single inheritance, although the use of interfaces gives the model some aspects of multiple inheritance. All classes are organized into a single-rooted, single inheritance hierarchy with the ModelObject class as the root.
Every class, with exception of ModelObject, specifies exactly one parent, and the child class inherits all characteristics of the parent class.
See the section on Naming instances for more information about naming rules for model objects. A persistent class is a class whose instances can be stored in a database, whereas instances of a non-persistent class cannot be stored in a database.
The only exception is when you query the attribute, "guid" of a ModelObject non-persistent classas in the following example: The attribute, "source", is a ModelObject, and the following queries return the same results: If the tag is not present for a given class, then it is a non-persistent class.
Examples of persistent classes: An attribute defines a particular property that is valid for a class. Each attribute has a particular meaning or semantic in terms of expected content. You can use the CDM to create data repositories that match the schema, and you can also transform your existing data into the CDM schema. Either way, the efficiency that you get from standardization can expedite and streamline whatever you do next with your data.
Who uses the Common Data Model? A variety of customers, partners, and products use the CDM, and all have the same goal of unifying data in a well-known form with semantic meaning.
These users are responsible for bringing data from a variety of systems to make it accessible for apps to use.

Historically, the work to build an app has been tightly tied with data integration, but with the CDM and the platforms that support it, the two can happen independently. These examples show how organizations use the CDM: In fact, many of the original business entities in the CDM came from Dynamics offerings, such as Dynamics for Sales and Dynamics for Marketing.
Industry verticals such as healthcare are working closely with Microsoft to extend the CDM to their specific business concepts, such as Patient and Care Plan through Industry Accelerators. That way, users can can share data and build services so partners can easily exchange data, create interoperable apps and services, and create quick analytics that are easy to share.
