If you want to create your own data model within the Designer, you need to create a Service first. In the Service panel resides a folder Implementation where you can add your own data model to.

Implementation Elements

To model your own data structures, you have the following elements available:

Each element of the Implementation folder has a context menu and quick actions. The context menu contains options to create new elements to the selected element, and to edit the current element. Via the quick actions, you can access the most used menu items directly with a single click.

Package

A package is like a directory for the file system. It is used to group executable data model elements. Packages can have any depth of nesting: To structure your work, you can create packages within packages.
Also, packages define a sort of namespace to the contained elements. The name of the package is part of the element path, e.g. Package1.Class is different from Package2.Class.

	The quick actions of a package allow for the creation of packages, classes and interfaces. Quick Action Description Add another package within the existing package. Add a class to the package. Add an interface to the package.
	The context menu of a package allows you to change the name of the package, and to create further elements. Menu Item Description Add Package Add another package within the existing package. Add Class Add a class to the package. Add Interface Add an interface to the package. Edit Package Change the package name. Delete Package Delete the package. Copy Item Copy the package to paste it elsewhere to the Implementation tree. Cut Item Cut the package to paste it elsewhere to the Implementation tree. Paste Item Paste the package elsewhere to the data model tree. Available if Copy Item or Cut Item option have been used before.
	Package Message is a generated package that contains all classes that are related to the forms you have already created to your Forms folder. This package is locked - you cannot change the generated form classes.

Class

A class is an aggregation of properties and operations that describes a complex data type from which objects can be created.

The quick actions of a class allow for the creation of properties as well as operations with different types of implementation. Quick Action Description Add a mapping operation to the class. Add an action script operation to the class. Add an activity operation to the class. Add an operation to the class. The implementation is to be defined later. Add a property to the class.

The context menu of a class allows you to change the name of the class, and to create further elements. Menu Item Description Add Property Add a property to the class. Add Operation Add an operation to the class. Edit Class Change the name of the class. Delete Class Delete the class. Copy Item Copy the class to paste it elsewhere to the data model tree. Cut Item Cut the class to paste it elsewhere to the data model tree. Paste Item Paste the class elsewhere to the data model tree. Available if Copy Item or Cut Item option have been used before.

Property

Properties are data fields that describe the structure of the class.

Operation

An operation adds behavior to a class or interface. The behavior describes how to process the data given by the parameters. In the context of the Designer, you can implement operations as mapping, action script or activity.

The quick actions of an operation allow for the creation of parameters with different directions, and to jump to the implementation of the operation. Quick Action Description Add an input parameter to the operation. Add an output parameter to the operation. Add a return parameter to the operation. Open the implementation of the selected operation in a separate tab.

The context menu of an operation allows you to change the name of the operation, and to create further elements. Menu Item Description Add Parameter Add a parameter to the operation. See below for more information. Create Implementation You can choose between two different types of implementation for your class operations: Mapping Diagram: Go to Modeling Data Mapping for detailed information. Action Script: Go to Using Action Script for detailed information. Activity Diagram: Go to Modeling Activities for detailed information. Available if the operation has no implementation, yet. Open Implementation Open the implementation of the selected operation in a separate tab. Edit Operation Change the name of the operation. Delete Operation Delete the operation. Copy Item Copy the operation to paste it elsewhere to the data model tree. Cut Item Cut the operation to paste it elsewhere to the data model tree. Paste Item Paste the operation elsewhere to the data model tree. Available if Copy Item or Cut Item option have been used before.

Parameter

Operations can have parameters that define the input and output objects. Operation parameters can be of simple type (Base Types) or of complex type (class or interface).

Interface

In contrast to a class, an interface has no properties nor implementations. Interfaces are used to define common operations of multiple classes, and then derive from that interface.
Operations of interfaces do not have an implementation but only define the signature (parameters and types).

The quick action of an interface allows for the creation of operations. Quick Action Description Add an operation to the interface. Operations of interfaces have no implementation, they only describe the signature of the operation.

The Interface context menu allows you to edit your interface and to create further elements. Option Description Add Class Add a class or sub-class to the interface. Classes within interfaces can be nested. Add Interface Add another interface to the interface. Interfaces can be nested. Add Operation Add an operation to the interface. Operations of interfaces do not have an implementation but only define the signature (parameters and types). Edit Interface Change the name of the interface. Delete Interface Delete the interface. Copy Item Copy the interface to paste it elsewhere to the data model tree. Cut Item Cut the interface to paste it elsewhere to the data model tree. Paste Item Paste the interface elsewhere to the data model tree. Available when Copy Item or Cut Item option have been used before.
