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 create further elements, to cut, copy and paste the package, to change the name of the package, and to delete it. 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. Cut Cut the package to paste it elsewhere to the Implementation tree. Copy Copy the package to paste it elsewhere to the Implementation tree. Paste Paste the package elsewhere to the data model tree. Available if Copy or Cut option have been used before. Rename Change the package name. Delete Delete the package.
	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 create further elements, to cut, copy and paste the class, to change the name of the class, and to delete it. Menu Item Description Add Class Add a sub-class to the class. Add Interface Add an interface to the class. Add Property Add a property to the class. Add Operation Add an operation to the class. Cut Cut the class to paste it elsewhere to the API or Implementation folder. Copy Copy the class to paste it elsewhere to the API or Implementation folder. Paste Paste the class elsewhere to the API or Implementation folder. Available if Copy or Cut option have been used before. Rename Change the name of the class. Delete Delete the class.

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 operation
• activity operation
• action script operation

For detailed information on how to implement the different types of operations refer to the the above mentioned pages.

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 operation in a separate tab. If you have not yet selected an implementation, a dialog opens first, which allows you to select the desired implementation. Refer to Create Implementation for more information.

The context menu of an operation allows you to create further elements, to select and change the type of implementation of the operation and to open the implementation of the operation. Furthermore you can cut, copy and paste the operation, change the name of the operation, and delete it via this menu. Menu Item Description Add Parameter in Add an input parameter to the operation. Add Parameter out Add an output parameter to the operation. Add Parameter return Add a return parameter to the operation. Add Operation (Suboperation) Add a suboperation to the operation. Open (Implementation) Open the implementation of the selected operation in a separate tab. Available if the operation has an implementation, yet. Change (Implementation) Change the type of implementation or remove the implementation. Available if the operation has an implementation, yet. Create (Implementation) You can choose between three different types of implementation for your class operations: Mapping Diagram: Refer to Modeling Data Mapping for detailed information. Action Script: Refer to Using Action Script for detailed information. Activity Diagram: Refer to Modeling Activities for detailed information. Available if the operation has no implementation, yet. Cut Cut the operation to paste it elsewhere to the API or Implementation folder. Copy Copy the operation to paste it elsewhere to the API or Implementation folder. Paste Paste the operation elsewhere to the API or Implementation folder. Available if Copy or Cut option have been used before. Rename Change the name of the operation. Delete Delete the operation.

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).
Refer to Adding Parameters to Operations for information on how to create parameters.

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 create further elements and to change the name of the interface. Furthermore you can cut, copy and paste as well as delete the interface via this menu. Menu Item 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). Cut Cut the interface to paste it elsewhere to the API or Implementation folder. Copy Copy the interface to paste it elsewhere to the API or Implementation folder. Paste Paste the interface elsewhere to the API or Implementation folder. Available if Copy or Cut option have been used before. Rename Change the name of the interface. Delete Delete the interface.
