Data model extensions
Extensions used by the data model
On any data model, it is possible to specify some extensions to be used. These extensions will have the capacity to define additional features around the data model and to enrich the current data model after the publication by adding properties and constraints to the data model elements. Data model extensions are displayed in the navigation pane under the section 'Extensions'.
The following extensions are automatically enabled on new data models:
Some extensions are optional and defined in dedicated datasets. These extensions can be disabled or enabled through the user interface.
Optional data model extension can be disabled by selecting the action 'Disable extension' from the menu 
to the left of extension to disable.
Note
When disabling an extension its dedicated dataset is also deleted and it is not possible to recover it after its deletion
From the down arrow to the left of 'Extensions' entry in the navigation pane, you can enable an extension by selecting the action 'Enable an extension'. This option is only displayed if some extensions are available. When selecting this action a form displays the available data model extensions.
Once a data model extension is activated then it is displayed under the entry 'Extensions' in the navigation pane and can be edited as a regular dataset. That is, the configuration of an extension is embedded in a dedicated dataset that benefits of all EBX® features available on datasets.
Indexing and search strategies
This feature is documented in the chapter Search.
Toolbars
A toolbar allows to customize the buttons and menus that are displayed when viewing tables or records in a dataset. The customization of toolbars can be performed in the data model via the 'Configuration' section.
Add a toolbar from the Toolbars section of the navigation pane, by clicking on the arrow located to the right of [ All elements ], then selecting the Create toolbar option. Follow the creation wizard to create a toolbar. A toolbar defines the following information:
Name | Toolbar's name. The name of the toolbar must be unique in the context of the data model. That is, it is not allowed to create several toolbars with the same name. |
Label and description | Internationalized labels and descriptions to be displayed to end users. |
Default template | Allows to create a toolbar with the structure of a default toolbar. |
Locations | Specifies the locations where the toolbar can be used in associated datasets. |
Defining the structure of a toolbar
A toolbar can define the following elements:
Add one of these elements under a toolbar or to an existing element by clicking on the arrow located to the right of the existing element, and by selecting a creation option in the menu. Then, follow the creation wizard to create an element.
Action button
This type of element allows to associate an action to a button in a toolbar. The action will be triggered when the user clicks on the associated button in one of the toolbars. A Action button type element defines the following information:
Service | Defines the service that will be executed when the user clicks on the button. It is possible to select a built-in service, or a user service defined in a module or in the current data model. If the 'Web component' target is selected, the service will have to be declared as available as a web component for toolbars. |
Label and description | Internationalized labels and descriptions to be displayed to end users. |
Layout | Defines how this element will be displayed in datasets using the toolbar. It is possible to display: the icon only, the text only, text with the icon to the left or text with the icon to the right. |

Note
An element of the Menu button type can only be created under an element of the toolbar type.
Separator
This type of element allows to insert a separator in the form of spacing between two elements of a toolbar.
Note
An element of the Separator type can only be created under an element of the toolbar type.
Menu group
This type of element allows to define a group of elements in a menu. An element of the Menu group type defines the following information:
Label and description | Internationalized labels and descriptions to be displayed to end users. |
Group type | Specifies the type of menu group to create: |
Service group name | Specifies an existing group of services to reuse. A group is declared in a module and can include other groups of services. All services contained in this group will be displayed to end users in associated datasets. |
Menu builder name | Specifies the predefined menu content to assign to this menu group: |
Excluded services | Indicates the services to exclude from the group of reused services. These services will not be displayed to end users in associated datasets. |
Excluded service groups | Indicates the groups to exclude from the group of services to reuse. Services in excluded groups will not be displayed to end users in associated datasets. |
Filtering policy | In case of "Smart filtering", services that are configured in direct access, i.e. via an action button or an action menu item, will be removed from the automatic generation of this group. |
Note
An element of the Menu group type can only be created under the following elements:
Menu button
Sub menu item
Action menu item
This type of element allows to associate an action to a menu item in a toolbar. The action will be triggered when the user clicks on the corresponding item in a menu. An element of the Action menu item type defines the following information:
Label and description | Internationalized labels and descriptions to be displayed to end users. |
Service | Defines the service that will be executed when the user clicks on the button. It is possible to select a built-in service, or a user service defined in a module or in the current data model. If the 'Web component' target is selected, the service will have to be declared as available as a web component for toolbars. |
Note
An element of the Action menu item type can only be created under a Menu group type element.
Sub menu item
This type of element allows to add a sub menu to a toolbar menu. Un Sub menu item defines the following information:
Label and description | Internationalized labels and descriptions to be displayed to end users. |
Note
An element of the Sub menu item type can only be created under an element of the Menu group type.
Deleting elements
All the elements of a toolbar can be deleted from it by using the arrow located to the right of the element to be deleted.
If an element containing other elements is deleted, then the deletion is recursively performed on all elements located below the deleted element.
Duplicating existing elements
To duplicate an element, click on the arrow located to the right of the element to duplicate. Specify the name and properties of the duplicated element. All the source element properties are duplicated.
The duplicated element is added on the same level than the original element, in the final position. When an element containing other elements is duplicated, all the sub-elements are duplicated with their properties.
Moving elements
In order to move an element, click on the arrow and select the moving option to be used.
Associate with existing tables
To associate a toolbar with existing tables, click on the arrow located to the right of the toolbar and select the option Associate to tables. This service allows to set the toolbar has the default toolbar of several tables in one shot. To do so, specify the target locations of the toolbar and select the tables or complex data types, that define table properties, to be associated with the toolbar.
Exporting the toolbars
It is possible to export the toolbars defined in the model into an XML document. To do so, select the XML export option available in the Actions menu of the 'Toolbars' section. Follow the wizard to export the toolbars.
Note
A selection of toolbars can be exported by selecting in the 'Toolbars' section the toolbars to be exported and then by selecting the XML export option available in the Actions menu. The toolbars can also be exported by using the data model export service. It can be found in the Data model 'Actions' menu in the navigation pane.

Data services
It is possible to refer to tables in Data Service operations using unique names instead of their paths by defining suffixes for WSDL operations. A WSDL suffix is the association between a table path and a name.
To define a WSDL suffix through the user interface, create a new record in the 'Data services' table under the data model configuration in the navigation pane. A record of this table defines the following properties:
Table path | Specifies the path of the table in the current data model that is to be referred by the WSDL operation suffix. |
WSDL operation suffix | This name is used to suffix all the operation names of the concerned table. If undefined for a given table, the last element of the table path is used instead. This name must be unique in the context of this data model. |

Replication of data to relational tables
In any data model, it is possible to define replication units for data in the repository to be mirrored to dedicated tables in the relational database. These tables then enable direct access to the data by SQL requests and views.
To define a replication unit through the user interface, create a new record in the 'Replications' table under the extensions' section in the navigation pane. Each replication unit record is associated with a particular dataset in a given dataspace. A single replication unit can cover multiple tables, as long as they are in the same dataset. A replication unit defines the following information:
Name | Name of the replication unit. This name identifies a replication unit in the current data model. It must be unique. |
Dataspace | Specifies the dataspace relevant to this replication unit. It cannot be a snapshot. |
Dataset | Specifies the dataset relevant to this replication unit. |
Refresh policy | Specifies the data synchronization policy. The possible policies are:
|
Tables | Specifies the tables in the data model to be replicated in the database. Table path: Specifies the path of the table in the current data model that is to be replicated to the database. Table name in database: Specifies the name of the table in the database to which the data will be replicated. This name must be unique amongst all replications units. |
Aggregated lists | Specifies the properties of the aggregated lists in the table that are replicated in the database. Path: Specifies the path of the aggregated list in the table that is to be replicated to the database. Table name in database: Specifies the name of the table in the database to which the data of the aggregated list will be replicated. This name must be unique amongst all replications units. |
