Database Block Overview tab

The Overview tab of a Database Block displays the label of the Database Block instance in a read/write mode. It also displays information specific to the instance in a read-only mode. Buttons in the Overview tab enable you to access the other tabs of the editor in which you can modify or complete this information.

Description of the tab

Three sections are not tabs themselves. They are displayed in the Overview tab only: Alerts and Action Items, General information, and Generation parameters definition (on some entities).

All the other sections provide links to the corresponding editor tabs.

If information is displayed in each section, you can do either of the following tasks:
  • Click it if it is displayed as a link. You automatically switch to where the information has been specified.
  • Or click the More button to switch to the corresponding tab.

If no information is displayed in the section, click the sym located in front of the section name. It gives you access to the More button. Click it to access the corresponding tab.

The sections of the tab

Alerts and Action Items
Any problem related to the current instance (for example, if the instance calls another instance that has been deleted) is displayed here as a link. If you click this link, you automatically switch to the Problems view, where the line corresponding to the error is highlighted. The error is clearly explained and you can correct it.
General information displays the following fields:
Work context
The work context is the project from which you have opened the editor of the current instance. This project constitutes the starting point for the resolution of the dynamic links and references between the instances contained in the various projects of the location. The projects hierarchy declared in the design build path is explored in an upward direction.

If you click Hierarchy, you can see a partial view of the design build path. In this view, the project which constitutes the work context is the lowest project of the hierarchy.

More information can be found in the following topics: The work context and The design build path.

Name
The instance name is displayed in read-only mode. Ut is entered when the instance is created, and it cannot be modified later.
Label
Enter the label, which identifies the new instance. It constitutes a search criterion for a subsequent search.
Definition
This section shows the:Block type specified in the.Definition tab of the Program. It also shows the Generated skeleton language, selected in the Definition tab of the Library where the Block is defined.

Click the More button to access the Definition tab.

Generation parameters definition
Generation parameters are specified in Libraries. These parameters are related to the adaptation to the operating system in use.

So the current instance is associated with the generation parameters indicated in the Library displayed here. You can click Change to select another Library.

The other sections of the Overview tab display the information, if any, entered in the corresponding tabs:
  • The -Dx Lines section (with x = C, H, or R according to the Bloc type) gives access to the Description tab, whose contents are specific to each Bloc type.
  • The -G Lines section gives access to the -G Lines tab, where you can enter comment, generation elements and options on the Database Block.
  • The Keywords section displays the Database Block keywords.
