Database Views

Whilst viewing Data Structures in the Database View you are able to use the Right Click Function to navigate to other parts of the treeview structure.

Right Click Function

The Right Click function in the Database View is context sensitive and will display options based upon the currently selected item in the left hand treeview. Generally the right click functionality is only available when a specific data structure has been selected.

Options include:-

Option	Action
Go to Description Information	Changes your selection to the Structure item in the Description File View for the currently selected Structure
Go to Control Information	Changes your selection to the Structure item in the Control File View for the currently selected Structure
Go to Data Information	Changes your selection to the Structure item in the Data Information View for the currently selected Structure
Go to Data View	Changes your selection to the Structure item in the Data View for the currently selected Structure
Record Format	This initiates the Record Format dialogue for the currently selected Structure
Key Format	This initiates the Key Format dialogue for the currently selected Structure
Expand Tree	This will expand the currently selected item to display all of the sub items in the treeview
Collapse Tree	This will collapse the currently selected item to hide all of the sub items in the treeview
Collapse Parent	This will collapse the parent item of the currently selected item to hide all of the sub items of the that parent item

Description File Information

The Description file is the machine readable version of the DASDL file and therefore holds all of the static definition of the database. This includes the global attributes of the database, structure definitions, data items and attributes.

The Description File is primarily used for compiling software which will run against the database. It does not form part of the running database.

Below is a summary of the items that can be found under the Description File in the treeview.

Control File Information

The Control File is the file used by the run time database to hold global and structure information. The information in the control file is dynamic and will change as the database is active. The information in the batch file is a snapshot of this dynamic information at the time of capture.

Below is a summary of the items that can be found under the Control File in the treeview.

Control File

	Control File Information	This view shows the Database Summary for the Database
	Global Attributes	This view shows the attributes that have been defined Globally for the database.
	Options	This view shows the Boolean options which may be set in the database to control the way if globally functions
	Dynamic Parameters	This view shows the dynamic parameter values which may be set in the database to control the way it globally functions
	Audit Attributes	This view shows the definitions of the Audit trail for the database, this includes both primary and secondary audit attributes.

	Remote Database	This view shows the definitions of the Remote Database settings for the database.
	Structures	When expanded this item displays all of the Data Structures in the database
	Dataset	This view shows a Control File attribute summary for the Dataset
	Set	This view shows a Control File attribute summary for the Set

Data Files Information

When a data file structure is selected in the left hand treeview data about the structure is displayed on the right hand side. The data displayed is context sensitive and will show the data suitable to the selection made. By selecting the Data Display option graphics you may view other data about the structure.

Below is a summary of the items that can be found under the Control File in the treeview.

Icon	Item	Description
	Data Files Information	This view shows the Database Summary for the Database
	Structure	The Structure view lists the Dataset and associated Sets that make up the complete structure. This view shows a Dataset attribute summary for the Dataset
	Dataset	This view shows a Dataset attribute summary for the Dataset
	View Dataset Data View	View Dataset Data View
	Set	This view shows a Set attribute summary for the Set
	View Set Data View	View Set Data View

Data View

The Data View allows you to view the internal formats of the Data Structures. This is achieved through a combination of captured Batch File data and data captured real time through the Named Pipe interface.

Only one structure may be viewed in the Data View format at one time. Once you have selected to view a structure in the Data View format you are able to remove the structure by selecting the structure and clicking on the delete button on the toolbar.
