Main Areas of the Design Studio¶
The administration-related menus and dialogs are not currently available on the Design Studio but future updates will extend the current options to progressively add them.
The Design studio has three main areas: the menu, the Server Explorer and the Work Space.
The menu bar has the following menus:
File: it has the following submenus:
New: it has submenus to create any type of element: folders, data sources, views, etc.
Export database: to export the metadata of a database or a specific element of it.
Export: to export the metadata of the entire Server.
Import: to import the VQL statements stored in a file.
The section Exporting and Importing the Server Metadata explains how to use the dialogs “Export database”, “Export” and “Import”.
Extension management: to import extensions and drivers to the server. I.e. jar files containing custom functions, custom wrappers…; the JDBC drivers of databases that are not included with the Denodo Platform.
Refresh: if there have been changes in the metadata of the Server, refresh the Tool to reflect these changes.
Close all tabs: easy way to close all opened tabs in the Work Space.
Disconnect: disconnects the Administration Tool from Virtual DataPort.
Using the Design Studio VQL Shell: shell to execute SQL and VQL statements.
Trace viewer: tool to load information about the execution of a query that was stored in a zip file using the Save button of the tab Query Results.
Design Studio Query Monitor: tool to monitor the queries that the Server is currently executing.
OAuth credentials wizards: contains two submenus to open the OAuth 1.0a wizard and the OAuth 2.0 wizard. See more about these wizards in the section OAuth Authentication.
Admin Tool preferences: contains submenus to configure several aspects of the Administration Tool.
Help has sub-menus to access the on-line help.
User Logout: disconnects the Design Studio from Virtual DataPort.
The panel of the left side is called Server Explorer. It lists all the databases of Virtual DataPort; and for each database, its data sources, base views, derived views, stored procedures, etc. These elements can be organized in Folders so they can be found easily.
To open the contextual menu over a element of the Server Explorer, hover the mouse over the desired element (database, view, folder, etc.) and a three dots button will show up on the right side of the element. Click on that button to open the contextual menu.
Using the Server Explorer, you can do, among others, the following actions:
Create new elements: click on the three dots of a database or a folder, click New and then, select the desired element of the submenu.
Rename an element: click on the three dots of the element and click Rename.
Delete an element: click on the three dots of the element and click Drop.
Copy and Paste an element: click on the three dots of the element and click Copy. Then, click on the three dots of the target folder and then, Paste. As there cannot be two elements with the same name, even if they are in different folders, you will have to provide a name for the new element.
Move an element to another folder: drag an element and drop it into another folder. You cannot move an element between two databases.
See the properties of an element: click on the three dots of the element and click Properties. In this dialog, you can see information about the selected element such as owner, description, date of creation and last modification, etc.
Show a view in the GraphQL service: click on the three dots of the view and click Open GraphQL service.
Show a view in the OData service: click on the three dots of the view and click Open OData service.
Expand and collapse all the nodes of the Server Explorer: click on the three dots of the database or a folder and click Expand all or Collapse all.
If you click Discover associations (only applies to JDBC base views), the Server will analyze if in the database of the JDBC data source, there are foreign key constraints between the tables of the base views of this data source. If there are, the Tool will show a dialog that will allow you to create associations that mirror these foreign key constraints. The process of discovering associations works in the same way as when you discover the associations during the creation of JDBC base views (described in the section Creating Base Views from a JDBC Data Source). However, if an association is already defined, the Tool will not list it.
It is possible to perform actions over multiple elements at the same time. To do that, just hold the Ctrl key and click on the elements you want to select. A multiple selection menu will show up at the bottom of the server explorer with the actions available.
You can create a view from several views and, delete or move several elements at the same time by selecting these elements and performing the desired action. For example, to delete two views at the same do the following:
Hold the Ctrl key.
Click on these two views.
In the multiple selection menu, click on More and then Drop.
Above the Server Explorer, you can find the Quick Search. Type the name of the element you are looking for or select the type of that element.
The “Work Space” is the main part of the Tool and it is where all the dialogs are displayed. You can open several elements at once. They will be opened in tabs. Tabs are fixed and can not be moved out of the “work Space” area.
