Use Data Explorer to test, prototype, perform back-office data maintenance, and view data for existing systems–regardless of their architecture. You can explore data, prepare use cases, and make repairs to your API using Data Explorer.
You can also create and manage a schema using Data Explorer. For more information about how to create and manage schemas using Data Explorer, see Database Creation.
Data Explorer is a self-contained service that is layered over API Creator.

Data Explorer Key Services
Data Explorer provides the following key services:
- Multi-table use interfacederived from your parent/child relationships, including:
- List/form view.You can view your information in the Main Grid and in the Form.
- Master/Detail presentation.View child objects for a parent (for example, products for category or orders of customer).
- Drill-down navigation.View related data (for example, Orders for Product or SalesRep for Order).
- Automatic joins.(For example, show product name, not product number.)For more information about automatic joins, see Automatic Joins.
- Filtering on multiple fields.Includes paginated scrolling (subject to row/column security).Fields represent the columns in your database. The termfieldis used to stay within the metaphor of applications and screens, and not database terminology.
- Row-sharing.Send the current row in the Form to colleagues.
- Formatting.For example, currency.
- Update services.
- Updatable grids.You can update your information in the Main Grid, in the Form, and in the Child Grid.
- Lookups.Relate a child to a parent (for example, Company Name for Product).
- Logic and security enforcement.Reactive logic enforces your logic and security.For more information about how reactive logic and security work in Data Explorer, see Logic Demo.
- Author Mode.Control which attributes are displayed, grouped, and formatted, and skinning.For more information about how to customize the appearance of behavior of your forms, see Author Mode.
Data Explorer as a Back-Office Interface
- Back-office database maintenance applications
- Schema exploration
- Data administration
For new systems or new components, integration with reactive logic means you have a solid back-office interface that enforces your business logic and security, working in conjunction with REST-based mobile and web apps. Data Explorer provides an automated UI for the entities (tables or views) within the data source. In API Creator and Data Explorer, database tables and database views are collectively referred to as database entities. You can query, browse, and update data in the Main Grid and Form for back-office use.
For more information about the Data Explorer components, including the Main Grid and the Form, see the Data Explorer Components section.
Data Explorer is Schema Driven
Data Explorer implements a number of heuristics based on the relationships in your database (by way of foreign keys):
- As you create child entities, a relationship between the child and the parent is created. This child relationship is represented as a tab in the Child Grid.
- Data Explorer uses each parent relationship for lookups and navigations.
For more information about the heuristic
CA Live API Creatoruses to introspect target (child) for an entity-type method that returns the type of the source (parent), see InsertIntoFrom System Method.
Many databases employ surrogate keys. For example, the Business Logic API sample identifies a product by
product_number, instead of a name like hammer or shovel. These basic heuristics produce a usable result for child entities containing foreign keys to products, such as Lineitem. It is not interesting to see a list of ten part-1'2, five part-2's, and so forth. You want to see the name of the parent row.
When you identify parents by a numeric key, Data Explorer selects the first text fields to be the
UserKey, a field likely to be a more recognizable name. You can reselect the keys when the heuristic makes the wrong choice. For these joins, you can select parent and view parent.

Data Explorer Components
Data Explorer is comprised of the following components:
- The Main Grid (or the REST Log)The Main Grid is a tabular list of searchable rows. Each row in the Main Grid represents a record in the database.
- The FormThe Form is the scalar version of the selected row in the Main Grid. Each field represents a column in your database.
- The Child Grid.The Child Grid includes tabs based on child relationships.
Together, the Form and the Child Grid are the children linked by way of relationships. These relationships are defined in the database (the foreign key) or you can define them using API Creator (virtual foreign keys). The Form and the Child Grid are often called a Master/Detail form.
By default, the Main Grid, the Form, and the Child Grid components are in view. You can choose to view your information in Data Explorer using a combination of these components. On the toolbar, click the windows/panel menu and select your preferred layout. The following image shows the Data Explorer components in its default layout:
Access an Endpoint
You can access your database entities and resources using Data Explorer. From the toolbar, select
Resourcesfrom the endpoint type drop-down. By default, entities are in view and
For more information about how to toggle between tables, including information about the endpoint type drop-down in the Main Grid, see Author Mode.
Call Functions on Tables from Data Explorer
You can call functions associated to tables in Data Explorer. The last function you call is remembered in your Data Explorer session
- The function is a resource-oriented function. It is associated to the table on which you want to call your function.For more information about how to associate functions to tables, see Manage Functions.
- You have permissions to call the function.For more information about how to set function-level permissions for roles, see Role-Based Endpoint Access.
- On the toolbar, selectEntitiesas the endpoint type from the endpoint type drop-down and then select the entity on which you want to call your function from the endpoints drop-down. For example, Employee.
- In the Main Grid, select the row for which you want to call the function.
- In the Form, select the function from the functions drop-down. For example, giveRaise.The functions dialog appears. The following image shows this drop-down:
- If you have defined required parameters for the function, enter values for the required parameters and then clickSubmit.The response displays in the dialog.
The function is called on the selected row in the table. If the function contains logic that updates the row, the table row is updated. The Form is updated.
Move or Scroll Through Information
You can scroll through information and move between fields and between rows using the arrow keys, the Tab key on the keyboard, or the mouse. When you click a field in the Main Grid, the field becomes active and the row is selected.
You can update information in the Main Grid, in the Form, and in the Child Grid. For example, in the Main Grid, you can select fields within a row and edit the value or you can delete a row.
If the field is a parent field (indicated by an up arrow), you update the information by double-clicking the field.
Computed fields are read-only.
Save Changes to Rows and Delete Rows
You can save the changes you make to fields and rows in the Main Grid or to the current row in the Form by clicking
Saveon the toolbar.
To delete a row:
- Select the row you want to delete in the Main Grid.
- Mark the row for deletion (by selecting the row and clicking theX).
- Save your changes.
The row is deleted.
Revert your Changes
Revert changes before you save them by clicking
Undoon the toolbar.
You can create new rows in the Main Grid, Form, or Child Grid.
To create a new row in the Main Grid, click
Inserton the Form toolbar or on the Main Grid toolbar.
To create a new row in the Child Grid, click
Inserton the Main Grid toolbar.
Filter the Main Grid
You can filter the fields in the Main Grid to narrow the records displayed.
- Click the filter field down arrow on the Main Grid toolbar.The filter window appears.
- Choose the field by which to filter.
- Enter the value by which to filter. If the field is numeric or float data type, you can use the less than (<), the greater than (>), the less than and equal to (=<), and the greater than and equal to (>=) operators. If the field is boolean data type, you can search by true (T) or field (F). You can filter by null and not-null field values by choosing the Is Null or Not Null option.
- To search by an additional field, click the plus (+) symbol to filter by another field.
- Press the Enter key on your keyboard or click the Search icon.
The records in the Main Grid are filtered.
Return the Next Set of Rows
Return the next set of rows in the Main Grid or Child Grid by clicking
Fetch Moreon the Main Grid toolbar.
The number of rows returned to the Main Grid are controlled by pagination settings.
For more information about how to control the pagination settings, see API Properties.
You can navigate to related information using Data Explorer, such as moving from a customer and list of orders to an order with a list of items, or from an orders' item to the referenced product.
Navigation is based on foreign keys. If your database does not have defined foreign keys, you can add virtual foreign keys.
For more information about how to add virtual foreign keys, see Integrate Multiple Databases.
View Results of REST API Calls
You can see how REST and system-defined filters work by viewing the REST Log. The REST Log shows you the results of all the REST API calls made to the API Server connected to this session.
You can toggle between viewing the REST Log or the Main Grid. By default, the Main Grid is in view. On the toolbar, click the windows/panel menu and select
REST Log. The following image shows the toggle options and the REST Log:
Place Rows in the Form
You can place a row (for example, Order Details in the Child Grid) in the Form by selecting it and clicking
Zoomon the Child Grid toolbar. You can place the parent (view parent) in the Form (for example, Product) by clicking the triangle in the Child Grid.
Select a Parent
You can open the dialog to select, or look up, a parent (select parent) by double-clicking the parent in the Child Grid (for example, the product name).
Move a Row as Focus Table in the Main Grid
Move a row in the Child Grid as the main focus table in the Main Grid by clicking
Focus Tableon the Child Grid toolbar. You can also view a table in the Main Grid by selecting the table from the endpoint type drop-down on the Main Grid toolbar.
