Data Collections are sets of tabular data that are maintained in memory by AppBoard. The contents of the Data Collections can be manipulated through filtering, grouping, sorting and pivoting features available in the Data Collections Wizard. Associations can also be established between collections to support the visualization of multiple data sets.

Reviewing Data Collections

Use these instructions to view a list of all Data Collections that are available in the system:

1. Click "Data Collections" in the left side tool pallette.
2. Data Collections are listed in a data grid in the first page.
3. To preview the data in a Data Collection, click the blue preview button in the rightmost column.

Filtering Data Collections

For general information about the various options for filtering Data Collections in AppBoard, see Filtering Data Collections.

Adding a Data Collection

Use these instructions to create a new Data Collection:

1. Click Data Collections link in the left side tool palette.
2. Click Add button at the bottom of the page to launch the Data Collections Wizard.
3. On the Configure panel, enter the following:
   • Data Collection Name - Provide a unique name for the Data Collection.
   • Data Source - Select the Data Source that will be used for the Data Collection.
   • Options - Check one or more of the following options:
     1. Filter - Provides an interface for adding server-side filters to the Data Collection (See Server-Side Filters and Simple Property Comparison for more information).
     2. Server Side Sort - Allows you to specify the default sort order in which the Data Collection is displayed using these options:
        • Server Side Sort - Select the field from the Data Source by which the Data Collection will be sorted.
        • Order (the box to the right) - Select either Ascending or Descending.
     3. Limit Row Count - Allows you to limit the number of rows returned by the server for this Data Collection, using the Server Side Row Limit box.
     4. Polling - Provides the option of setting a Polling Interval. This is the number of seconds to wait before the client will fetch the latest data from the server cache. For example, if this is set to 30, every 30 seconds AppBoard will refresh the Data Collection to have the latest data from the server. The minimum polling interval value is 5 seconds and the maximum value is 3600 seconds (one hour). Note: To maximize performance, Data Collections are only polled when one or more of the Widgets that uses that Data Collection is in the foreground display.
   • Click the Next button.
4. On the Client Side Filter panel, add one or more Client Side Filter Rules as needed (See Client-Side Filters for more information).
5. Click "Finish" to create the Data Collection.
