A Data Extract is a local file containing data extracted from a Data Source. Data Extracts allow sharing Workbooks in an offline fashion so that whoever opens the Workbook does not need to be directly connected to a database server as a datasource. Data Extract files have the file extension .vize and will get contained in Packaged Workbooks (.vizx files) when exporting or saving as Packaged Workbook files. Data Sources that use Extracts have icons that contain a blue cylinder.

1. Right-click on the data source and choose [Extract Data].
2. You will be prompted to save your Extract and give it a name.
3. The icon in your Data Pane will change to include a blue cylinder indicating it now uses an Extract.
Right-click on this Data Source in the Data Pane and notice the checkmark by [Use Extract], indicating it is currently in use.
Extracts are immediately put to use when they are created and they are not saved with the Workbook until you save. Reopening a Workbook without saving an Extract means you'll be using the original Data Source.
...
Once an extract is created you can view its properties by right-clicking on it and selecting [Extract > Properties].
Extract Properties include
- Data Source - The name of the Data Source used to generate the Extract.
- Location - Where the Data Extract (.vize file) resides.
- Query - The statement executed to retrieve the data from the server that created the extract.
- Max Results - The maximum number of rows set to be retrieved by the query as indicated in the Query Analyzer's Max Results form.
