Controlling Incremental Updates
The first time you run Analyzer against a database, every design element is analyzed (unless you excluded some of them on the Design Notes tab). When you run Analyzer subsequent times, select the Incremental update check box to analyze and update the documents for only those design elements that have changed since Analyzer was last run against them.
Clear the Incremental update check box to analyze every design element and update every document even if it has not changed. This feature allows you to change the title of a database and then update the design documentation and propagate the new title into other design elements.
