Indexing Saved Data in Crystal Info 7.5 - Performance Gains
Not only does the Info Report Designer for Crystal Info 7.5 provide the report-processing power of Crystal Reports 8; it also enables you to increase the performance of your reports by indexing the saved data. When you create a Saved Data Index on a particular field, you enable Crystal Reports to filter on that field much more efficiently. In particular, you will achieve considerable performance gains - especially in your larger reports - by indexing fields that are referred to by row restriction formulas, Open Info Server Plug-Ins, or record selection formulas. This document outlines the workings of Saved Data Indexes and provides guidelines to follow when choosing fields to index.
