As your data file becomes larger, and as you add more 4D Client or Web connections, optimization becomes even more important. The purpose of this two-part Technical Note is to give you some insight into how you can optimize the handling of your record selections in 4D. In Part 1, we discussed the organization of a 4D data file, and how it uses disk space and memory. In Part 2, we examine the concepts of the current record, the current selection, and named selections in 4D and discuss principles that will help you to optimize performance when you have large data files and/or large numbers of users.
