FairCom Database Engine Partitioned Files

Understanding FairCom's Partitioned File and FILESET Technologies

FairCom DB offers many valuable—and, in many cases, unique—features aimed at our goal of making it easy for developers to create highly efficient applications based on c-tree technology. Two of these technologies address the issue of searching and maintaining large numbers of files: Partitioned Files and FILESETs. Both of these features simplify operations by making a large number of files appear as a single file to your application.

This paper compares these technologies. The following questions are examined:

• How do Partition Files compare to FILESETs?
• How does the Host File appear to the application?
• Can we perform Full-Text Search queries on a Host File?
• Can we operate on a single Member File independently?
• Can we do a File Block on an individual Member File?
• Is it possible to add extra user fields to an individual Member File?

Before answering those questions, an overview and comparison of the two technologies is presented:

• How Do Partition Files Compare to FILESETs?
