The c-treeDB API record management hides from the user all the complexities of maintaining a generic record buffer for tables. While fixed-length records may be easier to implement and maintain, variable-length records present a greater challenge for the developer.
When a table contains variable-length records, each record read may require buffers of different sizes. The c-treeDB record manager performs the function of expanding and shrinking record buffers to deal with the necessities of variable-length records. The FairCom DB ISAM API also requires different API calls for fixed-length and variable-length records, but the c-treeDB presents to the user one common API that deals with both fixed- and variable-length records.
Only the application architecture and system resources limit the number of c-treeDB record buffers associated with a table.
