Has anyone modified an SQL package to interface to a proprietary file system? My idea is to buy an SQL package and remove the modules containing the I/O calls to the UNIX file system, replacing them with calls to a proprietary file manager. Hopefully, this can be done without buying source rights but instead an unlinked object library. I would appreciate any insights into this (not whether it is desirable!). The 'typical' SQL package incorporates a file system with indexes stored as B-Trees and records stored 'end-to-end'. I would keep the B-tree structure but would replace the file in which the data record is stored. Since our file system is rather 'unique', there would have to be conversion of 'fields' from our format to the format expected by the SQL package.
