| What is RXDbase. The main goal was to provide a simple yet efficient database table class object which would have the following features: Fixed length fields (this feat may be removed by popular demand). ISAM and B+Tree indexing. Rexx string-oriented. (non-typed fields) Easy to use. Exploitable from NetRexx and Java seamlessly. Could read and write both local and remote db tables. The result is that four classes were generated: RXDbase is the local storage, NetRexx friendly class. RXDBClient is the remote storage, NetRexx friendly class. JRXDBase is the local storage, Java friendly class. JRXDBClient is the remote storage, Java friendly class. A fifth object, BPlusTree, has been added since then; it is a B+Tree implementation specifically designed for persistent, disk-based trees, with pattern-matching queries and several other features. You can of course use it in your programs as long as you have a valid MaxBase developer license.
