It's built up as a collection of tools, as opposed to a single huge program. The usual operations for doing row, column-extraction and joins of relational-style tables are all there, along with a plotting program and some plot(1) filters (including one for X11). All tables are ascii files. In one sense, these utilities are simply an extension of awk, join, cut, cat etc, which allows named referencing to columns. Used together, these tools allow you to do anything you can do with other dmbs's - sometimes slower and sometimes faster. This sounds like \rdb as documented in the relatively new book "UNIX Relational Database Management: Application Development in the UNIX Environment" by Rod Manis, Evan Schaffer, and Robert Jorgensen. A good book on how to development an application system using the Unix shell language as a 4GL environment. The book discusses building a relational database system using ASCII files and standard(?) UNIX commands. It also shows many of the shells that were built to support this idea. An interesting (and somewhat overlooked) book. -- =================================================================== David Masterson Consilium, Inc. uunet!cimshop!davidm Mt.
