RDB relational database management system
RDB is a fast, portable, relational database management system without arbitrary limits, (other than memory and processor speed) that runs under, and interacts with, the UNIX Operating system.

The tools are accessed using the UNIX shell and are largely developed using Perl programming language.

RDB data file format
RDB data files are text files that are composed of:


 * 1) Zero or more comment lines
 * 2) A line of tab-delimited column names
 * 3) a line of tab-delimited column widths (with optional formatting codes)
 * 4) zero or more lines of tab-delimited data.

RDB files are normally named with an .rdb file name extension.

This simple, self-documenting format has been adopted as an output file format outside of its use in RDB. For example, the tab-delimited export file format used by the USGS's National Water Information System-Web
