The MINGL database system is an integrated set of tools which provides a means of collecting and managing diagnostic data and transport code results from TFTR. An interactive menu‐driven format allows users to collect scalar and profile data from various data sources into shareable INGRES databases. LOCUS and INGRES/QUEL/SQL interfaces make it easy to browse, select, compare, and display the data in one of several formats. Utilities exist for managing the individual data sets and restricting their accessibility, for indexing the tables by author, and for maintaining a table of contents for an entire database. The modularity of the system allows automated database‐server applications for between‐shot analysis and display.
