Oracle Corporation, a leader in the RDBMS field, is one of the two largest software companies in the world (like the other, Microsoft, a small fraction of its revenue comes from hardware product sales). Oracle has a corporate reputation for being combative, high-priced, enterprise-oriented, aggressive in its sales orientation to the point of occasional criminal investigation, and generally successful.

Oracle itself is a major user of Tcl. Several administrative utilities are Tk products. Oracle Enterprise Manager is crucial to ...

LV: Note that Oracle is now at version 11. Somewhere around version 10, they quit shipping a tcl component, but apparently still have some vestiges of tcl references in some of the materials. This is going to go away...

OMB Plus is a flexible, high-level command line metadata access tool for Oracle Warehouse Builder. OMB Plus is an extension of the Tcl programming language.

Transaction Control Language?

escargo 2007-08-21: The issue is muddied somewhat because Oracle also has a Transaction Control Language (so it's also abbreviated as TCL). (See

EMJ Well, no it doesn't, really. That reference is only a short note about the statements used to control transactions in SQL or PL/SQL, i.e. transaction control language with no capitals! There is no specific language involved. I consider the section heading Transaction Control Language (TCL) Statements to be a documentation bug and I intend to raise it as such - the abbreviation should not be there. This is the only such use of it in the entire Oracle documentation set.

escargo: I certainly don't mind if it's clarified, but searching through Oracle on-line docs for the right Tcl gets just a little harder when there is a clash like that.
