A recent job advertisement caught my attention, because I thought I was already broadly familiar with all the major OSes and database engines:
Quote:
Mainframe Analyst/Programmers
We have a number of roles in Australian capital cities for Natural/Adabas analyst/programmers.
You must have at least 8 years experience in the Natural/Adabas space, be a self-starter, and have good communication skills.
Apparently (according to Wikipedia), ADABAS is an 'inverted list database... described as "Post-relational" but "Relational Like" in its characteristics' and frequently used in conjunction with NATURAL for access and plain-text output. Both are still developed and maintained by Software AG.
I would be grateful if other users would share their experiences working with ADABAS/NATURAL and how it compares to other database engines.
