DBMS acquisitions

Recently I expressed doubts about Actian’s DBMS-conglomerate growth strategy. For context, perhaps I should review other DBMS vendors’ acquisition strategies in the past. Some — quite a few — worked out well; others — including many too minor to list — did not.

In the pre-relational days, it was common practice to buy products that hadn’t succeeded yet, and grow with them. Often these were programs written at enterprises, rather than third-party packages. Most of Cullinet’s product line, including its flagship DBMS IDMS, was came into the company that way. ADR, if memory serves, acquired the tiny vendor who created DATACOM/DB.

Then things slowed down. A Canadian insurance company oddly bought Computer Corporation of America, to utter non-success. (At least I got an investment banking finder’s fee on the deal.) Computer Associates, which did brilliantly in acquiring computer operations software, had a much rockier time with DBMS. It acquired Cullinet, Applied Data Research, and ASK/Ingres — among others — and didn’t have much growth or other joy with any of them.

Indeed, Ingres has been acquired three times, and hasn’t accomplished much for any of the acquirers (ASK, Computer Associates, Actian).

I used to think that Oracle’s acquisition of RDB provided key pieces of what became Oracle’s own extensibility technology. Andy Mendelsohn, however, disputed this vehemently — at least by his standards of vehemence — and his sources are better than mine. Rather, I now believe as I wrote in 2011:

… while Oracle’s track record with standalone DBMS acquisitions is admirable (DEC RDB, MySQL, etc.), Oracle’s track record of integrating DBMS acquisitions into the Oracle product itself is not so good. (Express? Essbase? The text product line? None of that has gone particularly well.)

Experiences were similar for some other relational DBMS pioneers.  Read more

Why Michael Stonebraker matters

My deal when I blogged at Computerworld was that I could reuse my stuff if I linked to them. Below is the meat of a post about Michael Stonebraker I made in May, 2005.

Edit: There’s now a whole Michael Stonebraker section on DBMS2.

I’m probably going to mention Mike Stonebraker’s name in one or more other blog entries soon, and not necessarily in the context of always agreeing with him. So I’d like to take a moment to point out that he’s the greatest living contributor to database technology, and this may even have been true when Dr. E. F. “Ted” Codd was still alive.

Along with Eugene Wong and grad student Jerry Held, Mike founded and ran the INGRES research project at UC Berkely, which directly spun off the company later known as Ingres, Oracle’s chief direct competitor in its early years. One of his key lieutenants (and successors) was Bob Epstein, who designed Sybase‘s database technology, which is also the core of Microsoft‘s DBMS. Jerry Held went on to run much of development at Tandem, starting with Non-Stop SQL, the first industrial-strength relational DBMS, and later ran the database products for Oracle.

Mike himself went on with the POSTGRES project, which introduced an approach to user defined functions and abstract data types that swept the DBMS industry. POSTGRES begat Illustra, which was acquired by and became integral to the products of Informix, where Mike also served as CTO. Informix’s database technology was of course later taken over by IBM.

That’s quite a track record, although there are also a couple of more or less failed startups along the way. …

The IEEE awarded Mike its most recent John von Neumann medal, which seems to be a big deal. Here’s the citation.
