Overview

DBIX was a commercial client/server SQL database sold by Halcyon Software in the mid-1990s as a low-cost alternative to the big RDBMS vendors. It ran on Windows 3.x, NT and 95 as well as SunOS, Solaris (SPARC and x86), AIX, HP-UX, Digital UNIX, SCO and Linux, and offered transaction logging, crash recovery, record-level locking, ANSI SQL and an ODBC interface, with extra cursor-sharing extensions on Windows. It was positioned as the back end for Halcyon's VBIX tools, which ported Visual Basic-style applications to Unix. The product disappeared around the end of the decade and the vbix.com domain is now parked, so it is of historical interest only.

Strengths & trade-offs

Strengths

  • +Unusually broad 1990s platform list: Windows plus most commercial Unixes and early Linux
  • +Transaction log, crash recovery and record-level locking at a budget price point
  • +Standard ODBC interface rather than a proprietary API

Trade-offs

  • −Discontinued for over two decades; no binaries, documentation or support remain
  • −Never built a third-party tool or community ecosystem

Great for

  • +Historical reference on low-cost 1990s SQL servers
  • +Identifying legacy systems that still reference DBIX data files

Think twice for

  • −Any new or production workload

DBIX FAQ

What is DBIX?

DBIX is a relational database by Halcyon Software, Inc., first released in 1996. DBIX was a commercial client/server SQL database sold by Halcyon Software in the mid-1990s as a low-cost alternative to the big RDBMS vendors. It ran on Windows 3.x, NT and 95 as well as SunOS, Solaris (SPARC and x86), AIX, HP-UX, Digital UNIX, SCO and Linux, and offered transaction logging, crash recovery, record-level locking, ANSI SQL and an ODBC interface, with extra cursor-sharing extensions on Windows. It was positioned as the back end for Halcyon's VBIX tools, which ported Visual Basic-style applications to Unix. The product disappeared around the end of the decade and the vbix.com domain is now parked, so it is of historical interest only.

Is DBIX open source?

No. DBIX is proprietary, closed-source software.

Does DBIX support ACID transactions?

Yes. DBIX supports full ACID transactions, with strong consistency.

Does DBIX scale horizontally?

DBIX does not scale horizontally; it runs on a single node, so you scale it up rather than out. It is comfortable at small scale (≤ 100 GB).

How can I run DBIX?

You can self-host it.

What is DBIX best for?

DBIX is a strong fit for historical reference on low-cost 1990s SQL servers and identifying legacy systems that still reference DBIX data files. Think twice for any new or production workload.

What are the best alternatives to DBIX?

Common alternatives to DBIX include PostgreSQL, MySQL, Firebird, SQLite and Progress OpenEdge. The right choice depends on your workload, scale and hosting; WhichDB's smart match ranks them against your requirements.

Is DBIX still maintained?

DBIX is discontinued. Sold by Halcyon Software c. 1996-1999; no releases or vendor site since, and vbix.com is now a parked domain.

How popular is DBIX?

DBIX has little measurable public adoption today, so it ranks near the bottom of the WhichDB Score.
