You may have heard that "ODBMSs don't handle queries." I often hear this at conferences and from clients. I'm here to tell you that this just ain't so.
The facts are quite different. Most ODBMSs support queries, but they sometimes support queries in different ways. The table below provides information on the query capabilities of ODBMSs. Note that the market leading ODBMSs all support queries -- they all have since the early 1990s. This table is from the final release of the Object Storage Fact Book that was published in July, 2001. Some of the product names have changed since that date.

One possible reason for this myth is the widespread publicity that Dr. Michael Stonebraker's DBMS Matrix received over the years. See Stonebraker's DBMS Matrix.
