You might have seen the recent news reports about the collision between U.S. and Russian communication satellites. The U.S. satellite was one of the Iridium satellites. What wasn’t reported and you probably don’t know is that an object database management system (ODBMS) is an important part of the Iridium system. Even though ODBMSs are a [...]

The typical definition of an atomic task or process is one that cannot be decomposed further. This is vague and subject to interpretation.

The primary error in Stonebraker's DBMS Matrix is the apparent
assumption that ODBMSs do not have a query capability. That is false as can be
seen in the table (new window) on the page that introduced
this myth.
So, let us revisit the DBMS Matrix. Redrawing it with the facts on ODBMS
queries, the DBMS Matrix now looks like the following figure.
This is, however, not very useful for classifying DBMSs. Its basic
message is that you can handle complex data with either an Object-Relational
DBMS or an Object DBMS.
What about performance on complex data? That can be used to create a better
DBMS Matrix. Before creating the better matrix, see the navigating
objects page.
