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 Decomposition Matrix on this site uses a specific definition: A task (for business process diagrams) or a process (for data flow diagrams) is atomic if every input relates to every output [...]

The Design Decomposition Blog is written by Doug Barry.
This figure presents a comparison of some basic terms used in relational and
object technology. New technology, in this case object technology, often creates
new terms to go with the new technology. There are similarities and differences
between relational and object technology. For example, a relation is similar to
a class. Yet, a relation does not have the concept of inheritance that is found
with a class. A tuple is similar to an instance object. Yet, a tuple is limited
to the data structure it can hold. An instance object can handle any data
structure supported by C++ or Java. A column is similar to an attribute. Yet, a
column is limited to certain data types. An attribute can hold any C++ or Java
data type including references to other objects. Finally, a stored procedure is
significantly different than a method. Methods are computationally complete
because they are written in object programming languages such as C++ or Java.
Most stored procedure languages are limited when compared to C++ or Java.
