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 Design Decomposition Blog is written by Doug Barry.
An application server is a component-based product that resides in the
middle-tier of a server centric architecture. It
provides middleware services for security and state maintenance, along with data
access and persistence.
Java application servers are based on the Java™ 2 Platform, Enterprise
Edition (J2EE™). J2EE uses a multi-tier distributed model. This model
generally includes a Client Tier, a Middle Tier, and an EIS Tier. The Client Tier can
be one or more applications or browsers. The J2EE Platform is in the Middle Tier
and consists of a Web Server and an EJB Server. (These servers are also called
"containers.") There can be additional sub-tiers in the middle tier.
The Enterprise Information System (EIS) tier has the existing applications,
files, and databases.
For the storage of business data, the J2EE platform requires a database that
is accessible through the JDBC, SQLJ, or JDO API. The database may be accessible from web components, enterprise beans, and application client components. The database need not be
accessible from applets.
