Avoiding Indirect References in DB2 11

When designing the physical structure “table space” used to store table data, DBAs must understand the types of processing that will occur against the table. Will the table have lots of inserts, updates or deletes, or is it mainly read-only? Will the table rows be variable length due to either VARCHAR columns or data compression? Answering these questions helps DBAs choose the appropriate table space storage options during the creation.

IT Service—Service Oriented Architecture

In this post, I discuss service oriented architecture (SOA). It is a brilliant IT notion. Brilliant, really? Yes, let me explain.

SOA is amazing. It is beautiful in its simplicity and usefulness. The idea is to create a software entity that has self-describing inputs and useful outputs that can be accessed either publically or privately, as appropriate, in such a way that the underlying complexity of the root systems and software is shielded from the invoker of the service. With this approach, all kinds of existing data and programmatic functionality can be easily accessed from environments that would otherwise be foreign to the native environment of the data or program.
