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—Managed Services

In this post, I discuss managed services, which like IT service management is an instance of the diverse elements known as an IT service.

Managed services are usually associated with getting someone else to handle day-to-day management responsibilities and functions like application testing, systems and network management, or data center hosting. These are just representative examples and there are many other instances of managed services in the marketplace. The “someone else” is an IT services company that leverages labor and perhaps hardware and software to perform a collection of IT services.
