A directory service defines a namespace for the network. The namespace is used to assign a name (unique identifier) to each of the objects. Directories typically have a set of rules determining how network resources are named and identified, which usually includes a requirement that the identifiers be unique and unambiguous.
The Houston Oilers moved to Tennessee and became the Tennessee Oilers for the 1997 season. The team changed their name from Oilers to Titans in 1999. 1 person found this useful.
The new Titans franchise retained the Oilers' team history and records, while the team name was officially retired by then NFL Commissioner Paul Tagliabue, thus preventing a future Houston NFL team from using the name. The NFL would return to Houston in 2002 with a new franchise, the Houston Texans.
