- relational algebra — (database, theory) A family of algebra with a well-founded semantics used for modelling the data stored in relational databases, and defining queries on it. The main operations of the relational algebra are the set operations (such as union, intersection, and cartesian product), selection (keeping only some lines of a table) and the projection (keeping only some columns).

- rotational latency — (storage, hardware) The time for the start of the required sector on a disk to appear underneath the read/write head. The worst case is where it has just passed the head when the request is received. For a disk drive with N heads per surface, rotating at R revolutions per minute, the average rotational latency will be L = 30/NR seconds. Rotational latency is one component of access time.

- xml template pages — (web) (XTP) JSP transformed by XSL stylesheets. An XTP page is basically a JSP page which specifies an XSL stylesheet.

JSP programmers can use XTP used as an easy introduction to XSL, incrementally applying styles to their pages.
