Star schema: A data warehouse model, which consists of one fact (major) table and many dimension (minor) tables. The fact table stores the primary keys for all dimension tables. Statement: In programming, an expression or generalized instruction in a source language. Static RAM (SRAM): A type of RAM that does not need any special generator circuits to retain the stored data. It is faster, costlier, and consumes more power than dynamic RAM. Storage: See memory. Storage hierarchy: A hierarchy of storage technologies (such as cache memory, main memory, secondary storage and mass storage) used in a computer system. This is usually done because a single type of storage in not superior in speed of access, capacity, and cost. Stored program computer: A computer where the program to solve a problem and the necessary data are stored in its memory. StriNg Oriented symBOlic Language (SNOBOL): A programming language designed to manipulate strings of characters and used for non-numeric applications. Structured design: A system design approach in which a difficult problem is broken into smaller problems that is small enough to manage but independent enough to solve separately. Structured programming: An organized approach to programming involving the use of the three basic control structures - sequence, selection, and iteration, and the use of top-down concepts to decompose main functions into lower-level components for modular coding purposes. Study phase: A system life-cycle phase during which a problem is identified, alternative solutions are studied, and the most feasible solution is selected. Subprocedure: See subroutine. Subprogram: See subroutine. Subroutine: A standardized program written in such a way that it can be used as part of another program whenever necessary. A subroutine is normally invoked through other programs by the use of CALL statement...
