• The process of cleaning data to make it consistent in preparation for data warehouse retrieval.

search item

• Primary key - SI
• A field within a table that is used for calculated access in parent tables, and chained access in child tables

select item

• An item in a SQL SELECT statement's select-list. See the SQL Reference for details on valid select-list items.

select-list

• A comma separated list of items to be returned to the application in a SQL SELECT statement. See the SQL Reference for details on valid select-list items.

sequential read

• A search of a file or database performed by comparing successive records with search criteria.

• The part of the client/server architecture which refers to the host CPU where the database and other corporate information is stored.

SI domain

• An affiliation of one parent table, and one or more child tables, linked at installation, whose keyword values are all indexed in the same indexes. See also: search item.

snowflake schema

• A type of database design used in data warehousing involving multiple tables in a hierarchy within a given dimension i.e., data is organized into parent tables with branches to child tables and so-called grandparent tables (snow flakes).
• When the schema is displayed graphically, it has the appearance of a snow flake.

soundex

• ;SX
• an indexing option which allows data retrieval based on phonetic arguments, useful for location of data with keys that are difficult to spell or that can be spelled in several ways.

star schema

• A type of database design used in data warehousing composed of a large sized fact table combined with numerous dimension tables, i.e., parent tables branched to child tables.

summary table

• A table containing pre-summarized data, typically used in ROLAP data warehousing, used to perform fast look-ups against specific, predictable combinations of criteria.
• Omnidex aggregation indexes eliminate the need for summary tables.

superview
