Boyce and Chamberlin invented an English-like language for these entities.
Heath's theorem can be used to decompose certain components of these entities if those components satisfy a functional dependency. These entities can be used for OLAP if they are designed with a star schema. Edgar F.Â Codd proposed a model for these entities, and with Raymond F.Â Boyce, he is the namesake of a normal form of these entities. Boyce and Chamberlin invented an English-like language for these entities. Jim Grey identified (*) atomicity, consistency, isolation, and durability, or ACID, as four important properties of transactions in these entities. In a language used to manipulate these entities, one can use the JOIN clause to combine rows from two or more tables. In that same language, one can use a SELECT statement to query the "relational" type of these entities. For 10 points, SQL is used to manipulate what computerized collections of information?
