| Relational databases work by storing data in [[w:Table (database)|tabular form]] where [[w:column (database)|columns]] represent data items of predetermined type and [[w:row (database)|rows]] represent the values each "item" has. Relational databases are accessed mainly with [[w:SQL|SQL]] ( Structured Query Language ). However the RDBMS converts that into [[w:relational algebra|relational algebra]] and optimizes that and the relational algebra query actually returns the result table that has those columns and rows you requested. | | Relational databases work by translating [[w:SQL|SQL]] into [[w:relational algebra|relational algebra]] and optimizing and the relational algebra query actually returns the rows. |
