Relational Database Design 1 10 Relational Database Design Anomalies can be removed from relation designs by decomposing them until they are in a normal form. Several problems should be investigated regarding a decomposition. A decomposition of a relation scheme, R, is a set of relation schemes {R1, . . . ,Rn} 𝑅 = 𝑖𝑅 𝑛ڂ […]

SQL 1 SQL-99 SQL = Structured Query Language (pronounced “sequel”). An ANSI/ISO standard language for querying and manipulating relational DBMSs. Developed at IBM (San Jose Lab) during the 1970’s, and standardised during the 1980’s. Appears that SQL will survive the rise of object-relational database systems. Designed to be a “human readable” language supporting: ◦ relational
