Abstract :
IXSQL, an extension to SQL, is proposed for the management of interval data. IXSQL is syntactically and semantically upwards consistent with SQL2. Its specification has been based both on theoretical results and actual user requirements for the management of temporal data, a special case of interval data. Design decisions and implementation issues are also discussed
