Discuss how you would want a query optimiser within an ORDBMS to handle this type of query. Use a relational algebra tree to illustrate your answer.
Consider the following schema: Pet (petNo, petName, petDescription, dateRegistered, picture, surgeryNo, doctorStaffNo) Staff (staffNo, sName, sAddress, position, surgeryNo) Surgery (surgeryNo, surgeryAddress, surgeryTelNo) where: Pet contains details of pets and the pet number (petNo) is the key. The surgery where the pet is registered is given by the surgery number (surgeryNo). A pet can only be registered with one surgery at a time. The doctor who treats the pet is given by the doctorStaffNo. Picture contains an image of the pet. Staff contains details of staff and staff number (staffNo) is the key. Surgery contains details of each surgery and the surgery number (surgeryNo) is the key. Now consider the following SQL:2003 query: SELECT petNo, staffNo FROM Pet p, TABLE StaffDoctors s WHERE p.doctorStaffNo = s.staffNo AND p.brownShortHairedTerrier(picture) AND s.surgeryNo = ‘S3’ AND p.dateRegistered < ‘1-Jan-90’; The routine brownShortHairedTerrier() is an externally defined routine that searches the specified image for certain characteristics. The StaffDoctors() function is fully defined within SQL3 as: CREATE FUNCTION StaffDoctors() RETURNS SET(Staff) SELECT * FROM Staff WHERE position = ‘Doctor’;
Which logical function evaluates two or more arguments and returns TRUE if any one of the arguments is true, and FALSE only if all of the statements are false?
A) AND B) NOR C) OR D) NOT
