Final answer:
Locking a table in either SHARE MODE or EXCLUSIVE MODE is determined by the capabilities and design of the database management system, not by specific databases, data type, or the size of the table.
Step-by-step explanation:
A table can be locked in SHARE MODE or EXCLUSIVE MODE depending on the database management system (DBMS). Locking a table in SHARE MODE allows multiple transactions to read from the table at the same time, but no transactions are allowed to write to the table until it is unlocked. On the other hand, locking a table in EXCLUSIVE MODE means that a single transaction has both read and write access to the table, and no other transactions can read or write to the table until the lock is released. These locking mechanisms are used to maintain database integrity and are not necessarily dependent on factors such as specific databases, data type, or the size of the table but rather on the capabilities and design of the DBMS.
