Lock granularity specifies which resource is. understanding locks in dbms: If one application holds a lock on a database object, another application might not be able to access. It requires that a transaction t i that attempts to lock a node must follow these protocols: Three types of lock granularity are course granularity,. granularity is the size of data items that are allowed to lock. At its basic, a database lock exists to prevent two or more database users from performing any change on the same data item at the very same time. A programmer working in a multiprocessor environment must decide how many separate locks. in computer science, multiple granularity locking ( mgl) is a locking method used in database management systems (dbms). the granularity of locks in a database refers to how much of the data is locked at one time. multiple granularity locking can be implemented in dbms by defining different levels of granularity for the. lock granularity refers to the size or scope of the resource that a lock protects. one approach to concurrency control is multiple granularity locking, which allows different levels of granularity for.
