Three main types of database applications and briefly explain them with suitable example?
A collection of programs that enables you to store, modify, and extract information from a database. There are many different types of DBMSs, ranging from small systems that run on personal computers to huge systems that run on mainframes. The following are examples of database applications:computerized library systemsautomated teller machinesflight reservation systemscomputerized parts inventory systemsFrom a technical standpoint, DBMSs can differ widely. The terms relational, network, flat, and hierarchical all refer to the way a DBMS organizes information internally. The internal organization can affect how quickly and flexibly you can extract information.
What is a Lock in DBMS?
One major problem in databases is concurrency. Concurrency problems arise when multiple processes try to update or insert data into a database table at the same time. Such concurrent updates can cause data to become corrupt.Locking is a strategy that is used to prevent such concurrent updates to data.When a database system modifies data in one of its tables it first acquires a lock. When a table is locked, only the process the acquired the lock is allowed to modify the data in the table. Other processes will have to wait until the lock is released before they can make their changes. Now, this is a simple representation of how locking works. In reality databases can use different locking strategies.Depending on the database system, locks can be acquired on entire tables (table-level locking) or on individual rows (row-level locking).

What does a Hierarchical database do?
