A database management system (DBMS) solves most of the problem with using flat files. What of the following are problems with using flat files.

		Handling multiple file write at the same time.
		Race conditions even with locks.
		When a file grows large, working with it can be very slow.
		Searching for a particular record or group of records in a flat file is difficult.
		Dealing with concurrent access can become problematic: bottleneck problem.
		Inserting records into or deleting records from the middle of the file (random access) can be difficult.
		Beyond the limits offered by file permissions, there is no easy way of enforcing different levels of access to data.
