Techopedia Explains Microsoft Access
The Access Jet engine supports most database features, such as referential integrity, row-level locking and multiuser support with up to 255 concurrent user connections. Access is well-suited for creating small databases such as those used by single departments. It is not suitable for larger, enterprise-level databases. For these, Microsoft offers its SQL Server database engine.
