as many as you want
An Access database can hold up to 2GB (two gigabytes) of information. These include up to 32,768 objects ( tables, queries, forms, etc). From this up to 255 people can use the database at the same time. My source: MS Access 2010 Comprehensive, New Perspectives, Adamski::Finegan rosie stjulian

You can have as many windows as you want open at one time.
Access is a great database application that can be used for both single and multiple uses of a one time operating business.
Data sharing in a database refers to the ability to allow multiple users or applications to access the same data in a controlled and secure manner. It ensures that data is shared efficiently without conflicts or inconsistencies, enabling collaboration and real-time updates among users. Proper access controls and permissions are essential to protect the integrity and confidentiality of the shared data.
Concurrent access in databases means two or more sessions accessing the database at the same time. Note that a session does not necessarily mean a user is physically infront of a terminal, it could also mean two or more processes accessing the database.
Reduced data redundancy, Improved data integrity, Shared data, Easier access, Reduced development time
the difference is about the transactions. the normal database is not included deadline, but the real time database is.
The relationships between database applications DBMS and databases is as follows: Databases can be simple or complex. simple databases can be kept in a Microsoft Excel spreadsheet or they can be maintained in a user generated Microsoft Access database which can be programmed to query certain data that has been entered into that database over a period of time. Microsoft Excel and Microsoft Access are also applications that are used to build databases that can be incorporated into DBMS or Database Management Systems. These systems can be extremely complex or they can be simple meaning that maintenance to these systems is not demanding. If the DBMS is complex it may require an entire team of technicians and in some cases engineers.The relationship between users, database applications, databases, and Database Management Systems can be simplified even further - Users can access a database that has been created with a database application to query managed data that is a part of a uniform Database management system.

Largest database More strong analytical tools able for generating output (textually, graphically and also animations) Increased adoption of MySQL Improving replication technologies Web 2.0 Mirroring and replication will enable offline data access Mobile data access
It depends what you mean by 'cant access'. a) If your computer crashed while a file was open - Open Office should automatically attempt to recover the file next time you open it. b) If the file is locked by a password - you need to enter the correct password to open it.
