2 gigabytes, minus the space needed for system objects. Note: You can work around this size limitation by linking to tables in other Access databases . You can link to tables in multiple database files, each of which can be as large as 2GB.
This is what I learned. it’s a max of 2 Gb that Access can hold in one database. There’s no limit on the number of records. So 6 Mb records allow for a recordsize of approx 333 characters.
This of course begs the question “How can I build a database larger than 2GB in access?”
Therefore in order to build Access databases larger than 2 Gbytes, you have to put the database tables in separate files, and then create links to those tables from a primary database file. Retired programmer & systems architect.
Although a single file can only hold 2GB, you can set up access with databases with much more than 2GB. For example you could have one database file with all the forms and reports, linking to multiple other files with the data in.
How many users can Microsoft Access handle?
A discussion to confront the myth that Microsoft Access applications can handle no more than 20 or 30 users. We believe it can handle hundreds of simultaneous users with a Microsoft Access back end database, and a virtually unlimited number if linked to a SQL Server database: I agree with you that Access can handle hundreds of simultaneous users.
We of course, what matters is the number of simultaneous users, and what they’re doing. If everyone is just viewing data or entering data into a table, that takes very little work and a large number of people (well over 200 ) can be supported. People cannot type faster than what Access can handle.
For full details of various limitations in MS Access, refer to this web page: Microsoft Access Specifications and Limitations. The maximum size of an MS Access database file is 2GB (if your file gets larger than that, some very strange things start to happen).
Number of fields in a table 255 Number of open tables 2048. The actual number will be fewer because of tables opened internally by Microsoft Access. Table size 2 GB minus the space needed for the system objects. Number of characters in a Text field.
How many users can access an access database at once?
If you mean how many users can access an Access database simultaneously, the theoretical limit is 255 but in practice it’s between two and about six before performance, reliability, and sometimes database integrity suffer to the point of failure. MS Access makes a good front-end for SQL DBMSs like Postgre, sql, my SQL, and Microsoft SQL Server.
This begs the question “How many simultaneous users can a database handle?”
One answer is that we believe it can handle hundreds of simultaneous users with a Microsoft Access back end database, and a virtually unlimited number if linked to a SQL Server database: I agree with you that Access can handle hundreds of simultaneous users.
