Microsoft Access Database Scalability: How many users can it support?

Posted on by

What’s the Maximum Number of Microsoft Access Users?

Microsoft Access 2013There is a persistent myth that Microsoft Access Jet databases can only support 20 or so users. Here’s my response to a recent inquiry:

I flatly refute any suggestions that Microsoft Access users are limited to around 30. We’ve run many tests and have never seen that kind of degradation in performance. It is a myth from Access 2.0 days that was eliminated with Access 97 almost two decades ago.

A poorly designed Access database won’t support two users, but a well designed Access solution can support hundreds of users. Of course, what matters is the number of simultaneous users, and what they’re doing.

At Least 200 Simultaneous Microsoft Access Users on an Access/Jet Database

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. If users are all running massive reports and queries with data updates, that can still be done but performance would be an issue which applies to any technology, so testing and optimization would be necessary.

Migrate Back-End Access Database to Microsoft SQL Server for More Users

Microsoft SQL ServerIf the back-end database is in SQL Server rather than an Access/Jet database, the number of users can be practically unlimited if each user has their own front-end copy of the Access application. Performance issues still apply based on what they are doing. In some cases SQL Server is slower than Access, so it is important to understand the situation before thinking SQL Server is the answer.

All that said, any Access application that is distributed to others with shared data should be a split database design. Here are a few resources we’ve written:

Total Access StartupSimplify Support for All the Users of Your Access Databases

Total Access Startup helps with the distribution of databases to each user’s desktop, and launching it with the right version of Microsoft Access.

This allows you to centrally support a large number of Access users across your network and ensure everyone is using the latest version of your application. It also simplifies the migration from one version of Access to another.

Using Terminal Services and RemoteApp to Extend Your Microsoft Access and other Windows Applications Over the Internet

Posted on by

Terminal Services RemoteApp and Microsoft AccessRead our new paper on using Terminal Services and RemoteApp to Extend Microsoft Access and Other Windows Applications Over the Internet.

One of the features of Microsoft Windows Server that is increasingly popular over the last few years is the Terminal Server and more recently RemoteApp. With few exceptions, most Windows applications work within a Terminal Server environment. By doing so, your investment in existing applications, and the power of Windows desktop features and interoperability, can be exposed over the Internet.

This is particularly powerful for database applications such as Microsoft Access since it eliminates the need to send large amounts of data over the Internet for Access to process and users do not need to install Access on their machine. With RemoteApp, you can set up a terminal server experience where your users can only run your application without running other applications or browsing your network. Easily web enable all your desktop applications.

Microsoft Windows 7 Service Pack 1 Breaks Backward Compatibility with ActiveX Data Objects (ADO)

Posted on by

The recent release of Windows 7, Service Pack 1 (and Windows 2008 R2) breaks backward compatibility for Microsoft ActiveX Data Objects (ADO). That means if your .NET, Visual Basic 6, VBA/Office, C++ or other program includes an ADO library reference, and you compile your application or COM object on a Windows 7 SP1 machine, it will not run when deployed to an earlier environment containing the existing ADO object.

An error you may encounter is: Unable to cast COM object of type ‘System.__ComObject’ to interface type ‘ADODB.Connection’.

Basically, the interface IDs for files like MSADO28.tlb and MSADO15.dll have changed. For more information on this, read the Microsoft KnowledgeBase article 2517589.

This is not an issue in Visual Studio .NET if you are using ADO.NET. But if you are using ADO, it is an issue. For .NET specific issues, see KnowledgeBase article 840667, You receive unexpected errors when using ADO and ADO Multidimensional in a .NET Framework application.

Note that applications built on the original version will run fine on Windows 7, SP1. You just can’t go backwards. Watch out!

Microsoft Access Database Compact and Repair to Minimize Corruption and Avoid Bloat (by Access Version)

Posted on by

File server databases like Access/JET MDB and ACCDB files need to be periodically compacted and repaired for optimal performance and to minimize database corruption. This also eliminates database bloat that can occur as data is added and deleted in the database.

Microsoft Access databases can be manually compacted from the Access menu. Unfortunately, over the last few versions of Access, the location of this command has moved around driving Access many users and developers crazy. Read our paper on Microsoft Access Database Compact and Repair to Minimize Corruption and Avoid Bloat (by Access Version).
