For more information, see Migrate an Access database to SQL Server.Īdditional reasons for separating data and logic include the following:ĭata integrity and security If you combine data and logic in one file, the data is exposed to the same risks as the application logic. For more information, see Split an Access database.Īnother way to separate data management and application logic is by using a database server program (such as Microsoft SQL Server) for data management, and Access for application logic. You can even distribute different front-end files to different users. You distribute the front-end file, one copy for each user, to their computers. You put the back-end database in a shared location, such as a network folder. For example, a database called MySolution.accdb is split into two files called MySolution_fe.accdb and MySolution_be.accdb. This command splits your database application into two Access files: one for logic (a front-end) and one for data (a back-end). One way to separate data and logic is by using the Access Database command (on the Database Tools tab, in the Move Data group). This helps improve performance and reliability. In most cases, you should separate data management and application logic. For example, a user could cause data loss by unintentionally deleting or damaging the application file. Combining data management and application logic in one file provides the simplest deployment method, but this method works best only if a few people use the application at the same time, and it involves some risk. This is the default application structure in Access. You can create an Access application that combines data management and application logic in one file. Should the data and the logic be separated?
Understand and download the Access RuntimeĪCE no longer requires a separate installation to interact with non-Office appsīefore you begin, you should ask yourself the following questions about the way that the application will be deployed. This article discusses basic deployment planning, packaging and signing, deploying database applications, and the Access Runtime environment. A database application is a computer program that provides both a way to store and manage data and a user interface that follows the logic of business tasks (application logic). LessĪccess provides a feature-rich platform for developing database applications.

I keep looking at other errors for this type and it says it's a comma, period or parenthesis missing but I can't see where that would fit in the code below. The code is attached to an event when click on Enter of the text field Last_Date_of_Passed_Inspection I am getting an Microsoft run time error '2465' Microsoft cannot find the field txtlast_date_of_passed_inspection reflected in the expression when I run the following code below.
