Migrating merged Access databases to SQL Server

This article explores the benefits of access and the SQL Server consolidation process and provides links to more in-depth analysis and migration processes ...

Microsoft access is a simple, easy-to-use development tool that can write access programs even if you don't have development experience. There may be internal access databases in many departments within your organization that have been created for some reason and have been around for a long time. On the other hand, there are also important reasons to merge the Access databases in these departments into a centralized SQL Server database.

Reasons to migrate an Access database to SQL Server

Here are some of the main reasons to migrate an external Access database to a SQL Server environment:

Multiple user access to the database. Access databases may now be popular in your user base, but this can also cause problems. Access databases can only meet the needs of a small number of users at the appropriate performance level. If more users start using this application, the Access database cannot be extended well. SQL Server, which can handle thousands of users, is the ideal choice for a multiuser environment.

Redesign and write to make the application a little bit more performance better. It may now be the right time to rewrite existing applications, so that the application is less and better. Many access applications are probably developed by people from unprofessional IT departments, and access is not very familiar to them. The code and database may not be developed according to existing development standards, and the quality of the design and writing may be poor due to the lack of sufficient experience and time. By centralizing common processing, your entire organization can benefit from standardizing and unifying applications and data.

Exchange data with the external environment. SQL Server provides better tools to communicate with other environments such as Oracle, DB2, and SAP. Data interchange with other environments can be automatically processed or integrated in existing applications through Data transformation Service/Integration Services (Transformation Services/integration Services, dts/ssis).

More advanced methods of analyzing and solving performance problems. These tools include the execution plan in SQL Profiler,query Analyzer (execution plans), the Index Tuning Wizard, and the use of filegroup to extend data across disks. SQL Server also has a better locking mechanism designed for multi-user environments.
