Data is at the core of your organization. Developing, accessing, and protecting your data should be a primary concern for every business owner and IT team. Choose wisely the tool you use to store your data.
Let’s see what it takes to convert Access database (.mdb file) into a SQL Server database (.mdf file)?
Understanding SQL is very much essential as every query in Microsoft Access uses SQL. Access supports the Transact-SQL variant of the SQL language used to construct queries or SQL statements. Access has storage limitations, whereas, SQL server can store vast amounts of data that can be queried quickly and efficiently.
Migrating Access to SQL server is no easy task as it is required to preserver the access data during SQL server conversion. Proper preparation is require like backing up the Access databases that you will be migrating along with the SQL server databases into which Access objects and data will be loaded. Not all Access features and settings are easily converted to SQL server due to code compatibility issues.
Access is a great starting database management system if you are using a desktop application or have only a few users, with fairly straightforward needs and your storage requirements are less than 2 GB. Access is fast and easy to develop on and is fairly inexpensive. These are some of the qualities that make Microsoft Access the world’s most popular desktop database engine.
However, once your data requirements become more sophisticated, you need to look at other options. Factors that drive the decision include:
- Moving to web based applications
- Multiple simultaneous users
- New functional requirements
- Increased data storage and retrieval needs
- Data security and maintenance
Microsoft SQL Server is scalable, reliable, and secure. It is the logical next step for Access database users and the most widely adopted conversion option.
SQL Server has the following advantages:
- Better performance and scalability.
- Interoperability with multiple applications.
- More secure than data in file server databases.
- Better database maintenance and integrity.
- Availability of skilled professionals.
The .NET Framework is fully integrated with SQL Server, the primary choice for critical data application needs that Access cannot match. Moreover, if your applications are running within the .NET Framework, they can communicate directly with the SQL Server database without an added ODBC layer
HOW TO MIGRATE
As applications become more complex there is a necessity to upsize it to Microsoft SQL Server database. Upsizing involves migrating database objects from Access database to SQL server database. Access data is loaded to SQL server using an Upsizing tool like the Upsizing Wizard, which comes along with the Microsoft SQL Server. Upsizing Wizard has limitations as it does not upsize table-level validation rules, mismatch in linking the tables to SQL server, problems in declaring referential integrity, and the like. Ensuring a clear Access codebase reduces the conversion errors.
Another SQL server migration tool from Microsoft is the SQL Server Access Migration Assistant(SSMA) for converting Microsoft Access to SQL server. What makes it different form the Upsizing Wizard is its ability to easily rerun migration. At the time of conversion, Access data will have to be loaded into the SQL server one table at a time in an incremental manner and queries run for each table converting it to SQL server database. Check the log to resolve queries and errors. Resulting SQL server system will be tested numerous times to make sure the system performs as expected.
There are numerous tools that facilitate converting MS-Access application to ASP.NET. ASP.NET being a server-side Web application framework is ideally designed to produce dynamic web pages for Web development. Various automation tools are available that facilitate the automatic generation of ASP.NET pages. There are tools powerful enough that can convert an Access or ODBC database to a full grown ASP application.
The overall process of migrating Access database to SQL server requires planning, RDBMS database design experience, and SQL coding and testing experience. At Macrosoft, we employ a team of highly skilled software engineers and analysts, strong in both Access and .NET / SQL Server. Our team has supported multiple conversions from Access to SQL Server, many of which have included migrating desktop applications to the .NET Framework. We are a Microsoft Gold Certified Partner so we have access to the very best in training, support and resources.
