After learning about the advantages of the open-source RDBMS Relational Database Management System, you have installed the MySQL database to provide registration, subscription, and e-commerce services for Web applications. Database reliability alone is far from enough to meet your business needs. It is best to have access to the source code and the product is free of charge.

Now you begin to assess future growth and project business needs and hesitate to migrate data to a more reliable business software system, such as SQL Server or Oracle.

However, product software products are not free of charge, unless you use the Express free version, many software vendors can now provide this free version. For example, you can download SQL Server Express, Oracle Database XE, or DB2 Express-C, which can be used for free. They are not open-source, but you don't have to pay. The free version of commercial products is not as robust as the paid version, and there are not so many features, but they have functions not available in open-source software. At the same time, free commercial products cannot compete with their open-source software products in some respects. Before considering the conversion, there are several important issues to consider.

What environment do you want to consider using? It is often the current database environment that determines what changes you can make to the system. For example, SQL Server can only run in Windows, but you may use Linux. However, if you want to integrate database security with Windows security, and MySQL does not support Windows models, converting to SQL Server is your best solution.

There are many such factors to consider. Free commercial software products have limits on memory, database size, and CPU usage. For example, Oracle Database XE and SQL Server Express both have 4G Database size restrictions. There are also restrictions on other factors, such as whether to support certain application interfaces, scalability requirements or availability requirements.

What functions should your RDBMS have? When deciding whether to abandon the transition from an open source RDBMS to commercial software, you must first familiarize yourself with the functions of different database systems. Most RDBMS kernels are similar, whether open-source products or free commercial software versions. They all comply with the ansi SQL standard of the American National Standards Institute, support ACID transactions (atomicity, consistency, independence and durability), provide security, including stored procedures and triggers, support for replication and partitioning, provides indexes and many other functions.

In fact, not all products are the same. For example, many functions of SQL Server Express are not available in MySQL. SQL Server provides Management Studio, Configuration Manager, Report Server, online backup, automatic optimization, and other functions. MySQL supports different storage engines and provides partition options for easier installation. When MySQL is selected, it is important that it can run on any operating system and is open-source, and the size of the database is limited only by the size of the host operating system file. Find out which product supports which features and decide which of these functions are required. This is the key.

What does the implementation need to do? This may be the most important issue in deciding whether to migrate to commercial software. Free commercial products provide functions not available in open-source software, which is a smooth migration path to more robust commercial software versions. For example, your organization may want to implement expanded business intelligence analysis next year. To this end, you want to have a system that can process the necessary data extraction, conversion, and loading (ETL) operations and support the increasing data warehouses, provides online analysis and extended report analysis functions.

Undoubtedly, you can integrate many of these features with different open-source software products. ETL products such as Pentaho Data Integration and Talend Open Studio are powerful Open-source tools that can be used to migrate Data. However, products such as SQL Server include not only database engines, but also their own analysis services, report services, and integration services to provide scalable solutions, seamless long-term planning and subsequent implementation. Therefore, SQL Server Express may be a good choice.

Where does it start? There is no simple answer to the migration of Open Source RDBMS. Every system has its own advantages and disadvantages. Free commercial software is not necessarily cheap. You must take into account the time required to plan and implement different components, understand and discover the support for these components, and integrate different strategies and systems. In some cases, the solution may be clear. If you have bought Microsoft products and are using Microsoft tools to run. net applications, SQL Server may be the best solution. However, if you are running a Linux server and support PHP applications, you may find that open-source software such as PostgreSQL can better meet your current needs. However, it is not that easy. You must consider the limits and functions of the product and future requirements. Only in this way can you make the right decisions.
