Two of the database systems of most popular Web are used by developers today are MySQL and MS SQL Server. Both are similar in terms of data storage and retrieval systems. The two systems support primary keys, along with key indices which can speed up queries and reduce the entry. In addition, both systems offer some support for XML.
Apart from prices, which is the obvious difference that distinguishes these two systems, and what is right for you?The two are about to products of primary data differences and explain the advantages and disadvantages for your business.
Open Source vs. Proprietary
When it comes to these two databases, the differences begin with the open source nature of MySQL against the closed structure, owned by the SQL Server. MySQL is an extensible, open storage, the database engine, and offers several variations, such as Berkeley DB, InnoDB and MyISAM Heap. Moreover, with theMicrosoft product, is in a Sybase-derived engine limited through good times and bad.
When considering how MySQL can be seamlessly integrated into a series of web programming languages and other technologies, it certainly has the advantage over MS SQL in the kind of compatibility, because the SQL Server is known to work better with other Microsoft products .
Licensing
Contrary to popular belief, is the system of MySQL is not always free. On the other hand, isincreasingly affordable. Therefore the licensing fees of products are presented in two levels of the system. With MS SQL to be the best way for a developer to receive a license, a license for the Microsoft Developer Suite or Microsoft Visual Studio to buy. Both offer a free license to use the SQL Server development. To use the product in a commercial environment, you must purchase a minimum of SQL Server Standard Edition - which could support more than $ 1000 for a couple of customersConnections.
Because MySQL is a system open source under the GNU General Public License, developers can use for free, provided that the projects also open source. However, if you intend to sell their software as a patented product, you need a business license, which costs about $ 400 for the purchase of up to nine clients. Depending on the project and money is MySQL the advantage of being here.
Technical differences
Open source vsowned fighting is only one of the most common causes of why some users choose a system over another. However, there are some differences from a technical aspect as well.
For example, MySQL does not offer full support for foreign keys, ie, not all relational properties of MS-SQL, the relational database as a whole. Some versions of MySQL also lacks support for stored procedures - the biggest drawback is the system that does not support MyISAMTrans.
Performance
In performance mode, MySQL is the clear leader, especially in the format of the default MyISAM table. MyISAM databases you can create a small space, with very little storage space, memory and CPU. While the system runs on the Windows platform without errors, which tends to be better on Linux and other UNIX systems. Because of its stability, many large companies like Yahoo! Using MySQL as the database end.
When it comes toPerformance, with the power of MS SQL is packed with more features than other systems, perhaps its greatest disadvantage. Although most of these features are designed to optimize performance, tend to sacrifice other essentials. The cost here is the complexity and hardware resources on the road and memory, leading to worse outcomes. If you lack the knowledge and enough hardware to run would be a SQL server support, better management system of different databasesSystem.
Security
These two sets of databases are strongly rooted in security terms. Both have adequate safety mechanisms by default, but you follow the instructions and software security patches to keep up to date. Both work in intellectual property known ports, which unfortunately draws a crowd of invaders, a disadvantage that can be attributed both to products. The good news is that MySQL and MS SQL to change the ports, permitted only if the rule is thatvulnerable.
Recovery
As for the recovery comes, the SQL Server has a definite advantage over MySQL, which tends to fall a bit short on its MyISAM configuration. A UPS system is required for MyISAM, accounting for continued operation. If a power failure should occur, can the corruption and loss of important data. With the corruption of the SQL Server data are unlikely. The data travels through several checkpoints at the intersection on your keyboard to the hardDisk and monitor. In addition, SQL Server keeps track of the process, even if the system shuts down unexpectedly.
The best option
As you can see, both systems have their advantages and disadvantages. In our view, a product that allows it to be efficient is a good database, there is something else that is not worth your time and frustration. When it comes to MySQL and MS SQL, the decision comes down to the situation and all thatThey are looking to achieve.
