Two of the most used database systems by web developers today are MySQL and Microsoft MS SQL server. Both are similar as regards to be the storage and retrieval systems. The two systems support primary keys, along with the major indexes that speed up queries and constrain input. In addition, both systems offer some form of support for XML.
Apart from the price, which is the obvious difference, what distinguishes these two systems, and which one is right for you? We overview both products, we point out the main differences and explain the advantages and disadvantages of using them for your business.
Open-source vs. Owner
When it comes to these two databases, the differences begin with the open source nature of MySQL vs. closed, the ownership structure of SQL Server. MySQL is an extensible, open storage engine database, offering multiple variants such as Berkeley DB, InnoDB, MyISAM and Heap. On the other hand, with the Microsoft product, you are limited to a Sybase shunt motor through both good times and bad.
When considering how MySQL works seamlessly with a variety of programming languages and other web-based technologies, certainly has the advantage over MS SQL in terms of compatibility, such as SQL Server is known to work better with other Microsoft products.
license
Contrary to popular belief, the MySQL system is not always free. On the other hand, it is always cheaper. With regard to both products, licensing costs is based on a two-level scheme. With MS SQL, the best way to get a developer license is to buy a license for the Microsoft Developer or Microsoft Visual Studio suite. Both provide you with a license SQL Server for free for development use. If you want to use the product in a commercial environment, you must purchase at least SQL Server Standard Edition - which could set you back more than $ 1,000 for a couple of client connections.
Because MySQL is an open-source system under the GNU General Public License, developers can use at no cost until the associated projects are also open-source. However, if you plan to sell software as a proprietary product, you would need to purchase a commercial license, which costs about $ 400 for up to nine guests. Depending on the project and the funds, MySQL can have the advantage here.
Technical differences
The open-source vs. proprietary battle alone is a major reason why some people choose one over the other system. However, there are some differences from the technical point of view.
For example, MySQL does not offer full support for foreign keys, which means it does not have all the relational features of MS SQL, which is considered a complete relational database. Some versions of MySQL also lacks full support for stored procedures - the biggest disadvantage of being the MyISAM system, which does not support transactions.
Performance
In the performance, MySQL is the undisputed leader, mainly because of the size of its default table MyISAM. MyISAM database to leave a small footprint using little disk space, memory and CPU. While the system runs on Windows platform, without blemish, we tend to perform better on Linux and other UNIX-like systems. Because of its stability, many power plants Internet like Yahoo! using MySQL as the back end database.
When it comes to performance, the strength of MS SQL to be packed with more features than other systems is perhaps its greatest disadvantage. Although most of these features are designed to optimize the performance, they tend to sacrifice other essential elements. Here is the cost and complexity of the hogging resources in the storage mode and memory, which leads to poorer performance. If you lack the knowledge and enough hardware to support a SQL server, it would be better off with another database management system.
Security
These two database systems are more or less stalled with regard to safety. Both are equipped with appropriate safety mechanisms by default, bearing follow the instructions and keep your software updated with security patches. Both operate on known IP ports that unfortunately attracts a wealth of intruders, a downside that can be attributed to both products. The good thing is that MySQL and MS SQL allow you to change the ports in case the default become too vulnerable.
Recovery
As far as the recovery goes, SQL Server has a definite advantage over MySQL, which it tends to fall a bit 'short with its MyISAM configuration. A UPS system is mandatory with MyISAM as it assumes the uninterrupted operation. Should there be a power outage, which could lead to corruption and loss of critical data. With SQL Server, data corruption is more unlikely. The data travels through various checkpoints in the transition from the keyboard to the hard drive and through the monitor. In addition, SQL Server keeps track of the process, even if the system stops so sudden.
The best choice
As you can see, both systems have their advantages and disadvantages. From our point of view, any product that allows you to be efficient is a good database; something different that is not worthy of your time and frustration. When it comes to MySQL and MS SQL, the decision all comes down to the situation and, above all, what you're trying to accomplish.
