Anyone wanting to earn a database degree or get database administrator certification will quickly find that SQL training is a must. SQL (Structured Query Language) is a standardized language in which all database transactions take place, whether you're using a graphical interface for database administration or programming your own SQL code.
Because a database can be used to store and manipulate many complex sets of data, it is possible to filter information according to specific criteria or perform complex calculations across multiple data sets. With SQL training, a database administrator retrieves customized information, as well as creates, alters or drops (destroys) the databases themselves.
The Development of SQL
In the 1970s and 1980s, when relational databases were coming into extensive use throughout government, large companies and other industries requiring massive data storage, the first language for structuring database queries was also developed. It was an IBM creation called SEQUEL (Structured English Query Language), and it opened the doors for a variety of similar query languages by other companies seeking to harness the power of databases.
Database Degrees and SQL Training
Job seekers interested in working with databases should think seriously about earning a database management degree or other credential in order to gain a solid working knowledge of SQL. If you do choose to delve into SQL training, you'll learn about the different types of commands used to create and destroy databases (Data Definition Language commands) and those used to insert and modify data and conduct queries for information retrieval (Data Manipulation Language commands). Training for database management or administration will also include learning database management software, such as Microsoft Access or MySQL.
Show Me the Data
To a large extent, your marketability in the field will depend on your knowledge of fundamental database administrator skills, such as overseeing the organization and storage of data, creating and modifying databases, managing database security and troubleshooting problems. SQL training and a database degree provide an important leg up, because you'll be able to efficiently customize database transactions to suit your needs and those of your company.
