SQL Certification Trainingby Lauren Perez-Asencio
SQL stands for "structured query language," a database communication language used by database management systems such as Sybase, Microsoft SQL Server, Oracle, Ingres and Access. SQL is divided into two classes, Data Design Language (DDL) and Data Manipulation Language (DML). DDL creates, modifies and removes tables, while DML executes file management activity by storing and fetching data within tables.
SQL certifications are for IT professionals wanting to establish themselves as credible in the language. , Introductory courses introduce newcomers to SQL and highly specific courses provide specialized education.
Several computer system companies provide SQL certification using external SQL software or their own SQL database programming systems. The companies offer basic SQL education but become more specific the higher the level of education desired. SQL certification courses are available online.
SQL certification training usually takes a few days and costs vary according to the class and certification provider. Oracle, for example, offers certification programs that cost between $1,200 and $1,800 per course, as of 2010.
