SQL Database
SQL or Structured Query Language is a type of programming language often specially made for database creation and management. It is made to perfectly manage and retrieve data from a RDBMS or relational database management system, a complex type of database that is widely used in storing huge amounts of data that are related to each other.
A unique feature of SQL is its ability for a database programmer to create and modify an SQL database schema. At the same time, it also allows easy control and management over a database object. Unlike the C or BASIC (Beginner’s All-Purpose Symbolic Instruction Code) programming language, SQL is a set-based language. Aside from that, it is also a declarative query language that have additional extensions. These extensions make the language more functional and powerful.
This programming language is further divided into different elements, known as language elements. These elements affect both the data and the schema in the database. Such queries to the database are capable of retrieving data from it. It can also retrieve various types of data like tables and scalar values, making it very handy in providing various types of data needed. It is also very flexible in terms of manipulating data that has to be stored or retrieved. Conditions or clauses can be crafted so that the data that will be returned from the database is the most relevant one.
Among the elements, the queries are the most common operations in the SQL database. It is performed with a declarative keyword SELECT, which retrieves the data from a table. However, the SELECT query has no standard effect on the stored data. In some cases, the SELECT query has an effect in the database similar to Microsoft SQL Server’s SELECT INTO.
Although the standard SQL is functional in many ways, a number of critics suggest that it lacks cross-platform portability between the vendors or database system. Most systems do not implement the entire SQL standard due to its complexity and size.
