Relational Database Software Overview
What is Relational Database Software?
A relational database presents information in tables with rows and columns. A table is referred to as a relation in the sense that each row contains data that is related to a single entity , while each column represents different keys or concepts. When each row in a table is different, it is possible to use one or more columns to identify a particular row. There is always a “primary key” which serves as the unique identifier for each entity or record. For example, in the case of a table of company employees, the primary key might be employee number.
Data is retrieved from the table using a specialized language called Structured Query Language or SQL. SQL allows users to query the data using SELECT statements and WHERE clauses. A group of SQL statements can be called as a mini-program or executable which is called a stored procedure.
SQL is a widely understood language with a deep bench of practioners in the marketplace. For this reason, tools using SQL are being developed to query non-relational big data stores like Hadoop, which use less well known, and harder to use, interfaces to retrieve data.
