Extremely large amounts of unstructured and/or semi structured data come from different sources and relational databases can not cope with such large amounts of data in a satisfactory manner. Relational databases are mature technology many DBMSs are available, SQL is standardized, etc.
More on SQL can be found in (Rabuzin, 2011, 2014). Each DBMS has some (graphical) client program (one or more) that can be used to write queries (in SQL) in order to work with the database (for example, phpMyAdmin, Workbench, Navicat, pgAdmin, SQL Server Management Studio, etc.). Many other, complex statements are available as well, but for our purposes, we can skip the details. In order to retrieve data from one or more tables, SELECT statement is used.

The INSERT, UPDATE and DELETE statements are used for data manipulation purposes. The CREATE statement is used to create different objects in the database, as well as the database itself. SQL contains many statements to work with data.

SQL is a standardized language that is supported by all major Relational DBMS software vendors (it does not belong to any vendor in particular). In order to use a database management system, one has to be familiar with Structured Query Language (SQL). The relational model was introduced by dr.
Relations store data in a compact and organized way and redundancy and anomalies that are caused by redundancy are usually avoided. The idea of storing data into relations (tables) is quite old and relational databases have been used for over 40 years. “Relational” means that the main structure that is used to store data is a relation, or as users usually call it, a table. The majority of DBMSs are relational in nature. Many systems are available, including Oracle, DB2, SQL Server, PostgreSQL, MySQL, Microsoft Access, Neo4j, MongoDB, etc. In the same way, in order to create a database, some Database Management System (DBMS) should be used. In order to create a text file, some text processor should be used (for example, Word, Wordpad, Notepad, etc.). Actually, any list of items on a paper could be called a collection of data as well, but today it is assumed that databases are stored digitally. It is assumed that a database is stored as files on a computer. One can find more or less complicated definitions, but one could say that a database is an organized collection of data.
