In this article, in our “Beginners Corners” series of articles, you will learn what are Relational Database Management Systems (DBMSs) and the SQL Server Data Platform.
What are Relational Database Management Systems (RDBMs)?
Relational Database Management Systems, also abbreviated as RDBMSs, are systems which are based on the relational model of data. The approach when using RDBMSs, is to manage data using a structure and a language, the well known Structured Query Language (SQL).
Among other, Relational Database Management Systems are mainly used for storing, organizing and retrieving data, using tables.
The below image, illustrates 2 tables (“employees” and “location”), along with a relationship between them, that uses the “id” column in the “location” table and the “locationID” column in the “employees” table, in order to form a relation between these 2 tables. In this relationship, the column “locationID” in the “employees” table, serves as “foreign key”, that is a column that references the primary key in another table.
Examples of Popular Relational Database Management Systems:
- Microsoft® SQL Server®
- Oracle® Database
- MySQL®
- PostgreSQL®
- SQLite®
- … and more!
Differences Between Relational Database Management Systems
The majority of RDBMSs, provides functionality as defined in the different standards, for example in ANSI SQL, as well as, additional functionality.
Examples of additional functionality offered in different RDBMSs, includes additional functions, system stored procedures, system catalogs, etc.
Moreover, each RDBMS might include additional features and components. For example, SQL Server, besides the standard functionality, it extends its functionality with Transact-SQL (T-SQL), In-Memory OLTP, SSIS, SSRS, SSAS and more.
