A relational database matches data using common characteristics found within the data set. The resulting groups of data are organized and are much easier for people to understand. In such a database the data and relations between them are organized in tables. A table is a collection of records and each record in a table contains the same fields. Certain fields may be designated as keys, which means that searches for specific values of that field will use indexing to speed them up.
The term relational database was originally defined by Edgar Codd, a British computer scientist, whilst working at IBM Almaden Research Center. He recognized that the concept of a relational database could be derived from the principles of relational algebra and relational calculus.

A database is a vital system for any organization that stores mission critical information. The continual failure of a company’s database system can only lead to the demise of the organization – companies cannot do business without a working database system.
To provide an insight into the quality of software that is available, we have compiled a list of 10 open source RDBMS. Hopefully, there will be something of interest here for anyone who wants to store data in an efficient way.
Now, let’s explore the 10 open source RDBMS at hand. For each title we have compiled its own portal page, a full description with an in-depth analysis of its features, together with links to relevant resources
