Top 10 Free Relational Database Management Systems (RDBMS)
Companies handle data and need to utilize an effective database management system (DBMS) to organize their data on a daily basis. The best DBMS allows users to keep accurate records of data, organize, manipulate, and retrieve data. Companies need a system that allows them to access the information they want at the right time, identify and manage relationships between different sets of data, update existing data, delete unwanted or outdated data, and perform search queries at any given moment. There are different types of database management systems, but the relational database management system (RDBMS) is the most popular type of DBMS. The RDBMS has been the predominant DBMS for more than 40 years. With the right RDBMS, companies can create and manage relational databases with all kinds of structured data such as employee data, customer data, sales data, phone numbers, census records, legal records, and library catalogs.
Top Free Relational Database Management System (RDBMS): Db2 Express-C, SQLite, CUBRID, Firebird, Oracle Database XE, MariaDB, Sequel Pro, PostgreSQL, MySQL, SQL Server Express are some of the Top Relational Database Management System (RDBMS).
What are Relational Database Management System (RDBMS)?
In 1970, Edgar Codd wrote a paper that established the theoretical basis for modern-day relational databases. These databases are based on the relational model, structured query language (SQL), and ACID transactions. Relational databases organize data into tables with rows and columns. The term relational means that values within each table are related to each other. Rows are also known as records and one table can have hundreds, thousands or millions of them. Columns or fields have a descriptive name and a specific data type.
Relational database users use a relational database management system to manage these databases. An RDBMS can be defined as a database program that allows database users to perform different queries on relational database data. It’s the software that allows you to add data, update the database, search for values, and retrieve information. RDBMSs can also provide visual representations of data. RDBMSs use structured query language to execute queries.
- Data Storage – One of the key features of an RDBMS is the ability to store data in tables. Each table consists of many rows and columns that store the actual values. Tables provide a rigid structure for storing structured data.
- SQL Commands – An RDBMS allows users to perform queries with the help of SQL commands. The system uses different commands to store new data, modify existing data, perform searches, and retrieve data based on the user’s input.
- ACID Transactions – Another important feature of an RDBMS is the ability to ensure ACID (atomicity, consistency, isolation, durability) transactions. This feature ensures that all transactions are complete, consistent based on all defined rules, and free from any problems associated with errors, system crashes, and power loss.
- Cross-Platform Use – Some RDBMSs are available on multiple platforms including Android, iOS, Solaris, Linux, Mac, VxWorks, Windows, and Unix. This means RDBMSs are available on smartphones, PDAs, MP3 players, tablets, computers, and set-top boxes.
- Replication and Partitioning – The best RDBMSs include a feature that allows users to partition tables and replicate data. Database users can subdivide tables and indexes into smaller pieces that are easy to manage.
Some of the benefits include:
- Partitioning and replication schemes help businesses to improve their overall performance by meeting every business need.
- ACID transactions ensure data integrity, completeness, and accuracy.
- Multiple users can use the system simultaneously.
- Easy to understand and use – SQL uses simple English language keywords.
- Availability and affordability.
