Over the years, database engines have evolved drastically. Today we have plenty of database engine options to choose from with each database engine offering specific solutions to meet the demands of organizations.
The simple definition of a database is that it is an orderly collection of structured data that is stored in a computer. It is taken care of by a database management system (DBMS) and is associated with the field of software development. For software developers, it is extremely crucial to identify which database they should use for particular software architecture. Since new database engines are emerging every now and then, developers have an abundance of database engines to choose from.
There are two types of central databases, namely SQL & NoSQL. SQL is a programming language used by all relational databases to manipulate queries and define data to control supply access. SQL was launched at IBM by Donald D. Chamberlin and Raymond F. Boyce in the early 1970s. On the other hand, a NoSQL database gives a medium for storing and retrieving the modeled data.
10 Best Database Engines
While having so many databases, it will be technically challenging to find the best one. Therefore, we will share some of the best and trending database engines for building top-quality projects.
Oracle is one of the most popular database engines. The reason behind the widespread popularity of Oracle Database is that it is easy to use and comes with well-written documentation. Oracle is the number one commercially assisted database and of the most used relational database management system. The latest Oracle release (21.c) has added many innovative traits to make a winning option in the future.
Oracle Database 12c provides numerous features that allow customers to meet specific requirements, such as scalability, performance, high availability, and data warehousing. Oracle Database delivers excellent performance, especially when challenged with demanding tasks. You will get the ACID test, which is an additional tool used to check data integrity. Oracle offers flashback technology which provides many advantages as follows.
Flashback Database: You can restore the entire database to a particular point-in-time with Oracle optimized flashback logs.
Flashback Table: You can quickly recover tables to a precise point-in-time.
Flashback Drop: You can easily recover a suddenly dropped table. It will restore the dropped table with all of its indexes, triggers, and Recycle Bin constraints.
Flashback Transaction: You can undo the effects of a single transaction.
Flashback Query: You can easily query any data at some point-in-time in the past. This feature can be used to view and logically restore corrupted data that may have been changed accidentally.
- Oracle is based on the PL/SQL programming construct.
- It supports peer-to-peer fellowships aid to solve puzzles.
- Oracle database signifies security and guarantees that user data is not meddling with prompt updates.

PostgreSQL is an enterprise-based open-source database management system. It carries advanced data type and performance optimization features. Besides, PostgreSQL is highly scalable for object-relational databases. PostgreSQL efficiently runs on Windows, Linux, OSX, and several other operating systems. PostgreSQL is also popularly known as Postgres.
Some of the main features of PostgreSQL are, tablespaces support, stored procedures, joins, triggers, views, etc. Significant improvement in PostgreSQL 10 comes from logical replication that uses publish, declarative table partitioning, and strong password authentication. This password authentication is based on SCRAM-SHA-256.
PostgreSQL can quickly run on websites and web apps as a LAMP stack addon. Besides, you can also access the source code of PostgreSQL as it a free and open-source RDBMS.
- PostgreSQL has support for multi-version concurrency control.
- PostgreSQL has a large number of interface tools.

- PostgreSQL provides multi-version concurrency control (MVCC)
- There have been some cases where many software developers have faced less mature replication software issues.
- The actual configuration can be daunting due to its comprehensive functionalities.
MongoDB was developed by MongoDB Inc. in 2007. MongoDB is a document database that comes with numerous features. It makes software development easier with its scalable and flexible nature. It presents a simple model for developers to learn and use. The great thing about MongoDB is that it comes with significant abilities required to meet the most complex requirements in software development.
MongoDB is considered to be the best dynamic query along with defining indexes. It uses a flexible structure that can be quickly modified and extended. Programmers will be able to write without downtime issues.
MongoDB fortifies OSX, Linux, and Windows, although the DB size is restricted to 2.5 GB on a 32bit system. However, it’s essential to have eyeballs on MongoDB’s advantages. It facilitates faster access of the data due to its feature of internal memory for storage. It is a NoSQL database that is 100% secure because of no SQL injection. Besides, MongoDB supports the search by regex and fields.
