Data is an integral part of our lives

Many databases are emerging nowadays. Modern companies store transactional information in these databases.

The global market for database management systems (DBMS) is estimated at nearly $79.2 billion for the year 2022.?It is projected to reach $125.6 billion by 2026, growing at a CAGR of 16.3%. For this reason, organizations are constantly looking for ways to stay ahead of the competition by collecting high-quality data faster and at a lower cost.?

Database systems are one way they accomplish with. So, to make things easier, I have combined research across the Internet and with my personal experience,?the most popular and emerging databases are:

ORACLE

Oracle is a well-known database management system gaining resistance due to its scalability and high performance.?It is written in assembly languages such as Java, C, and C++ and includes a widely used RDBMS.?

• It takes up less space than other databases and processes data faster.
• This multi-model database system is produced and marketed by Oracle Corporation.
• Oracle is still a popular database as the most recent release, i.e., 21C has added many innovative features that created a grip toward future use.
• It saves space and processes data more quickly.

MongoDB

• MongoDB is an Open-source, object-oriented document-based database that stores high-volume data.

It stores data inside a collection of documents rather than in rows and columns like in other databases.

• Before MongoDB, it wasn't easy to load and access data into RDBMS through object-oriented programming languages.??

As a solution, MongoDB’s developers added Document Data.

It is a scalable, flexible database platform that overcomes the relational database approach.

?It provides users unparalleled flexibility through horizontal scaling and load balancing capacities.

• MongoDB has become quite popular in the last few years, with the number of users growing at almost the same rate as PostgreSQL.
• Some of the famous Companies Currently using MongoDB Database are:
