Do you want to learn the top benefits of moving from Oracle to PostgreSQL and why should your company do this move?
Below are the 30 top benefits of making this move.
Here Are The 30 Top Benefits Of Moving From Oracle To PostgreSQL
1. Considerable Cost Reductions:
The cost of running PostgreSQL is significantly less than Oracle.
For example, the cost of running Oracle database on Amazon Web Services is $0.08 per hour.
On the other hand, the cost of running PostgreSQL on AWS is only $0.02 per hour.
This means that even though you’ll pay more for the service, you’ll save money over time.
2. Scalability:
With PostgreSQL, you can scale up or down easily without affecting the database.
In fact, you can add additional servers to your cluster and continue working.
When you need to scale back, all you need to do is remove one server from the cluster.
3. Security:
You don’t have to worry about installing patches or updates.
A PostgreSQL instance will automatically update itself when new versions are released.
This ensures that your database always stays secure.
4. Availability:
PostgreSQL is highly available.
All data stored in PostgreSQL is replicated across multiple nodes so that any node failure won’t affect the operation of the database.
5. Reliability:
PostgreSQL uses MVCC (Multiversion Concurrency Control).
This feature allows you to read uncommitted changes made by another transaction.
This prevents data loss and makes sure that your application doesn’t crash.
6. Performance:
PostgreSQL performs better than Oracle.
According to some studies, PostgreSQL is 2x faster than Oracle at reading data.
And it is 3x faster than Oracle at writing data.
7. Usability:
PostgreSQL is easier to manage than Oracle.
It is simple to set up and maintain.
Unlike Oracle, which requires extensive training to administer, PostgreSQL is intuitive and straightforward.
8. Community Support:
PostgreSQL is supported by a vibrant community of developers, administrators, and users.
They offer support through online forums, email lists, and social media channels.
9. Open Source:
PostgreSQL is an open source project.
Anyone can download the software and modify it as needed.
This gives you complete control over how the product evolves.
10. Free:
PostgreSQL is completely free.
It comes with no licensing fees or subscription charges.
11. Extensible:
PostgreSQL is extensible.
You can extend its functionality by developing custom extensions.
These extensions are called “pluggable” modules.
12. High Availability:
PostgreSQL is built to be highly available.
Any node failure won’t affect your database.
13. Multi-Platform:
PostgreSQL works on Windows, Linux, macOS, and FreeBSD.
So you can run it on almost every platform.
14. Easy Installation:
PostgreSQL installation is very easy.
You just need to install the appropriate packages and then start the database server.
15. Upgrades:
If you decide to upgrade your existing databases to PostgreSQL, there’s no need to shut down the system.
Just make the necessary changes to the configuration files and restart the database server.
16. Flexible Architecture:
PostgreSQL supports both shared and distributed architectures.
Shared architecture is used when you want to share data among several applications.
Distributed architecture is used when you have many different servers storing data.
17. SQL Language:
The SQL language is similar to other relational databases such as MySQL and Microsoft Access.
However, PostgreSQL has added features like full text search, JSONB, and GIN indexing.
18. Replication:
PostgreSQL supports replication.
Data is replicated across multiple nodes for high availability.
19. Scalability:
PostgreSQL is scalable.
You can add more nodes to increase performance.
20. Customization:
PostgreSQL lets you customize everything from the user interface to the underlying storage engine.
21. Security:
PostgreSQL offers security features like authentication, authorization, encryption, and access controls.
22. User Management:
PostgreSQL provides a flexible way to create, delete, edit, and assign roles to users.
23. Database Tools:
There are various tools that help you manage and monitor your databases.
For example, you can use pgAdmin III to connect to your databases and perform queries.
24. Backup And Restore:
You can back up your databases using scripts or dump files.
You can also restore them easily if something goes wrong.
25. Relational Features:
PostgreSQL uses the same concepts of relations, tables, columns, indexes, triggers, views, sequences, etc., as in Oracle.
26. Full-Text Search:
PostgreSQL includes full-text search capabilities.
This allows you to search documents stored in the database.
27. JSONB:
PostgreSQL supports structured data types like JSONB.
This makes it easier to store complex objects in the database.
28. Foreign Keys:
PostgreSQL supports foreign keys.
This helps you maintain referential integrity between tables.
29. Transactions:
PostgreSQL supports transactions.
They allow you to commit all the updates made to a table atomically.
30. Stored Procedures:
PostgreSQL supports stored procedures.
These functions can be called by other programs.
