There can be many challenges to the modern customer when it comes to using commercial solutions like Oracle Database.
Open source has become increasingly popular among companies to avoid vendor lock-ins and take on cost savings.
Enterprises often make a move from Oracle Database to open source PostgreSQL.
Therefore, we’ll look closely at the Oracle to PostgreSQL migration.
What Is Database Migration?
Migrating your existing SQL Server database to PostgreSQL requires planning, preparation, conversion, testing, and verification.
During the migration, you’ll need to pick the right schema, perform compatibility checks, convert incompatible objects, and test functionality.
After the migration, you’ll also need to verify that everything works correctly.
The Benefits Of Moving From Oracle Database To PostgreSQL
You may choose to move away from Oracle to PostgreSQL for several reasons.
First, PostgreSQL is free to download and use.
Second, PostgreSQL is fully open source, meaning you’re not locked into any particular vendor.
Third, PostgreSQL is highly customizable, allowing you to tailor your database to meet your needs.
Fourth, PostgreSQL is supported by public clouds, such as Amazon Web Services (AWS), making it easy to deploy.
Fifth, if you need to increase the workload, scaling to millions of transactions per second with PostgreSQL is much less expensive than scaling the Oracle Database.
Finally, because PostgreSQL is an open-source project, you can get access to all of its features, even if you don’t pay for software licenses.
The database migration process isn’t always easy.
There are several reasons why this might be true, including differences in database structure, data types, and even metadata.
When you migrate from Oracle to PostgreSQL, you need to use the correct toolset. Follow the steps below to get started.
Reason One: It’s a True Open Source Project
PostgreSQL has been around for 30 years.
It started as an academic project at Berkeley University back in 1991.
Since then, it has grown into a mature and stable piece of technology. As a result, it is used by thousands of developers and organizations.
As a result, it has become the de facto standard for databases in many different areas.
PostgreSQL is an open-source object-relational database management system (ORDBMS), originally released under the GNU General Public License (GPL).
Since its inception, PostgreSQL has grown to become one of the most widely deployed free software projects in existence today.
Its popularity stems from its ability to provide high availability, scalability, security, and reliability while remaining easy to install and manage.
The project aims to create a complete, feature-complete, general-purpose relational database management system.
PostgreSQL is a free and open-source relational database management system (RDBMS) that is built upon the concept of ACID compliance. It is widely used by developers, businesses, and universities due to its ability to handle large amounts of data.
It was originally designed for Unix platforms but is also available for Microsoft Windows and macOS operating systems.
PostgreSQL is a drop-in replacement for many proprietary databases. It supports all major programming languages, including C/C++, Java, Python, Perl, PHP, Ruby, Tcl, and others.
It provides native support for JSONB and XML types.
It also includes extensions for advanced functionality such as full-text search, spatial indexing, and geospatial queries.
Reason Two: No License and a Large Community
Oracle Database is expensive.
There are many different products available, each with its own cost.
If you’re looking for a solution to your problem, chances are there is already a product that does what you need.
PostgreSQL is free, and if you have a question about how to solve a problem, someone will likely answer it for you.
Newbies and pros dig into this list to connect, showcase, and share your solutions, technologies, bugs, new findings, and even share your emerging software.
Reason Three: Wide Support for SQL Conformance
PostgreSQL is committed to following the SQL standard.
That means that any future revisions will replace older ones.
So there is no point claiming that you’re using version X when you actually aren’t.
In SQL Server, you can create hierarchies that contain other hierarchies.
To start, you need to create a hierarchy object called a HierarchyID.
You then need to add child objects to the hierarchy.
Once you’ve done that, you can query your hierarchy like any other table.
Reason Four: Improved Performance
PostgreSQL has had many improvements since its first release in 1995.
One is the query parallelism feature, which allows users to create multiple queries at once and execute them simultaneously.
Reason Five: Excellent Scalability
You can use Oracle Database when you need a lot of processing power.
However, scaling the Oracle Database is expensive.
With PostgreSQL, you can quickly scale to millions of transactions per second.
Oracle’s database is costly and requires many resources to run.
If you’re using an Oracle Database, you’ll need to pay for all those servers, licenses, upgrades, etc.
PostgreSQL and its underlying platform can be of choice to cut costs, reduce your budget and provide you with the required services – all with moderate to minor changes.
Our experienced and highly skilled database administrators have been working with PostgreSQL for years, which means we know precisely how to complete the database migration process, how to avoid any performance issues and what you should be doing to succeed.
