How to Learn Oracle

Do you ever wonder how SQL databases begin being used across the world in real-time applications? While SQL was a theoretical concept of structuring and organizing data, how did it enter the industry for use in end-user products? The answer is Oracle — the first relational database that supported the Structured Query Language (SQL) design. SQL has grown to become an industry-standard in today’s times.

In this guide, we’re going to talk about how to learn Oracle and what resources you can use to master it.

What You Need to Know About Oracle

Oracle is a relational database management system with a wide range of possible uses. It is a full-fledged database management solution, with powerful querying capabilities. Oracle is commonly known as Oracle database or OracleDB. Oracle is designed for enterprise-level grid computing. This means that Oracle is built to withstand tremendous traffic and operations in real-time scenarios. Some of the key features of the technology that make applications robust and scalable are:

  • Cross-platform. Oracle is one of the few database systems that work on a number of platforms. You can easily run Oracle databases on Windows, Unix, and Linux environments.
  • Networking. Given the cross-platform support by Oracle, powerful networking capabilities are built-in for making internal communications across varied platforms smoother.
  • ACID Compliant. OracleDB follows the ACID compliance, which makes it reliable and robust.
  • Partitioning. Oracle databases support partitioning, which is a high-performance feature that allows users to divide large tables into different pieces and distribute these pieces across multiple storage devices.
  • Memory Caching. The memory caching feature of Oracle allows scaling up a large database that can still perform high-speed operations. 
  • Clustering: Oracle supports RAC (Real Application Clusters) which ensure high availability and keeps the system up and running without interruption of services even if servers fail.

These are only a few of the many things the technology offers. As you learn more about Oracle, you’ll become aware of more things you can use to create more reliable and powerful data stores.

Skills Needed to Learn Oracle

To learn Oracle, it is favorable to have a preliminary understanding of database management. 

You are not expected to be an expert in databases to understand Oracle, but having a prior understanding of the concept will help you easily get started. Having some experience with any other database management solution is a bonus.

Why You Should Learn Oracle

If you are looking to build applications that will scale big, you need to know how to design reliable database management solutions. On top of that, you also need to know how to ensure enterprise-level security and reliability. Oracle is one of the most common alternatives for storing huge volumes of application data, so it is an added advantage if you know how Oracle works to build applications faster.

If you are looking to process and analyze data for analytics purposes, Oracle is one of the best available alternatives. Due to its powerful querying capabilities and organized structure, Oracle finds its use in data processing jobs. Also, considering the huge community backing Oracle, it is only wise to learn Oracle as a database management solution.

How Long Does It Take to Learn Oracle?

If you have some prior experience in designing and building databases, one to two weeks of dedication to written as well as visual content should be sufficient to master the concepts of Oracle. If not, you can expect a time of two to three weeks to cover the topics in all its depth.

All in all, you can expect to devote six to eight hours daily for a period of one to two months to get a good grip on the technology. Mastering any technology is no easy job, and the same goes for Oracle. To start building real-life applications that use Oracle as their database management solution, you can expect to spend about two to three months working on the ins and outs of the technology.
