Oracle vs PostgreSQL Comparison

  

The War has began

Oracle Database is a commercial, proprietary multi-model database management system produced by Oracle Corporation, and the largest relational database management system (RDBMS) in the world. While Oracle remains the #1 database on the market, its popularity has steadily declined by over 18% since 2013. What’s causing this massive shift? This all is happening due to rise of open source databases. One database in particular is causing a huge dent in Oracle’s market share – open source PostgreSQL.

When comparing the two solutions, things to consider are:

• How easier to use it is,
• How easily you can setup and administer database
• How much this database fulfills your requirements
• How much performance efficient it is
• How much you have to pay for it
• How much support is available over the internet
• How much availability it gives to you
• Is your data secure inside this database
• And many more…..
