So let’s start.


Oracle Database is a database management system produced by Oracle Corporation. This Relational Database Management System (RDBMS), manages relational data with the largest market share. It’s a database commonly used for running online transaction processing and data warehousing.

It’s relatively easy to learn – as long as you have a good handle on SQL and Linux.

Ideal for

Large organizations/corporations that handle enormous databases where stability and performance is key.

  • Stable - has been on the market for years (much longer than the rest of the list), are well aware of user requirements
  • Support - new releases with many new features that are well documented and often released
  • Supports SQL and NoSQL systems
  • Huge User Base and Developer Base
  • Linux support
  • Well tested database for large installations. It can handle a huge amount of data and perform well under load
  • It can get very expensive very quickly
  • Complexity - you don't just install Oracle
  • The system can require significant resources once installed, so hardware upgrades may be required
  • You need an expert to handle - everyday maintenance itself require a skilled resource

Easy to learn but its implementation of SQL will likely teach you bad habits that you’ll have to unlearn later.

Ideal for

Organizations that need a decent and safe database management tool for a low budget.

  • Portability with Oracle Database without much scheme changes
  • Free software that’s intuitive to install
  • Many technical, non-technical documentation online
  • It can be made to work with other databases, including DB2 and Oracle
  • There are a variety of user interfaces that can be implemented
  • Restricted for complex business logic
  • You may spend a lot of time and effort to get MySQL to do things that other systems do automatically
  • There is no built-in support for XML or OLAP
  • You need to pay for support
  • Works fine in most small or medium applications, but when data size grows, the performance degrades

  • Accenture

Requires basic SQL skills.

Ideal for

Large organizations that use several Microsoft products.

  • One of the primary purposes of Microsoft SQL Server is ensuring the security of your database, especially with a Microsoft SQL Server database administration service
  • It works very well with other Microsoft products
  • The engine offers the ability to adjust and track performance levels, which can reduce resource use
  • Microsoft SQL Server has many features that promote data restoration and recovery. Although individual tables cannot be backed up or restored, complete database restoration options are available
  • Enterprise pricing may be costly
  • Even with performance tuning, Microsoft SQL Server can gobble resources
