An Oracle database can run on all major platforms, including Windows and networking protocols. Oracle fully supports all industry standards and provides full support to developers. Other benefits are that Oracle supports online backup and recovery and has a wealth of development tools, covering various stages of the development cycle.
Oracle supports large databases, data type support numbers and characters, and it provides data to support object-oriented database storage. An Oracle database has the ability to manage multiple databases using a two-phase commit protocol. Oracle supports cursors, which helps to make programming easier. It also performs each transaction separately, and the result of each transaction is invisible to other transactions until it is complete, which increases the security of data.
One major disadvantage of Oracle database is its complexity. Using Oracle is not ideal if the users lack the technical ability and know-how needed to work with Oracle databases. It is also not ideal to use Oracle if an organization or individual is looking for an easy-to-use database with basic features.
Oracle is only useful when large databases are needed. It is not ideal for small or mid-sized companies where small databases are needed. In such cases, using MySQL is more cost effective.
