• Standard Edition: It does provide all facilities offered in Standard Edition One. Additionally, it provides greater machine support and Oracle Real Application clustering service.
• Enterprise Edition: This edition is packed with features such as security, performance, scalability, and availability required for highly critical applications involving the processing of online transactions.
• Express Edition: It is an entry-level edition that is free to download, install, manage, develop and deploy.

Features of Oracle

Following features are offered by Oracle’s database to meet the requirements of powerful database management: 

• Scalability and Performance: Features like Real Application and Portability makes Oracle Database scalable as per the usage. In a multiuser database, it is important to control the data consistency and concurrency, which are contemplated by Oracle. 
• Availability: Real-time applications demand higher data availability. High performing computing environments are tend to provide data availability all the time. Data is available during the time of planned or unplanned downtimes or failures. 
• Backup and Recovery: Its layout contains complete recovery features to recover the data from almost all kinds of failures. If any failure happened, the database needs to be able to recover within no time for high availability. Unaffected parts of data are available, whereas the affected ones are getting recovered. 
• Security: Data security is always the top priority. Oracle offers mechanisms that control data access and usage. Implementing authorization and controlling user action can restrict unauthorized access and allow distinct access to the user.
