Structured Query Language
The Oracle Autonomous Database Service provides a managed database server, running in the Oracle Cloud. Each instance can be optimized for transaction processing or data warehouse activities. Because Oracle provides a free tier, this service is ideal for learning the principles of relational database management. The aim of this site is to be a resource for individuals learning the power of relational technology.
Currently, the Oracle Cloud Free Tier provides two instances of the Oracle Autonomous Database to everyone. Because these are provided at no charge, there are some limitations. Each database is limited to 20 gigabytes of storage and 20 simulteneous connections. This is not just an educational resoruce as the free-tier license allows these to be used for commercial purposes.
The tutorials at this site will guide you through the setup and use of a free instance of an Oracle Autonomous Database, how to manage data with Structured Query Language, and how to connect to your database in several popular programming environments.
