Oracle vs Google Cloud Spanner: What are the differences?
Developers describe Oracle as "An RDBMS that implements object-oriented features such as user-defined types, inheritance, and polymorphism". Oracle Database is an RDBMS. An RDBMS that implements object-oriented features such as user-defined types, inheritance, and polymorphism is called an object-relational database management system (ORDBMS). Oracle Database has extended the relational model to an object-relational model, making it possible to store complex business models in a relational database. On the other hand, Google Cloud Spanner is detailed as "Fully managed, scalable, relational database service for regional and global application data". It is a globally distributed database service that gives developers a production-ready storage solution. It provides key features such as global transactions, strongly consistent reads, and automatic multi-site replication and failover.
Oracle and Google Cloud Spanner can be categorized as "Databases" tools.
