Oracle and SQL are two related technologies in database technology. They have a wide range of applications and are often used for data management and processing.
First, let us understand the definitions and functions of the two. Oracle is a relational database management system (RDBMS) developed by Oracle Corporation and widely used in enterprise-level applications. It supports SQL language as a standard technology for querying and processing data. SQL is a structured query language, a standardized language used to access and operate relational databases. It is often used for operations such as querying, updating, inserting and deleting data records.
So what is the difference between Oracle and SQL? First of all, at the application level, Oracle is a database management system, and SQL is a language used to operate and query relational databases. Secondly, in terms of statement structure, Oracle contains many functions that are not just SQL, and has added many extensions based on SQL. Oracle has added many independent language extensions based on SQL, such as PL/SQL and QBE. These extended functions give Oracle a higher level of database management capabilities, giving it an advantage when dealing with unstructured data.
Secondly, Oracle and SQL are also different in performance and application scenarios. Because Oracle has more advanced functions and a more complete database management and maintenance system, Oracle is more suitable for the management of enterprise-level applications and large databases, such as more complex application systems and their underlying databases. SQL is suitable for small databases and Web applications with relatively simple structures. At the same time, SQL is also used in database management of some large enterprise-level applications.
In addition, Oracle and SQL are also different at the communication level. Oracle is developed by Oracle Corporation and uses its own communication protocol for communication (Oracle Net Services). SQL is a standardized query language that can be used by every SQL implementation, and the communication protocol is simpler and more general.
Taken together, Oracle and SQL are two different technologies in database technology. They have different functions, applicable scenarios, statement structures, communication protocols and other characteristics. Although they have some commonalities and intersections in some aspects, which technology to use depends on the specific application scenarios and requirements.
