Oracle SQL Training
SQL Structured Query Language) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), SQL offers two main advantages: first, it introduced the concept of accessing many records with one single command; and second, it eliminates the need to specify how to reach a record, e.g. with or without an index.
The scope of SQL includes data query, data manipulation (insert, update and delete), data definition (schema creation and modification), and data access control. Although SQL is often described as, and to a great extent is, a declarative language (4GL), it also includes procedural elements.
SQL was one of the first commercial languages for Edgar F. Codd’s relational model, as described in his influential 1970 paper, “A Relational Model of Data for Large Shared Data Banks”. Despite not entirely adhering to the relational model as described by Codd, it became the most widely used database language.
SQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987. Since then, the standard has been revised to include a larger set of features. Despite the existence of such standards, most SQL code is not completely portable among different database systems without adjustments.
Structured query language helps you manage data in a relational database. Relational databases use a system of tables to store individual pieces of information. They are known as “relational” because the data is organized based on the relationships between items.
Few key features of Oracle SQL is-
-
Grouping Transactions
- The ability to group several transactions into the same batch for processing sets Oracle apart from its competitors.
-
Improved Performance
-
In addition to batch processing of transactions, Oracle offers other methods of improving your database’s performance. You can use multiple servers to work on the same database with the Real Application Cluster feature. This can significantly increase your processing power for only the price of an additional server. Oracle SQL also gives you more options to fine-tune the operation of your database to suit the capabilities of your server.
