In the case of MS SQL, all the database objects such as views, tables, and procedures are sorted by database names. All the changes are made in memory, and nothing is actually done explicitly unless an external COMMIT command is not used.ĭatabase objects organization is different for both the databases. In the case of Oracle, every database connection is a new connection treated as a new transaction. The commands to make this process a lot more efficient are BEGIN TRANSACTION, COMMIT, ROLLBACK, END TRANSACTION, etc. MS SQL will, by default, commit and execute each command/task as a unit and roll backing is difficult. A transaction is defined as a group of operations and tasks to be treated as a single unit. The other major feature between these two databases is the capability of transaction control. The provision of grouping procedures together into packages is something that is not available with MS SQL Server. The main difference lies in the variables, syntax, and procedure handling, along with built-in functions. MS server used transact SQL whereas Oracle makes use of PL/SQL Procedural Language and a Structured Query Language. The language used in SQL Server and Oracle RDBMS is different even when they both use different forms of Structured Query Language. Key Difference between Oracle and SQL Serverīoth Oracle vs SQL Server are popular choices in the market let us discuss some of the major Difference: Head To Head Comparison Between Oracle and SQL Server (Infographics)īelow is the top 14 difference between Oracle vs SQL Server The newer version has built-in performance tuning metrics, real-time operational analytics, data visualization strategies hybrid cloud support using which the database administrators can run the same application on either on-prem or on the cloud as they deem fit to lower organizational cost. The data present inside it is usually connected, avoids redundancy, thereby providing greater data integrity. This can be used for deploying, building, and managing applications located on-prem or on the cloud. Triggers, views, stored procedures and other database objects are the ones that are taken care of by the Database Engine. The relational engine processes queries and commands, and the storage engine present in it is responsible for managing database files, pages, tables, data buffers, indexes, and transactions. The SQL Server Database Engine controls data storage, security, and processing. Scaling, rerun production workloads for both batch and online real-time user, support for virtualization techniques, VMWare support, high availability, and uninterrupted processing makes it a beautiful and elegant database to be used. The server-side memory structure is referred to as the SGA (System Global Area), which is responsible for holding cache information related to SQL commands, data buffers, log history, and user-specific information. The Database can be accessed only using a client-side program. The Oracle database feature to be used for enterprise grid computing helps in the creation of modular servers and storage where the storage mechanism is achieved by creating logical and physical structures.
