Significant differences between MS SQL Server and Oracle Database

Specialists from reliable RemoteDBA.com companies point out the following key differences between MS SQL and Oracle Database.

Parameters MS SQL Server Oracle Database
Manufacturing Company Microsoft Corporation owns, manufactures, and markets this database product. Oracle Corporation owns, makes, and sells this database.
Syntax Uses relatively simple syntax in which end-users can understand and operate. Uses comparatively sophisticated yet effective syntax
Download End-users can download the evaluation version with 120 or 180 days via www. Micrsoft.com/sqlserver. End-user can obtain the opensource version by downloading it from otn.oracle.com.
Operating system platforms for support Users need a Windows Server to install this database. However, they can connect and use the 2017 onwards versions on the Linux operating system. It is versatile and compatible enough to operate on a diverse range of operating systems.
Language MS SQL executes queries using transact SQL. It uses Oracle Corporation’s PL/SQL database language.
How to schedule jobs SQL Server Agent feature allows end-users to schedule jobs. Users can schedule jobs using the Oracle Scheduler or Oracle Enterprise Manager (OEM) feature.
Installing indexes for bit mapping MS SQL Server does not contain any keys, features, or functions for indexing bit maps. Oracle contains reverse keys for bit map indexing.
Query Optimizations End-users cannot optimize queries with MS SQL Server. End-users can optimize queries using the Star query optimization feature.
Triggers End-users have the option of using numerous ‘after’ triggers. End-user can operate a wide range of both ‘before’ or ‘after’ triggers.
Troubleshooting support End-user can download free technical notes, scripts, and bug descriptions resolving the problems they face using MS SQL. End-users have to pay a charge for the technical support they receive depending on their severity.
Rollback MS SQL Server does not allow end-users to roll back at any time during transaction processing. Oracle Database allows end-users to roll back at the time of transaction processing.
Concurrent accesses MS SQL Server does not permit end users concurrent accesses during transaction processing as extends wait time. Oracle database does allow end-users concurrent accesses, and wait time is relatively short.
Value change End-users can change value immediately before a commit with MS SQL Server. End-users cannot change the value before a commit.
Method MS SQL Servers operates on row and page-blocking technique. The database does not allow end-users to read a page when blocking it. Oracle Database creates a backup of the original data. This enables end-users to read and modifies it at the same time.
Error handling MS SQL Server processes and executes each query command separately. This makes it difficult for end-users to rectify their error during transaction processing. Oracle regards every database the end-users create as a sperate and new transaction.
Automation Support SQL upgrade advisor provides end-users with instant automation support. The database upgrade assistant allows end-users to avail hassle-free automation support.
Parallel Execution In MS SQL Server, end users can only execute INSERT, UPDATE, and Delete query statements serially. In Oracle Database, end-users can execute relevant INSERT, UPDATE, MERGE or DELETE query statements simultaneously.
Backup MS SQL Server provides users with full, incremental, or partial backup options. With Oracle Database, end users can opt for differential, full, incremental, or file-level backup.
Protection End-users can activate login authentication features either at the instance or database level. Users can activate authentication features through their OS roles or database credentials.

In conclusion, it can be said that businesses should select the best database products according to their specific needs. In doing so, they need to consider their budget allocation, relevant maintenance costs, support, and security features. In this way, they can get the best server for their needs.
