Microsoft SQL Server vs. Oracle: The Same, But Different?

As we get to know Microsoft SQL Server and Oracle technologies have many similarities in the functionality that they give. They are both relational database management systems; however, they have many differences as well. When you know all the circumstances following a career path and keeping expectations accordingly becomes easier.

There are many various relational database management systems out there. You have heard about Microsoft Access, Sybase, and MySQL, but the two most popular and widely used are Oracle and MS SQL Server. Although there are many similarities between the two platforms, there are also several key differences. In this blog, I will be taking a look at some in particular, in the areas of their command language, how they handle trade control and their organization of database objects.

Understand Each Technology Microsoft SQL Server vs. Oracle:

About Microsoft SQL Server

Being a database product of Microsoft MS SQL enables users to SQL queries and execute them. It is one of the most steady, secure and reliable database solutions. The technology gives a wide range of transaction processing, business intelligence and analytics in corporate IT environments.

Features of Microsoft SQL Server:

• It maintains BI tools, SQL Server Management Studio, Profiler, and Database Tuning Advisor.

• It maintains "online" support and documentation, and LIVE product support.

• It gives advanced customization option for datatype mapping, deletes and renames objects.

• It displays alerting messages, errors, and immigration in a progress window.

• A single and integrated environment for SQL Server database Engine management and permitting.

• An activity filtering and monitoring feature and automatic refresh.

• When a dialog is open, it provides the path to multiple tools, resizable dialogs.

• Exporting and Importing from SQL Server Management Studio.

About Oracle Database

Oracle database is an RDMS system of Oracle Corporation and software that is developed around the relational Database Framework. It enables the data objects to be accessed by the users who are using SQL language. Oracle is only a scalable RDBMS architecture and is widely used all over the world.

Oracle is one of the most prominent vendors in the IT market, and its flagship RDBMS product is generally known as the Oracle Database.

Features of Oracle Database:

• When related to databases it has the ease of recovery.

• It let you turn the platforms at any time.

• The RDMS system is provided to handle immense data.

• It allows for scale-out and scale-up strategies.

• It has a guide for test hardware and OS particular virtualization technologies.

• The database enables you to rerun actual production workloads, including user and batch workloads in test environments.

• The standby database can serve as a primary database, and the central database becomes inaccessible.

• It is based on testing or backups, read-write and decreases the load on the primary database.

Microsoft SQL Server vs. Oracle: Some Different Tools

1. Language

Perhaps the most apparent distinction between the two RDBMS is the language they use. Although both systems use a variant of Structured Query Language or SQL, MS SQL Server uses Transact SQL, or T-SQL, which is an increase of SQL initially developed by Sybase and used by Microsoft. Oracle, while, uses PL/SQL, or Procedural Language/SQL. Both are different “flavors” or languages of SQL, and both languages have complex grammar and capabilities. The main distinction between the two languages is how they control variables, stored procedures, and built-in functions. PL/SQL in Oracle can also group procedures commonly into packages, which can’t be done in MS SQL Server. PL/SQL is complex and probably more powerful, while T-SQL is much more straightforward and easier to use.

2. Transaction Control

Another one of the most significant differences between Oracle and MS SQL Server is transaction control. For instance, a collection of SQL queries changing records that all must be updated at the same time, where a failure to update any single records among the set should result in none of the documents being updated. By default, MS SQL Server will perform and perform each command/task individually, and it will be difficult or unlikely to roll back changes if any errors are encountered along the way. Within a transaction, ROLLBACK will abandon any changes made within the transaction block. When used adequately with error handling, the ROLLBACK allows for some degree of security on data corruption. After a COMMIT is issued, it is not possible to roll back any further than the COMMIT command.

Within Oracle, on the other hand, any new database connection is treated as an original transaction. As doubts are executed and commands are issued, changes are done only in memory, and nothing is committed until an explicit COMMIT statement is given with a few differences related to DDL commands, which comprise implicit commits, and are performed immediately. After the COMMIT, the next authority issued essentially initiates a new transaction, and the process begins again. This gives greater flexibility and helps for error control as well, as no changes are committed to disk until the DBA explicitly issues the government to do so.

3. Organization of Database Objects

MS SQL Server holds all purposes, such as tables, views, and procedures, by database names. Users are charged to a login which is granted accesses to the specific database and its objects. Also, in SQL Server each database has a separate, unshared disk file on the server. In Oracle, all the database targets are grouped by schemas, which are a subset group of database objects and all the database objects are shared amongst all schemas and users. Also though it is all shared, each user can be limited to specific schemas and reports via roles and permissions.

In short, both Oracle and MS SQL Server are dominant RDBMS options. Although there are several differences in how they work “under the hood,” they can both be used in roughly similar ways. Neither is accurately better than the other, but some conditions may be more favorable to a particular choice. Either way, Segue can support these systems and help to make recommendations on how to improve, upgrade, or keep your critical mission-critical infrastructure to make sure that you can keep your focus on doing business.
