SQL is not Microsoft. SQL is a structured query language. There are different products of SQL. One of the products of SQL is Microsoft products. Let me compare like this, SQL is a laptop and there are different companies whose product is laptop like apple, dell, hp. In the same way, SQL is a language for a database, Companies like Oracle have MYSQL, IBM have DB2 and Microsoft have SQL-Server or MS Server.
SQL is a database
A database is an organized collection of data. A database is an electronic system that allows data to be easily accessed, manipulated and updated. We store data in form of tables inside a database. Data in form of rows and columns is called as a table. We store structured data in a database. Let’s take the example of Facebook. It needs to store, manipulate and present data related to members, their friends, member activities, messages, advertisements and lot more on their databases. All the Relational Database Management Systems like Oracle, SQL Server, MySQL, MS Access, DB2, Sybase, Informix, and Postgres use SQL as their standard database language.
Why SQL is Important?
- SQL is widely popular and important because of the following reasons:
- SQL allows you to describe and access data in RDBMS.
- SQL allows you to connect with other languages like Java, C, Python through SQL modules, libraries and a different connector.
- SQL allows you to connect with different tables and set permission, procedures, and views.
Different Product of Structure Query Language
The newest version of Oracle, 12c, is designed for the cloud and can be hosted on a single server or multiple servers, and it enables the management of databases holding billions of records.
Microsoft SQL Server 2016, Microsoft made it available on Linux as well as Windows-based platforms. This database engine works on cloud-based servers as well as local servers at the same time.
It is one of the most popular databases for web-based applications and it is open source database. It’s freeware, but it is frequently updated with features and security improvements.
IBM, DB2 is a database engine that has NoSQL capabilities, and it can read JSON and XML files.
SQL Server is Microsoft’s relational database management system (RDBMS). It is a full-featured database primarily designed to compete against competitors Oracle Database (DB) and MySQL. It supports a wide variety of transaction processing, business intelligence and analytics applications in corporate IT environments. It’s one of the three market-leading database technologies, along with Oracle Database and IBM’s DB2.Microsoft SQL Server offers different editions and features to meet a variety of user needs. Some of below editions are:
It is designed for large enterprises and complex data requirements, web-enabled database and data-warehousing. You need to pay a huge amount to get the license.
It is designed to support e-commerce and data warehousing and targeted to medium and small organizations. The license cost is cheaper comparing enterprise edition.
This edition of a database is targeted for small organizations and start-ups. It supports no size and user limits as a backend database for web servers and local uses.
It is free edition provided by Microsoft mainly to replace Access database. Size and number of users are restricted in this edition.
This edition is meant for teasing and application development. It is a single user installation.
This edition is meant for stand-alone applications and it also open source software.
Microsoft SQL Server Business Aspects
Microsoft SQL Server is one the world’s innovative product to meet up business requirements of all the sectors of mid and high-level organizations.
