SQL Server is a relational database management system developed by Microsoft. It includes several editions - Enterprise, Standard, Web, Developer and Express - that differ in features and scale limits. The core components of SQL Server are the Database Engine for data storage and processing, and Analysis Services, Reporting Services, Integration Services, and Master Data Services for analytics, reporting, ETL and master data management respectively. An SQL Server instance is a service that handles application requests to work with databases. It can run on a single computer or across a network. High availability features like log shipping, database mirroring and AlwaysOn are available in higher editions to minimize downtime.

4. SQL Server Editions
SQL Server edition Definition
Enterprise The premium offering, SQL Server Enterprise edition delivers comprehensive high-end datacenter
capabilities with blazing-fast performance, unlimited virtualization
1
, and end-to-end business intelligence
- enabling high service levels for mission-critical workloads and end user access to data insights.
Standard SQL Server Standard edition delivers basic data management and business intelligence database for
departments and small organizations to run their applications and supports common development tools
for on-premises and cloud - enabling effective database management with minimal IT resources.
Web SQL Server Web edition is a low total-cost-of-ownership option for Web hosters and Web VAPs to provide
scalability, affordability, and manageability capabilities for small to large scale Web properties.
Developer SQL Server Developer edition lets developers build any kind of application on top of SQL Server. It includes
all the functionality of Enterprise edition, but is licensed for use as a development and test system, not as
a production server. SQL Server Developer is an ideal choice for people who build and test applications.
Express editions Express edition is the entry-level, free database and is ideal for learning and building desktop and small
server data-driven applications. It is the best choice for independent software vendors, developers, and
hobbyists building client applications. If you need more advanced database features, SQL Server Express
can be seamlessly upgraded to other higher end versions of SQL Server. SQL Server Express LocalDB is a
lightweight version of Express that has all of its programmability features, runs in user mode and has a
fast, zero-configuration installation and a short list of prerequisites.

5. SQL Server Components
Server components Description
SQL Server Database Engine SQL Server Database Engine includes the Database Engine, the core service for storing,
processing, and securing data, replication, full-text search, tools for managing relational and XML
data, in database analytics integration, and PolyBase integration for access to Hadoop and other
heterogeneous data sources, and Machine Learning Services to run Python and R scripts with
relational data.
Analysis Services Analysis Services includes the tools for creating and managing online analytical processing (OLAP)
and data mining applications.
Reporting Services Reporting Services includes server and client components for creating, managing, and deploying
tabular, matrix, graphical, and free-form reports. Reporting Services is also an extensible platform
that you can use to develop report applications.
Integration Services Integration Services is a set of graphical tools and programmable objects for moving, copying, and
transforming data. It also includes the Data Quality Services (DQS) component for Integration
Services.
Master Data Services Master Data Services (MDS) is the SQL Server solution for master data management. MDS can be
configured to manage any domain (products, customers, accounts) and includes hierarchies,
granular security, transactions, data versioning, and business rules, as well as an Add-in for Excel
that can be used to manage data.
Machine Learning Services (In-
Database)
Machine Learning Services (In-Database) supports distributed, scalable machine learning
solutions using enterprise data sources. In SQL Server 2016, the R language was supported. SQL
Server 2019 (15.x) supports R and Python.
Machine Learning Server
(Standalone)
Machine Learning Server (Standalone) supports deployment of distributed, scalable machine
learning solutions on multiple platforms and using multiple enterprise data sources, including
Linux and Hadoop. In SQL Server 2016, the R language was supported. SQL Server 2019 (15.x)
supports R and Python.

8. SQL Server Instance
An instance of the Database Engine operates as a service that handles all application requests to work
with the data in any of the databases managed by that instance. It is the target of the connection requests
(logins) from applications. The connection runs through a network connection if the application and
instance are on separate computers. If the application and instance are on the same computer, the SQL
Server connection can run as either a network connection or an in-memory connection.
