Introduction

Microsoft SQL Server is a service that runs on operating systems. A service is a type of application that runs in the system's background. Services typically provide core operating system features like Web serving, event logging, and file serving. Services can run without displaying a graphical user interface on the computer's desktop. 

As services, the SQL Server Database Engine, SQL Server Agent, and several other SQL Server components operate. These services are typically launched when the operating system boots. The settings determine this; some services are not enabled by default.

This article discusses SQL Server services. Before you can log in to a SQL Server instance, you must first understand how to start, stop, pause, resume, and restart it. After you've logged in, you can do things like administering the server or query a database.

SQL Services

MS SQL Server provides the two services listed below, which are required for database creation and maintenance. Other add-on services for various purposes are also listed.

Three types of services: Microsoft SQL ServerSQL Server AgentFive type of add on services

The mandatory services are:

  • SQL Server

Start, Pause, Resume, Stop, or Restart an Instance of the SQL Server Database Engine

  • Start SQL Server Configuration Manager by following the steps outlined above.
  • Select Yes if the User Account Control dialogue box appears.
  • Select SQL Server Services from the left pane of SQL Server Configuration Manager.
  • Right-click SQL Server (MSSQLServer) or a named instance in the results pane, and then choose Start, Stop, Pause, Resume, or Restart.
  • To close the SQL Server Configuration Manager, click OK.

Database Engine

It is a default server type. It is used to store, manage, and access the data from the Database.

The Database Engine is the heart of the SQL Server. The Database Engine is made up of two components: a relational engine that processes queries and a storage engine that manages database files, pages, indexes, and so on. The Database Engine also creates and executes database objects such as stored procedures, views, and triggers.

Relational Engine

The components that determine the best way to execute a query are found in the Relational Engine. Another name for query processors is the relational engine.

Based on the input query, the relational engine requests data from the storage engine and processes the results.

The relational engine performs tasks such as query processing, memory management, thread and task management, buffer management, and distributed query processing.

Storage Engine

The storage engine manages data storage and retrieval from storage systems such as discs and SAN.

Analysis Services

Analysis Services is a decision support and business analytics analytical data engine (VertiPaq). It offers enterprise-level semantic data models for business reports and client applications like Power BI, Excel, Reporting Services reports, and other data visualisation tools.

SQL Server Analysis Services, when installed as an on-premises server instance, supports tabular models at all compatibility levels (depending on the version), multidimensional models, data mining, and Power Pivot for SharePoint.

Analysis Services Workflow

A typical implementation workflow includes installing a SQL Server Analysis Services instance, creating a tabular or multidimensional data model, deploying the model as a database to a server instance, processing the database to load it with data, and then assigning permissions to allow data access. When complete, the data model can be accessed by any client application that supports Analysis Services as a data source.

To create a model, open Visual Studio and select a Tabular or Multidimensional project template from the Analysis Services projects extension, also known as SQL Server Data Tools or simply SSDT. The project template includes folders for all of the model's objects. All the basic elements, such as data sources, data source views, cubes, dimensions,  and roles, can be created using wizards. Visual Studio and DevOps enable effective CI/CD pipelines.

Data from external data systems, typically data warehouses hosted on a SQL Server or Oracle relational database engine, is used to populate models (Tabular models support additional data source types).

To use a model, it must be deployed to a server instance that runs databases in a specific server mode, making the data accessible to authorised users via Excel or other applications.

Reporting Services

For reporting services, we use SQL Server Reporting Services or SSRS. SQL Server Reporting Services is a reporting application that lets you create formatted reports with tables in the form of data, graphs, images, and charts. These reports are stored on a server and can be run at any time using user-defined parameters. It is a component of the Microsoft SQL Server Services suite.

Reporting Services is a reporting tool used to generate reports in various formats.

These formats are

  • Standard: It is used to display the report in the List format.
  • AD-Hoc: It is used to create the report template or the Report model, and when the client uses it, the necessary changes are made.
  • Embedded: The reports will be delivered to the development team, who will integrate them into the DotNet Project.
     

Must Read SQL Clauses

Compact Edition

Microsoft SQL Server Compact 4.0 is a free embedded database that can be used by software developers to create ASP.NET websites and Windows desktop applications. SQL Server Compact 4.0 has a small footprint and allows for private deployment of binaries within the application folder, easy application development in Visual Studio and WebMatrix, and seamless schema and data migration to SQL Server.

Integration Services

The integration services in Microsoft services are done using SQL Server Integration Services. SQL Server Integration Services, also known as SSIS, is a component of the Microsoft SQL Server database software used to perform various integration tasks. It is a data warehouse tool used for data extraction, loading data into another database, cleaning, aggregating, merging data, and so on.

SSIS also includes graphical tools and window wizards for workflow functions like sending email messages, FTP operations, and data sources. SSIS is used for a variety of transformation and integration tasks. The SSIS tool is used in data migration as a whole.

Its purpose is to convert data from one format to another. We can convert SQL Server tables to Oracle, MYSQL, or MS Access tables, and we can also convert "table" to "textfile" or "textfile" to "table." This allows for 27 transformations. The ETL (Extract Transform Load) Tool is what it's called. 

SSIS Uses

SSIS is primarily used to perform two specific functionalities:

Data Integration: SSIS performs data integration by combining data from multiple sources and providing users with unified data.

Workflow: Workflow can be used for a variety of tasks. Sometimes we need to execute specific steps or take a particular path based on time. A parameter is passed to the package or data queried from the database. It can be used to automate SQL Server database maintenance and to update multidimensional analytical data.
