Part one of a two Part Series
Microsoft SQL Server is a relational database management system (RDBMS) developed by Microsoft. It is a software product with the primary function of storing and retrieving data as requested by other software applications. The SQL Server may run on the same computer or another computer across a network (including the Internet). Microsoft SQL Server is supported by Windows, Linux, and Docker containers.
SQL Server is available in several editions, with different feature sets and pricing.
SQL Server web edition is a low-cost, easy-to-use relational database management system (RDBMS) designed for web hosting. It supports all the features of the SQL Server Express edition, including the ability to host multiple databases.
SQL Server Developer edition includes all the features of the SQL Server web edition, plus additional tools and features that make it ideal for developing and testing applications.
SQL Server Express Edition is a free, entry-level RDBMS for small-scale applications. It has several limitations compared to the other editions, but it is still a fully functional database management system.
SQL Server Standard edition includes all the features of the SQL Server Express edition, plus many more advanced features such as online indexing and partitioning.
SQL Server Enterprise Edition includes all the features of the standard edition, plus even more advanced features such as data compression and auditing.
Cloud-based versions of SQL Server are also available, which can be hosted on Azure, Amazon Web Services (AWS), or Google Cloud Platform (GCP). These versions offer the same features as the on-premises versions but with the added benefit of being more scalable and easier to manage.
Microsoft SQL Server has been around since the early 1990s and is a widely used database system. It is known for its reliability, ease of use, and performance. In recent years, Microsoft has made many improvements to SQL Server, such as adding support for big data and cloud computing.
If you're considering using SQL Server in your organization, you should know a few things. In this article, we'll discuss some of the key features of SQL Server and its pros and cons.
Relational Database Management System
A relational database management system (RDBMS) is a computer program that enables you to store, modify, and query data in a relational database. An RDBMS typically uses a server to store the data, with clients accessing the data through various front-end applications. The client applications may be web-based, desktop-based, or mobile-based.
The most popular RDBMSs are MySQL, Oracle Database, Microsoft SQL Server, and IBM DB2. Other less popular RDBMSs include Sybase ASE, PostgreSQL, and Microsoft Access.
When you create a new database using an RDBMS, you must first define its structure by creating tables and fields. Tables are the basic structure of a relational database, and fields are the specific attributes of a table. For example, you might create a table for customers that contains the following fields: customer ID, name, address, phone number, and email address.
Once you have created the tables and fields, you can add data to the database using various SQL commands, such as INSERT, UPDATE, and DELETE. These commands enable you to add, modify, and delete data in the database.
To query the data in a database, you must specify which columns of data you want to retrieve from the database.
The SQL language is a standard that all major RDBMSs support. However, each RDBMS has its own proprietary extensions to SQL that enable you to take advantage of specific features of that RDBMS. For example, Microsoft SQL Server provides extensions allowing you to store and retrieve data using the Transact-SQL language in a Microsoft SQL Server database.
When choosing an RDBMS, you should consider which features are important to you and how well each RDBMS supports those features. Some of the most important features to consider include the following:
- Ease of use
- Support for standard SQL
- Support for proprietary extensions
- Cost
- Platform support
- Scalability
- Security
- Backup and recovery

SQL Server with client/server applications
If you're using a client/server application, you'll need to use SQL Server. This type of application uses a server to store data and an application to access that data. The application can run on any number of computers, but the data is stored centrally on the server.
SQL Server is a powerful database server that can handle large amounts of data. It's also easy to use, making it a good choice for businesses that want to keep their data in one place.
There are two ways to use SQL Server with client/server applications:
- Use the Microsoft SQL Server Driver for PHP to connect to SQL Server from your PHP scripts.
- Use the Microsoft SQL Server Driver for ODBC to connect to SQL Server from your ODBC-compatible application.
The Microsoft SQL Server Driver for PHP is a free, open-source library that makes it easy to access SQL Server data from PHP scripts. The driver includes several features that make it easy to work with SQL Server, including:
- Support for all major SQL Server data types.
- Support for transactions.
- Ability to connect to multiple SQL Server databases simultaneously.
- Easy installation and configuration.
The Microsoft SQL Server Driver for ODBC is a free, open-source library that makes it easy to access SQL Server data from ODBC-compatible applications. The driver includes several features that make it easy to work with SQL Server, including:
- Support for all major SQL Server data types.
- Support for transactions.
- Ability to connect to multiple SQL Server databases simultaneously.
- Easy installation and configuration.
Using Microsoft SQL Server to run Internet Information Services (IIS)
Microsoft SQL Server can be used to run Internet Information Services (IIS). IIS is a web server that provides a platform for hosting web applications and services. By using Microsoft SQL Server to run IIS, you can take advantage of its scalability, performance, and security features.
To use Microsoft SQL Server to run IIS, you need to install the Web Server role on a computer running Microsoft SQL Server. The Web Server role includes the necessary components for running IIS, such as the World Wide Web Publishing Service (WWW service) and the ASP.NET framework.
Once you have installed the Web Server role, you can configure IIS to use Microsoft SQL Server. To do this, you need to edit the configuration settings for IIS. You can access the IIS configuration settings by opening the IIS Manager tool.
In the IIS Manager tool, select the server you want to configure. Then, in the left pane, expand the tree view and select the "Sites" node. Under the "Sites" node, choose the site you want to configure.
In the right pane, double-click on the " ASP.NET " icon. This will open the ASP.NET Settings dialog box. In the ASP.NET Settings dialog box, select the " Use Native Image Generator " checkbox. This will enable IIS to use Microsoft SQL Server to generate native images for ASP.NET applications.
Click OK to close the dialog box. You will now need to restart IIS for the changes to take effect. To do this, open the Command Prompt tool and type the following command:
iisreset /restart
Once IIS has been restarted, you can test it using Microsoft SQL Server by accessing an ASP.NET application hosted on the server. If you see the " ASP.NET " icon in the page header, then IIS is using Microsoft SQL Server to generate the page.
Relational Database Management System scalability and performance
Microsoft SQL Server 2019 is a powerful relational database management system (RDBMS) that offers scalability and performance for mission-critical workloads. With its In-Memory OLTP engine, SQL Server 2019 can power real-time operational analytics and deliver up to 30x performance gains over traditional disk-based systems.

And with Always On Availability Groups, SQL Server 2019 provides enhanced resilience and availability for your most critical databases.
If you're looking for a powerful RDBMS that can scale to meet the demanding needs of your organization, look no further than Microsoft SQL Server 2019.
Relational Database Management Systems high availability
Microsoft SQL Server 2019 provides high availability for relational database management systems (RDBMS) through various features and tools. For example, high availability can be achieved through failover clustering, Always On Availability Groups, log shipping, and database mirroring.
Always On Availability Groups provide high availability and disaster recovery for databases without needing a failover cluster. Always On Availability Groups protect databases from data loss and corruption and allow for fast failover during an outage or disaster. In addition, Always On Availability Groups can be used to improve performance by allowing read-only access to secondary databases.
Failover clustering provides essential high availability for SQL Server databases. Failover clustering protects against server outages and allows for automatic failover to a standby server during an outage. Failover clustering requires a shared storage solution, such as SAN, and can be complex to configure and manage.
Log shipping is a basic high-availability solution that copies transaction logs from a primary database to a secondary database. Log shipping can be used to improve performance by allowing read-only access to the secondary database. However, Log shipping does not protect against data loss and can be complex to configure and manage.
Database mirroring is a high-availability solution that copies data from a primary database to a secondary database. Database mirroring can improve performance by allowing read-only access to the secondary database. However, Database mirroring does not protect against data loss and can be complex to configure and manage.
