A relational database management system
A relational database management system is a software that organizes data into tables, columns, and rows, and allows you to manipulate and query data using SQL. SQL is a standard language for accessing and manipulating data in relational databases. With SQL, you can create, read, update, and delete data, as well as perform complex calculations and analysis.
A platform for data-driven applications
Microsoft SQL Server is not only a database system, but also a platform for developing and deploying data-driven applications. It supports various programming languages, such as C#, Java, Python, and R. It also provides tools and services for building web services, business intelligence, and machine learning solutions. For example, you can use SQL Server Reporting Services (SSRS) to create interactive reports and dashboards, or SQL Server Machine Learning Services (ML Services) to run R or Python scripts in the database.
A hybrid data solution
Microsoft SQL Server is a hybrid data solution that allows you to integrate your on-premises and cloud data sources. You can use SQL Server on Azure to run your database in the cloud with built-in security and manageability. You can also use Azure SQL Edge to extend SQL to IoT devices for real-time analysis. Additionally, you can use Azure Synapse Analytics to combine your relational and non-relational data for big data analytics.

Why download Microsoft SQL Server 2018?
Microsoft SQL Server 2018 is the latest version of SQL Server that was released in September 2020. It offers several features and enhancements that make it more powerful, secure, and scalable than previous versions. Here are some of the reasons why you should download Microsoft SQL Server 2018:
The latest features and enhancements
Microsoft SQL Server 2018 introduces many new features and enhancements that improve the performance, security, and functionality of the database system. Some of the notable features are:
Intelligent query processing: This feature optimizes the execution of queries by using adaptive techniques such as batch mode on rowstore, memory grant feedback, table variable deferred compilation, scalar UDF inlining, approximate query processing, etc.
Data virtualization: This feature allows you to query external data sources such as Oracle, MongoDB, Cosmos DB, etc., without importing or copying the data into SQL Server. You can use PolyBase or linked servers to create external tables that reference the external data sources.
Data classification: This feature helps you identify and label sensitive data in your database using metadata tags. You can use the built-in classification engine or customize your own classification rules. You can also use the classification information to monitor and audit your data access.
Always Encrypted with secure enclaves: This feature enhances the security of Always Encrypted by enabling computations on encrypted data using secure enclaves. A secure enclave is a protected region of memory that is isolated from the rest of the system. You can use Always Encrypted with secure enclaves to perform operations such as pattern matching, range comparisons, sorting, etc., on encrypted data.
Accelerated database recovery: This feature improves the availability and performance of the database by reducing the time and resources required for recovery after a failure or a long-running transaction. It uses a new versioning-based engine that maintains the versions of the rows in a persistent version store.
The supported editions and versions
Microsoft SQL Server 2018 supports four main editions: Enterprise, Standard, Developer, and Express. Each edition has different features and capabilities, as well as different licensing and pricing models. You can compare the editions and their features here.
