A high-quality RDBMS

Microsoft SQL Server 2019 is a relational database management system (RDBMS) developed by Microsoft Corporation. Transact-SQL is the primary query language created jointly by Microsoft and Sybase. Transact-SQL implements the ANSI/ISO standard on Structured Query Language (SQL) with extensions.

It works with databases ranging in size from personal to large enterprise-wide databases. It also competes with other DBMSs in this market segment. This software is available for Windows, so that we will tell you more about it.

What is this program?

SQL Server 2019 Express Edition is a mission-critical enterprise platform with high availability, enhanced performance, and security. This solution is a highly scalable, completely relational, and rapid server that processes large amounts of data for client-server applications.

New technologies provide record performance of MS SQL Server for working with memory to help enterprises accelerate their businesses and realize new work scenarios. Moreover, SQL Server enables new hybrid cloud solutions and benefits of cloud computing.

Advanced security features, combined with built-in and easy-to-use tools and managed data access, allow organizations to meet strict compliance policies.

What is working with databases used for?

The notion of a database may differ depending on the viewpoint: a user or a system. In the first case, the database is a table with the necessary data (information) displayed on a monitor or even a piece of paper. In the second case, the database is a set of files where tables and links between them are implemented. Access from users should be organized for them.

Today, this access is organized centrally. The server and client interaction is the basis of modern technology. Clients are users' personal computers, and database servers are robust, high-performance computers that provide simultaneous access to data from hundreds and thousands of users.

The server provides data, and the clients request it by sending an SQL query to the server by the client. The server processes the request, returning the requested data to the client. Since the query is implemented in the unique SQL language, it is transparent both for the server and the user.

What tasks does this software solve?

Being a DBMS, SQL Server 2019 Express Edition for Windows solves the following tasks:

  • Retrieving data from disk and saving data to disk;

  • Working with data in the RAM server;

  • Logging (journaling and logging the database alteration history);

  • Support user queries to define and manipulate data in the structured SQL language.

Primary features of the software

  • SQL Server 2019 allows you to dynamically encrypt the complete database, all data files, and log files. At the same time, there are no changes to existing applications;

  • Improved data mirroring and support for automatic recovery of any data pages;

  • SQL Server 2019 provides outbound log stream compression, allowing you to achieve optimal mirroring performance while minimizing network load;

  • A resource controller will enable you to achieve stable and predictable response times for end-user requests;

  • SQL Server 2019 provides policy-based management, allowing you to manage one or more existing SQL Server 2019 instances easily;

  • New valuable features include conversion, logical, analytical, string, and by-time (date and time) functions.

Easy handling of large databases

SQL Server 2019 makes it easy to deploy, transfer, and integrate big data through the following aspects:

  • The Kubernetes-based big data solution built into SQL Server makes it easy to deploy and work with a big data cluster. Kubernetes provides deployment of HDFS storage, SQL Server relational module, and Spark analytics tools as containers in one convenient package;

  • SQL Server 2019 includes Spark and HDFS, allowing you to read and write directly to HDFS using SQL Server or Spark. Kubernetes architecture provides flexible scaling of computing and storage capacity on demand.

Integrating structured and unstructured data

Modern data volumes make it unreasonable and unprofitable to convert all available data into relational tables for storage in a DBMS. Earlier, Microsoft introduced PolyBase technology that allows a SQL Server instance to handle Transact-SQL queries that access Hadoop data and merge data from Hadoop and SQL Server.

In SQL Server, an external table or data source provides a connection to Hadoop, virtualizing external data sources without importing them into the relational database directly and then allowing you to query that data.

This way, data is accumulated in raw format but can be represented as a virtual table. Virtualization allows you to integrate data of different formats from heterogeneous sources and storage locations without replication and relocation, creating a single virtual data matrix.

High performance

This is not the first year that Microsoft has validated the high performance of SQL Server with transactional and data warehouse performance tests. Excellent results in the following tests mark the 2019 version:

  • OLTP performance;

  • DW performance for 1TB, 10TB, and 30TB;

  • OLTP price-to-performance ratio;

  • DW price-to-performance ratio for 1TB, 10TB, and 30TB.

Persistent memory support (PMEM)

Persistent Memory (PMEM) is a fast memory that can store data after power failure. It enables in-memory processing, eliminating the need to transfer data across transmission links and speeding up query processing by 30% for I/O-intensive workloads.

Any SQL Server file placed on the PMM appliance is now directly accessible, bypassing the operating system storage stack, using efficient memory operations.

Security and compliance

Sensitive data is protected with Always Encrypted technology with secure enclaves. In-place encryption allows you to perform cryptographic operations on sensitive data without moving it outside the database.

Cryptographic operations include column encryption, which can now be performed with Transact-SQL. They do not require moving the data out of the database. All full-featured calculations are supported within protected enclaves, including range matching and comparisons, greatly extending their applicability.

Always Encrypted technology with protected enclaves is available in Windows Server 2019.

Intelligent data analysis

The development of SQL Server has gone the way of integration with other analytical platforms and Spark in particular, which is now included in the transfer of SQL Server.

Spark is a viral tool for machine learning and advanced analytics. It has an efficient in-memory machine. All this is integrated with SQL, which effectively visualizes analytics.

Proper analysis and effective presentation of the results directly affect the effectiveness of data analysis and the ability to make management decisions based on it.
