Do you want a Database Management System which can run on-premises, on-cloud or on-Azure stack? Microsoft SQL Server 2019 is exactly for you. The new SQL Server 2019 gives users the manageability of big data clusters, enhanced security and easy integration with other tools.
Microsoft has announced the availability of Microsoft Sql server 2019. This preview has been build on previous versions which gives you choice of developmental languages and Operating Systems. The new DB Server comes with features like enable the query of other databases like Oracle, Teradata and MongoDB directly from SQL Server. You will see a lot of new features in this version.
The latest version simplifies big data analytics for SQL Server users. The new SQL server combines HDFS (the Hadoop Distributed Filing System) and Apache Spark and provides one integrated system. It provides the facility of data virtualization by integrating data without extracting , transforming and loading it. Big data clusters are difficult to deploy but if you have Kubernetes infrastructure, a single command will deploy your big data cluster in about half an hour.
Master Data Services (MDS)
The Silverlight support of Master Data Services is no longer required. HTML controls will now perform the same functionality.
Advanced security support has been provided in the new version. It encrypts the data using secure enclaves technology. Similarly support for security certificates has also been provided and only only user with administrative role can alter the database.
A new cloud based architecture has been introduced called SQL Database Hyperscale. It provides about !00 TB data storage. You can scale up and down you database. There are primary as well as secondary instances which perform the function accordingly and reduce the workload like in case of log service the primary instance writes the log to the log service and secondary instance consume the log service.
Oracle, Teradata, MongoDB
The PolyBase product which was in earlier version too has been expanded. Sql server can now support quieries from external sources like Oracle, Teradata, MongoDB which as a result increases the flexibility of the sql server
Azure Data Studio for SQL Server
Azure data studio allows you to quickly visualize your data based on its built in features. It is a modern development environment which helps you with data development and integration tasks.
SQL Server Management Studio has also recently been released which provide support for sql server 2019. It has been ported to Visual Studio 2017 isolated shell. Some bug fixes like backup, restore, attach has been introduced wile some features has been deprecated like Database Diagram, TSQL Debugger, OSQL.exe, Dreplay Admin UI, Configuration Manager tools, SQL Server Configuration and Reporting Server Configuration Manager
The additional security brings some limitation s with it. You cannot perform any mathematical operation on the encrypted data.Query will only be accepted if it has the equality values like “where 1=1”.
Cost Competitive Migration
With some additional features come huge cost. Deploying existing workloads on new one is not an easy task. A practical solution for cost competitive migration needs to be provided for migration from old version to new one.
