How to combine data from several sources using SQL and VirtualQuery

Posted by on July 28th, 2016

The VirtualQuery component allows to perform SQL queries to sources, that are not a database, but a TDataSet or any its descendant. It also allows to connect to several data sources at a time and work with them using SQL queries as with a single data source. Thus, work in heterogeneous environment is implemented, when execution results of queries to different sources can be retrieved in a single data set.

SQL Server 2016 Stretch Database

Posted by on July 12th, 2016

SQL Server 2016 Stretch Database

On June 1, SQL Server 2016 was released. It brought a large number of novelties into normal development, including the long-announced Stretch Database technology that allows migrating data from SQL Server dynamically to Azure.

From the marketing point of view, Stretch Database has been well promoted. Reasonable arguments were stating that with the growth of historical data the complexity and cost of its maintenance grows as well. As a rational solution to the problem, the automatic migration of obsolescent archival data to the cloud was introduced. Frankly speaking, I enjoyed the idea.

As from SQL Server 2016 RC0, I began testing the Stretch Database technology on two projects I’m helping to develop. The first one is TMetric, a free time tracker with OLTP load, and the second one is an internal project with DW load.

Migrating Entity Framework 6 projects to Entity Framework Core 1 (Entity Framework 7)

Posted by on April 25th, 2016

For the purpose of this tutorial, we will use a test project from the “Entity Framework 6 Support for Oracle, MySQL, PostgreSQL, SQLite, DB2, and Salesforce” blog article. We will update this project so that it could be used with Entity Framework Core 1 (Entity Framework 7).

This is not a full-featured tutorial that completely describes migration of Entity Framework 6 projects to Entity Framework Core (Entity Framework 7). We will describe only several of the possible problems and solutions, which we found when migrating a simple and small project that uses only a small part of Entity Framework 6 features.

As one expects, migration from Entity Framework 6 to Entity Framework Core should have been just the following simple steps:

  • change Target Framework for projects;
  • delete old NuGet package
  • add new NuGet package
  • make some configuration changes (though one can expect some vertical compatibility between different versions of the same ORM, and consider this step unnecessary).

That should have been all the steps. However, in reality there are much more problems than one should expect. And in this article we will describe some of these problems and their solutions.
