It provides a number of classes that abstract and encapsulate database-related operations. It associates the data in the database table with an XML file, which means that it allows the data to be converted between the XML file and the database. Based on this design pattern Dbunit can back up the database into a temporary XML

So for streaming I think it's also necessary to have a similar SQL query language. The current streaming platform framework like storm forces the user to implement some of the query pattern operations like silding window

Container classificationFrom the point of view of business data, containers can be divided into two categories: stateless (stateless) containers and stateful (stateful) containers.Stateless means that the container does not need to save data while it is running, and the result of each access does not depend on the last access, such as a Web server that provides a static page.Stateful means that the container needs to save the data, and the data changes, and the results of the access depend on th

Below the query, I instantiate a streaminsight "server" to host the query and define a streaminsight application to include the query. Next, I converted the odata results into a CEP stream and created a streaminsight query using the tumbling window to output the number of employees in each country in each of the 60 skylights, finally, output the result to linqpad.

Streaminsight is a new module in SQL Server 2008 R2. It provides the complex event processing (CEP, complex event processing) function. That is, it provides nearly zero-latency continuous processing for infinite event sequences from multiple data sources. Streaminsight is a temporary query processing engine that allows applications to query and process events within a time win
