Recently, the NoSQL database is gaining more and more popularity. They differ favourably from conventional relational databases and provide the following: high resilience, incredibly large amounts of data, good scalability, clustering. One of the new NoSQL databases is RavenDB. This is a document-oriented database, like the popular MongoDB. But compared to the last, RavenDB is an open source database. This means you can use it in your apps for free and add functionality according to your wish.
NosDB is a prominent representative of the NoSQL databases. It is designed for use on the .Net platform and has open source. NosDb, like many other non-relational databases, has a high speed and good linear scalability. In this article, we'll look at the way to connect to the NosDb database inside the report with a plug-in for the designer. As you know, you can connect plug-ins to a report designer that expands the functionality of the program. One of the areas of expansion of functionality is connectors to different databases. Indeed, it takes a lot of time to find, install and set connectors for different databases. FastReport allows you to create plugins that make the process of connecting to data as much easier as possible.
With this Easter egg, FastReport developers decided to show us an alternative way to use their generator. Based on the report, they created a game - the well-known Minesweeper. Surprisingly, this is indeed possible thanks to the built-in report script!
Data analysis requires reports with a drop-down list. Using data grouping, but with the ability to hide or display data by mouse click. This is not only very convenient, but also beautiful.
The essence of a Master-Detail report is a one-to-many relationship between data entities. That is, one record in the main table corresponds to several in the subordinate table.
