Auf dem API-Portal des Bundes und hier auf GitHub.com/bundesAPI finden Sie Dokumentationen zu Programmierschnittstellen von Verwaltungsleistungen und Informationsportalen des Bundes. Die Dokumentionen liegen idR. im API-Dokumentationsformat OpenAPI 3 vor und sind insofern sowohl menschen- als auch maschinenlesbar.

Momentan finden sich auf bund.dev bereits Dokumentationen zu mehr als 30 Programmierschnittstellen – wobei die Zahl online verfügbarer und dokumentierbarer Schnittstellen aufgrund des „Gesetzes zur Änderung des E-Government-Gesetzes und zur Einführung des Gesetzes für die Nutzung von Daten des öffentlichen Sektors“ (2. Open-Data-Gesetz) bis 2024 stark anwachsen wird.

SourceGrid

SourceGrid is a free open source grid control. Supports virtual grid, custom cells and editors, advanced formatting options and many others features SourceGrid is a Windows Forms control written entirely in C#, goal is to create a simple but flexible grid to use in all of the cases in which it is necessary to visualize or to change a series of data in a table format. There are a lot of controls of this type available, but often are expensive, difficult to be customize or not compatible with .NET. SourceGrid allows users to have customizable datasource which is not in DataSet format.

Trino, the distributed SQL query engine for big data, formerly known as PrestoSQL

https://trino.io

Trino is a highly parallel and distributed query engine, that is built from the ground up for efficient, low latency analytics.

Access data from multiple systems within a single query. For example, join historic log data stored in an S3 object storage with customer data stored in a MySQL relational database.

Do you want to query complex data structures in an iterative way? Do you have access to hierarchical data structures that need to be queried? This course will teach you the tools required to solve these questions. You will learn how to write recursive queries and query hierarchical data structures. To do this, you will use Common Table Expressions (CTE) and the recursion principle on a wide variety of datasets. You will, for example, dig into a flight plan dataset and learn how to find the best and cheapest connection between two airports. After completing this course, you will understand the principle of recursion, and be able to identify and create hierarchical data models.

This article aims at showing good practices on how to retrieve data with SQL using practical examples on the data above. The following topics are covered:

  • operations on columns
  • most common joins
  • aggregations and window functions
  • tips to handle complex queries

Have you ever wondered about the differences between a subquery and a common table expression (CTE) in SQL? The concepts seem very similar, but knowing the difference – and when to use each one – will help you write efficient and readable queries.

MDX Studio

MDX Studio is a tool that was developed by Mosha Pasumansky, a former Analysis Services developer.
This tool is invaluable when writing a MDX query: you have a code formatting feature, an embedded system to analyze query performance and many other features for writing MDX queries.

Unfortunately, the source code is not publicly available and the project is currently no longer being updated by Mosha. Other contributors made an effort to keep the tool compatible with newer versions of Analysis Services and client connection libraries.

The History of Development of Norton Commander

Norton Commander for DOS is the original line of Orthodox file managers that exists in five major versions: 1.0, 2.0, 3.0, 4.0 and 5.0. Only the last one has an additional sub-version (nc 5.5). All versions are still used (mostly by DOS enthusiasts) and are often posted on the abandonware sites. […] It was probably one of the most popular file manager of the DOS era, which along with Xtree remains one of the few programs which managed to transcend their DOS roots and Norton Commander descendants (OFM managers) now exist on all popular OSes. The first version of NC (1.0) was designed and written by John Socha in 1984-1989. We provide a short biographical notes about him later in this chapter.
