Your Database Table is an awful API

A shared database table can feel like the ultimate shortcut: no API design, no contracts - just a schema. The catch is that this convenience quietly turns into friction: it blurs boundaries, slows change, and makes independent evolution harder than it needs to be. This article looks at why tables (and data-model-shaped “generated APIs”) are such a tempting trap - and what better integration boundaries look like.

A Brief History of HTTP

Common Approaches in the Field of Socio-Technical Architectures

In the age of digitalization and modernization, companies face the challenge of not only keeping up with technological advancements but also optimizing their organizational structures. Socio-technical architectures play a crucial role in this process by focusing on the flow of work, team collaboration, and the seamless integration of technical and social systems. This article explores two key approaches—Team Topologies and Domain-Driven Design (DDD)—and demonstrates how they can help organizations take the first steps toward consciously designing their socio-technical architecture.

gRPC

One of the main tasks that business sets for IT as an industry is the creation of effective software, according to criteria that clearly meet the needs of this business. On the other side, one of the main prerequisites for achieving the goals that a business sets for itself is the ability to hire specialists who can create a product in the shortest possible time and/or effectively maintain it. Accordingly, to achieve this, the technology stack used, i.e. tools, must be mature enough, and widely used in the market.

Declarative HTTP API Testing with gabbi

While HTTP APIs are ubiquitous these days, testing and documenting such APIs remains somewhat awkward: Tests usually consist of procedural code that is specific to the respective language or even framework - which is neither very expressive nor easy to maintain.
