What is a (business) process, actually?

Leider ist der Eintrag nur auf English verfügbar.The terms process and business process, in particular, are sometimes used lightly and without thinking too much about what those terms actually mean. Drawing upon and thinking in terms of the concept of a value chain (i.e., a set of activities designed to create a product or service that has value to a customer) some time ago I came up with this definition of what constitutes a process, not just when it comes to business ...

Leider ist der Eintrag nur auf English verfügbar.Two of the most popular posts on this blog cover resources for Spring Batch and how to use Maven Failsafe with Spring Boot: Spring Batch Resources: Batch Processing, ETL And Data Conversion Using Maven Failsafe With Spring Boot While doing some regular blog housekeeping, I recently revised those articles and fixed a few broken links. If you're interested in these technologies and frameworks, you might want to check those articles out.

Inversion of Control vs Dependency Injection

Leider ist der Eintrag nur auf English verfügbar.Dependency injection is one way of implementing inversion of control - a programming principle that allows for better modularity and extensibility. Dependency injection is commonly achieved via constructor injection, field injection, or setter injection. Inversion of control is an abstract concept, which dependency injection is a realisation of. Other methods of implementing inversion of control for example include the template pattern, service discovery, delegates, events, and currying (when applying a functional programming paradigm).

Currying in JavaScript

Leider ist der Eintrag nur auf English verfügbar.A reference to logician Haskell Curry, currying is a technique for converting a function that takes multiple arguments into a chain of abstract functions that each take a single argument (see Currying). Besides its significance for studying functions in the context of theoretical computer science and its relevance to lambda calculus both in the context of mathematics and linguistics, currying has very practical applications in functional programming. In a way, it's one possible approach for following ...

Using SQLite on a Static Website Without a Back-end Server

Leider ist der Eintrag nur auf English verfügbar.GitHub user phiresky recently published an interesting blog post on Hosting SQLite databases on Github Pages. Using SQLite - or in fact any kind of SQL database - in the browser? Why should one want to do this? Now, while it's certainly true that in the context of web applications SQL databases and RDBMS generally are relegated to the realm of back-end servers, depending on the requirements, a database in a front-end application or a ...

Hexagonal Architectures: @Column(nullable = false) vs @NotNull in Java Applications

Leider ist der Eintrag nur auf English verfügbar.Recently, I came across a small and common, but all the more interesting, hands-on example of why a hexagonal architecture can help with making both the architecture and the code of an application more understandable, approachable, and maintainable. I won't be going into any details about the concept of and ideas behind hexagonal architecture here. The gist is summarised quite nicely in this quote from Tom Homberg's article on Hexagonal Architecture with Java and Spring: The ...

A few random thoughts on the development of software development in recent years

Leider ist der Eintrag nur auf English verfügbar.Last year, I replied to Tom's question "Has software development grown harder over the last years or have I just grown sluggish?" on Twitter with these incoherent ramblings of a greybeard, who has seen at least 3 fat-client-thin-client cycles: As usual it depends. Just a few examples: Spring Webflux and the "Everything has to be reactive even if the requirements don't demand it." fad is a bane. Just recently, I've been helping a client with getting ...
