In September I will run a masterclass on microservices at Luxoft in Moscow, Russia, see www.luxoft-training.ru/master-class/sander. In preparation of this masterclass, here’s a short Q & A on microservices. Is it worth applying microservices? Q: In your article Microservices. The Good, the Bad, and the Ugly you described different aspects of development. Readers may think that using a microservices architecture […]

Back in 1988, when I was first employed by a company for writing software, the world was fairly simple. The development environment we had was character-based, the database was integrated and traversed with cursors, and we built a whole new administrative system covering everything but the kitchen sink. It took us five years to complete the project, basically because the […]

One of the major items on my wish list – that is on the professional half of it – is to write a book that displays my ideas on software architecture, patterns and frameworks. Yes I know, there are many books on software architecture, and there are many books that explain patterns, and yes there also are a lot of […]

[Session ARC205 at Microsoft TechEd Europe 2010 in Berlin] Use cases have been around for many years describing the requirements of software development projects. From a developer’s point of view, use cases are often seen as too abstract and too complex to develop code from. Until now, that is. During this interactive talk, speaker Sander Hoogendoorn will demonstrate how to […]

To cut to the chase, those of you who have worked on enterprise or service oriented projects before already know this. These types of projects are characterized by a large number of organizational, functional and technically complicating factors. Enterprise software development projects are surrounded by a large number of complicating characteristics and challenges: Many different stakeholders. Projects have many different […]

It’s a mildly sunny April morning in 2002 when I park my car outside of a huge government agency office in a small suburban city near Utrecht. I am invited for a brainstorm session with the agency’s enterprise architects. Although I do not consider myself an enterprise architect, and explained that upfront, they were eager to discuss their architecture with […]

Smart use case stereotypes in service oriented projects

Posted Posted in Documentation, SAP, Service oriented architecture, Smart use cases

Smart use cases are a great technique for specifying standardized requirements in many types of projects. Over the past few years we have smart use cases being modeled and written in projects using Java and .NET, as you might expect, but also in Sharepoint projects, business intelligence, service oriented projects and even SAP implementations. Stereotypes drive standardization Standardization of your […]

In any project, and especially in projects that run under a tight schedule – as most projects do these days, it is helpful to list all elements that can possibly be (re)used to crank up your project, such as guidelines, documentation templates, existing components, (web) services, frameworks. This can best be done early on in the project, traditional or agile. […]

Go to episode three. Go to episode two. Go to episode one. In case you’re wondering why doesn’t this dude come to his point, you’ve probably missed it. I’ve made it already. The point is: you should always have a single point of truth, and at most have it reproduced on the server side. Which in most cases you don’t […]

Go to episode two Go to episode one Client / server could have been a much more successful era in software development, if it wasn’t for this copy-and-paste programming, leading to applications that slowly became unmanageable.
