API: Arrays or named elements?

The humble restaurant menu follows a common pattern where menu items are generally separated into a logical hierarchy. At the top level, we may have breakfast items, dinner items or drinks items. Each of these could be grouped further into categories like meat dishes, fish dishes or pasta dishes (dinner items), and again into burgers and steaks (m...

DDD: what aisle is your attribute in?

During a Domain Driven Design (DDD) workshop this week, one of my colleagues very cleverly used grocery store aisles as an analogy to explain why attributes should be grouped into entities. He explained that grocery stores group logical produce together to make it easier for customers to find what they are looking for. Thereby suggesting that gro

Fireworks or APIs - 'meh'

Every New Year’s Eve we are wowed by extravagant fireworks from around the world - we anticipate them and we expect them. This New Year’s Eve was no different, except for me – this year I was in Copenhagen city center; on the balcony of a friend’s apartment, watching. In Denmark, anyone, over a certain age, can purchase and set off fireworks duri

Nouns and Verbs in the world of APIs

Please note that this is a little more technical than my previous articles – sometimes I need to let my inner-geek out. Simply because RESTful APIs are based on resources and use the HTTP verbs (GET, POST, PUT, DELETE, PATCH), does not mean they should only support CRUD (Create, Read, Update, Delete) operations. RESTful APIs can also be used for ...

Turkey Talk and APIs

A good friend of mine was out walking his dog in the countryside the other day. After a while, his dog noticed some turkeys in the adjacent field, and being a dog, decided to investigate. This involved some barking and general running up and down along the fence. I suppose, in the dog’s mind, he was telling the turkeys that he was defending his m

APIs and the Abstraction of Cars

In 2010, for the first time in history, we registered over a billion passenger cars on our roads, globally. It is estimated that by 2050, there will be 2.5 billion cars on our roads! Clearly, cars are a big part of our lives and will continue to stay for a while. That being said, have you ever opened the bonnet of your car and had a look inside t

API Security: Who has the right key?

Everyone has at least one set of keys; don’t they? You can recognize your keys and you make sure you take them wherever you go. Look at each key on your keyring and you know which door or cabinet it opens (well, we should know anyway). Some of us have keys we no longer know the purpose of – what we do know is that the lock for that key is probabl

Apitalism: 3 Deadly Sins to Avoid When Developing and Using Banking APIs

Warren Buffett is a smart role model for many people, including me. Although closely monitoring his insights and steps did not help me to create a fraction of wealth he has; I still cannot deny the fact that there are fantastic ideas and insights I learned from his shares. Once he said "After 25 years of buying and supervising a great variety...

API Orchestration or Choreography, what’s your choice?

Have you’ve ever visited India? How did you cope with the traffic there? It’s clearly different to the regular, organized approach we are used to in Europe. After spending a couple of days in Bangalore recently, I became aware that my reaction to traffic had changed; I was not fazed (read terrified) by traffic behavior anymore and actually started

Should APIs be Pre-made or Deli style?

I was out looking for a sandwich for lunch the other day and found myself faced by two options; I could either go to the convenience store and pick up a pre-made sandwich or go to the deli and have one made for me. The pre-made option sounds simple, but choice is usually limited to the imagination of the sandwich maker. Going to a deli to have a s
