But there is still a long way to go. First, let’s try to define what a subdomain is. Every business operates in some business domain – we all know that.

Years ago I wanted to start learning Domain-Driven Design. It was quite a popular topic, many of my colleagues were discussing it. The problem, as always, was where to start. I decided to ask one of my old mentors. He told me, “MJ, there is a great book about DDD called the Blue Book. Go and read it and everything will be clear. There is nothing better on the market”. “Well, it m...

In recent years, I have encountered many problems in IT companies caused by incorrect software architecture. What do I mean ?

Recent years have been marked by microservices. Who among you hasn’t heard of them? They were everywhere – at conferences, groups, job listings, coffee talks, and blog posts.

Recently, I had the pleasure of speaking at 2 programming events – World Engineering Days and one of the biggest software conferences in Poland, 4Developers. During both speeches, I talked about many different things related to the modern way of software development – continuous deployments, short-living branches, canary releases, and more. All are linked to the short feedback cycle. One of the side topics was vertical slices. What is a vertical slice? Before we ...

~ MJIQueryable W przypadku IQueryable, wszystkie wyniki najpierw odfiltrowujemy po stronie bazy danych, a następnie przekazujemy do aplikacji.IEnumerable W przypadku IEnumerable, wszystkie wyniki z bazy danych najpierw ładujemy do pamięci, a następnie odfiltrowujemy po stronie aplikacji. W przypadku zapytań do bazy danych, dużo lepszym pomysłem będzie stosowanie IQueryable, ponieważ można skorzystać z dobrodziejstw SQL, co znacznie przyspieszy szybkość działania zapytania oraz zmniejszy ruch wewną...
