NHibernate - <natural-id/>(ayende.com)

submitted by adminjew(1490) 2 years, 11 months ago

A natural id is a way to refer to a unique field of an object as a substitute of the real entity identifier. A good (and typical) example of that would be with the User entity. We have the user name and the user id, both are unique, but the user id is usually something that is generated by our application and has no relation to the a human being. In other words, user #123814 doesn’t mean anything to me, while user ‘ayende’ has a meaning to us. read more...

Application structure: Concepts & Features(ayende.com)

submitted by adminjew(1490) 3 years, 2 months ago

I spoke about this topic quite a bit in ALT.Net Seattle. This is mostly relating to application architecture and how you structure your application. This is the logical result of applying the Open Closed and Single Responsibility Principles. Feature may not be as overloaded a term in our industry as a service, but it still important to define exactly what I mean. A feature, in my eyes, is a discrete part of the application that perform some operation. That is pretty vague, I know, but I hope that the examples I am going to go through later would make it clearer. So far, it is pretty much the standard fare, but I have a few rules about a feature, the most important of them is: read more...

Tracking NH Prof performance problem on aggressively active applicatio(ayende.com)

submitted by adminjew(1490) 3 years, 3 months ago

I mentioned before that NH Prof has a problem with dealing with a lot of activity from the profiled application. In essence, until it catch up with what the application is doing, there isn't much that you can do with the profiler. I consider this a bug, and I decided to track that issue with some verifiable results, and not just rely on hunches. The results were... interesting. The actual problem was in the place that I expected it to be, but it was more complex than expected. Let me try to explain. read more...

Patterns, Purists, and Sinkholes(blog.wekeroad.com)

submitted by adminjew(1490) 3 years, 3 months ago

Before I was a geek, I was a Geologist. A Geophysicist to be precise – but mostly I just tell people I was a Geologist. I worked a lot with environmental cleanup, but I also spent a lot of time doing what’s known as “Geotechnical” work – the stuff that happens before buildings are built and holes are dug. It can be kind of boring, but it’s crucially important. One day I was sitting in our lab with some dark Bay Mud in a crucible, slowly adding water in measured doses and then pouring the mud through a screen and weighing out differences. I won’t bore you with the details – I’ll just tell you that I was 23 and cranky that this is what my career amounted to – a bunch of rigorous nonsense where I got to weigh mud. read more...

Cost? (Cost of Messaging)(codebetter.com)

submitted by adminjew(1490) 3 years, 3 months ago

We have come to a very very very important question. What is the cost of Command Query Separation and Messaging in general in comparison to say a more traditional architecture? I would like to look at this from two perspectives. The first perspective is that of the actual cost of using the types of methodologies I bring up. In other words what physical overhead can we see as a result of making the choice? read more...

Discussion: OO 101 Solutions and the Open Close Principle at the archi(ayende.com)

submitted by adminjew(1490) 3 years, 4 months ago

This post is based on the transcript of a conversation between me and Luke Breuer, regarding the application of the Open Close Principle to the system architecture. The quoted sections are Luke's, and my own responses are shown underneath them. This is a different style from my usual posts, because this is a conversation, which was transcriptted and only slighted edited. I hope that this would help all those who wanted to know more about what I meant about using OPC at the architecture level and how to structure systems where you only ever add new things. read more...

Architecture Advice: Scale the architecture to fit the application(ayende.com)

submitted by adminjew(1490) 3 years, 4 months ago

I was just reviewing an application that was obviously built upon a lot of the best practices advice for using an NHibernate application. I am currently in the process of ripping apart much of that application and then putting it back together again. This involve things like collapsing projects, removing abstractions and deleting tests. The main reason for that is quite simple, the architecture is too big for the application. We can create a much more stream lined application is we don't burden it with an architecture that is suitable for bigger and more complex applications. read more...

Building Super-Scalable Web Systems with REST(udidahan.com)

submitted by adminjew(1490) 3 years, 4 months ago

I’ve been consulting with a client who has a wildly successful web-based system, with well over 10 million users and looking at a tenfold growth in the near future. One of the recent features in their system was to show users their local weather and it almost maxed out their capacity. That raised certain warning flags as to the ability of their current architecture to scale to the levels that the business was taking them. read more...
