Transactions are an integral part of any (serious) database development when there is need for data consistency. Transactions in a database environment have two main purposes: To provide reliable mechanism to allow correct recovery from failures and keep a database consistent To provide isolation between programs accessing a database concurrently. It’s impossible to mention transactions without mentioning the ACID (Atomic, Consistent, Isolated and Durable) attributes [… read more]

The following is a list of books that I would recommend to every experienced (or not) software developer. Very often I take inspiration by reading again and again some chapters as very often the knowledge (theory), if not practiced, tends to blurry overtime. Please take the list as it is without any order of precedence. Every book is important for its own topic. Patterns of [… read more]

We mention Cohesion and Coupling when we are talking about Software Design Principles. Those two principles were first introduced in the book Structured Design: Fundamentals of a discipline of computer program and system design many years ago, even though the principles were around Structured Programming, they are still valid in the Object Oriented world. Cohesion Cohesion represents the degree of the systematic or logical connection [… read more]

Here is the problem: How to properly display a user-friendly error message for an exception being thrown from an ASP.NET Web Service? I know that we shouldn’t be really working anymore with ASP.NET Web Services as a huge amount of problems have been solved with the WCF framework. But, for those like me, that are working on some large-scale projects where we are still using [… read more]

This is my first post about the code refactoring, and I hope that in the future there will be many, as I find this topic particularly important and interesting. I would like to start with one very simple method but perhaps not so often used in the real life programming: Composed Method pattern. One way of refactoring the code, or in our case a method, [… read more]
