Web Services are an absolutely horrible choice for data access. It’s a ton of overhead and complexity for almost zero benefit. If your app is going to run on one machine, why deny it the ability to do in-process data access calls? I’m not talking about directly accessing the database from your UI code, I’m … Read more
Biggest advantage is in Localization and Providing alternate resources for different screen sizes. e.g you can have a String resource R.string.myname this could be a defined in english in /values-en/strings.xml and in spanish in /values-es/strings.xml System will take care or picking up the right file depending on the locale you just need to use @string/myname … Read more
Collections are not generally very useful for DAL returns, because a collection does not implicitly guarantee order. It’s just a bucket of items. An IList, on the other hand, does implicitly guarantee order. So we’re down to IEnumerable or IList. The next question would be: is the List object “live”? i.e., is it connected to … Read more

So, now that I’ve vented a little bit, I’d like to address this question(s) because I think that it … Read more
I usually add ClientID to all tables and go with one database. But since the database is usually hard to scale I will also make it possible to run on different database instances for some or all clients. That way you can have a bunch of small clients in one database and the big ones … Read more
So I devised a rather creative solution to my problem… it appears that CMake has no functionality to detect the target architecture whatsoever. Now, we know we can easily do this in C because symbols like __i386__, __x86_64__, etc., will be defined depending on your environment. Fortunately CMake has a try_run function which will compile … Read more
Based on what I understand, a good way to resolve it is by using the OAuth 2 protocol (you can find a little more information about it on http://oauth.net/2/) When your user logs into your application they will get a token and with this token they will be able to send to other services to … Read more
It requires a detailed explanation but I will try to sketch the differences to best of my knowledge. Patterns are distilled commonality that you find in programs. It allows us to deconstruct a large complex structure and build using simple parts. It provides a general solution for a class of problems. A large complex software … Read more
If a framework is opinionated, it lock or guides you into their way of doing things. For example: some people believe that a template system shouldn’t provide access to user defined methods and functions as it leaves the system open to returning raw HTML. So an opinionated framework developer only allows access to data structures. … Read more
