If yes, how? I can go one step further and say that globalization is a kind of feature we should consider the use of a "framework" or a "service" (or even both, depending on some kind of configuration). "You call a library, a framework calls you", Re: "You call a library, a framework calls you", You write that you would select XNA for Game development. The users will then be able to depend only on the common assembly and thanks to an IoC container choose which "family" to use at run-time. If we decide it will be C# but not XNA, will it be Windows Forms? With this extra "layer" you will be able to replace the creation of a service from a specific library to a "generic" one, and so you will be able to replace the implementation at any moment (including a local service instead of a remote one) without breaking all the places that instantiate the service. Will we use Javascript? Simon is an independent consultant specializing in software architecture, and the author of Software Architecture for Developers (a developer-friendly guide to software architecture, technical leadership and the balance with agility). You can replace the entire SQL Server family by the entire Oracle family, but you can't replace only the connection without replacing the other components. This usually requires hands-on work in terms of developing prototypes, contributing code or evaluating technologies. Yet, except in the situation that we decide to write the entire communication on our own we are in a moment to "choose" from existing technologies, not to think about how to create them. This is usually justified for things like IoC, testing and a lot of "amazing" things. Very experienced developers may make a better solution for the company, even if it is not as feature complete as the one bought from another company. Guide to the Software Engineering Body of Knowledge looks at software development, the architecture and the process of it. Offered by University of Alberta. Having the interface is good to avoid the need for adapters if you want to replace the entire "family", but the components can talk to each other knowing by their right types. In fact, the best architecture in such a case is to have the interfaces declared in a common assembly (DLL) and to implement the specific "families" in other DLLs. .NET Architecture Guides. This can apply to nearly all the major Game Engines. Some continue programming indefinitely, while others, eagerly or reluctantly, become managers and climb the corporate ladder. Architecture serves as a blueprint for a system. So, if you have an interface, you can change the actual implementation without problems. Guide to the Software Engineering Body of Knowledge. The Software Architect Code: Building the Digital World. So, calling the event asking to serialize a type that's not serializable (instead of trying to consider it [Serializable]) would be much more appropriate. E-mail addresses are not publicly displayed, so please only leave your e-mail address if you would like to be notified when new comments are added to this blog entry (you can opt-out later). This will only mean that the users will not see the interfaces and the factory all the time. Do you follow what George Fairbanks calls an "architecturally-evident coding style"? save. This is basic… Yet, consider the problem of third-party libraries. The normal arguments I see against frameworks are: And I must say that I mostly agree with all the arguments. The application can't tell how to search the drivers differently. I am not saying that those frameworks don't work. The way that software components — subroutines, classes, functions, etc. An architecturally-evident coding style >>. So, to achieve this, we should use façades. Inscríbete. Well, I just complained about WCF being too attribute based, but you may consider it OK as you will create a new WCF service and implement it as WCF from the start. Note that the first fix is subjective already. That is, I don't ask to serialize a given instance, I ask if there's a serializer for such a type and, if there is, I know that I can serialize other instances of the same type without having to call the event again (yes, I wrote my own serialization framework). A software architect typically works with project managers, discusses architecturally significant requirementswith stakeholders, designs a software architecture, evaluates a design, communicates with designers and stakeholders, documents the architectural design and more. This difference between the architecture and code views is also exaggerated by what George Fairbanks calls the "model-code gap" in his book titled "Just Enough Software Architecture" (highly recommended reading, by the way). Maybe I am getting a little off-topic here, but another thing that annoys me is the now popular idea of Inversion of Control. The [TypeConverter]s in theory can convert any type to any type, but they require the attribute to be used in one of the two types (be it the source or the destination) and a single type-converter must know all the possible conversions. 1. Then, if you want to make it accessible as a real web-service, you create another application that's bound to the service and only fills the information needed to expose the library as a service. I've followed these approaches in the past myself and, although I can get my head around them, I don't find them an optimal way to describe a software system. Usually they aren't as bad, but I consider them to be very annoying. I work as a Software Architect/Systems Architect and many times when I do job interviews it seems that people simply have no clue about what I do. 7. Also, there other kinds of problem. That is, a basic application may implement the service to respond that it doesn't find any translation (and I am already considering the program uses some language, like English, by default), a little better implementation may use a text file to find translations, some other implementations may use specific resource files and some others may redirect to an external service or even find those translations using a database. Continue browsing in r/softwarearchitecture. I recently wrote a post with a sample serialization framework proposal and other practical experience points I collected while making frameworks myself. A software architect has to constantly review the code to ensure the quality of the design by avoiding complexity, advocating clarity and to do this with the team. I just answered that. I am not sure if that's possible in .NET 4.5). This is a very important decision time, as the entire evolution of the application may go better or worse by those initial decisions. I know that most of us simply can't solve the architecture problems of already existing frameworks. So, if you think that you should make every class only talk to other classes by interfaces, well, think again. A Software Architect cannot possibly become a subject matter expert wi… One way to achieve a nice mapping between architecture and code is to ensure that your code reflects the abstract concepts shown on your architecture diagrams, which can be achieved by writing components rather than classes in layers. That is, developers that avoid creating a framework to buy an external one usually finish with their own framework, based on an external one and it usually has the original limitations + the limitations they may have added to it. I especially like your considerations on serialization. Compare this with normal objects that are created, their properties are filled and only later one or more calls are done, without any parameters or with a very reduced list of parameters. A clean mapping between diagrams and code makes a software system easy to explain, the impact of change becomes easier to understand and architectural refactorings can seem much less daunting if you know what you have and where you want to get to. Most ORM frameworks which usually are attribute based, configuration file(s) based and constrained to database-types requiring adapters to be created if we want the data to be presented with application-specific data-types. The code simply can't replace one implementation by another one, as the "start point" is already the service library (be it WCF or another one). Software architecture supposes to reflect business logic and is the most crucial part of software which we should focus on. There are many activities that a software architect performs. That's the case with ADO.NET connections, commands, parameters and the like. :-). If not, why not? Even if you think it is appropriate (and it usually is), it is also very important to avoid repetitions and so, by the same way a type that has the [Serializable] attribute doesn't need to be "added" as valid per serializer instance, it is very important to have global solutions. So, why not call an event at that moment, giving all the information you already have (that is, the instance you are working on, the action you want and the parameters you already have, like a conversion from a value X to a specific type) and let the event tell you if it was able to do the job or not? Actually, if I'm being honest, this matches my own experience of building software myself because I've done the same thing! That's a extremely rigid rule. Yet, as I explained in the IoC topic, simply making every component talk to others by interfaces is bad. But, for many situations, it is better to give some sealed solutions. The patterns automate the creation and lifecycle management of 95 percent to 99 percent of an application’s topology. report. In other words, my primary focus when describing a software system is the static structure, which ranges from code (classes) right up through components and containers. It provides an abstraction to manage the system complexity and establish a communication and coordination mechanism among components. I model this with my C4 approach, which recognises that software developers are the primary stakeholders in software architecture. For web-sites that will be something like ASP.NET + MVC, Web Forms, caching technologies and the like. The very first step towards creating long-lasting software is figuring … Screaming architecture a.k.a. Now I will stop focusing on the fact that I like to create frameworks or on the problems of existing framework as you may be the kind of person that says that you will not create a framework and you will accept the limitations of the existing ones. If we see what's happening in most cases, it is like this: A framework wants some more information to finish its job and to find such an information it may: And, if it isn't able to do that, it simply fails/throws an exception. r/softwarearchitecture. A common architecture problem of SOA consumers is that they call the service library directly to create the service instances and so, even with interfaces that allow the implementation to be replaced, they are completely bound to the technology that implement those interfaces.
