A software expert who makes design choices in high-level terms and dictates the technical standards, like software cold standards, platforms, and tools is called a software architect.
The chief architect is the leading expert.
With the fame of multi-layer application development, the ways of how an application can be designed have also increased in number. With that expansion, the risk that a program development project may carelessly create a product that is supposed to be new but already exists has grown significantly. During software development, a new software architect role has become really necessary.
The software architect idea started to take hold when OOP (object-oriented programming) was coming, in the late 90s and the early 2000s, into more widespread use. Object Oriented Programming granted for more apps to be built, which in turn needed system oversight and an increased high-level application.
Software architect has responsibilities such as: limiting the choices during development by going with a standard way of following the development of the application, defining, choosing, and creating an application framework for the application. Another very important responsibility of the software architect is to recognize the possible reuse in the organization by having knowledge of other applications.
In order for the software to perform these responsibilities in an efficient way, software architects use, very often, UML (Unified Modeling Language) and OOP (Object Oriented Programming) (standardized model and symbols) in order to represent systems or create artifacts. UML has become an important tool for software architects because it allows them to communicate the overall system design to the developers and some other team members, equal to the sketches made by building architects.
Generally, the role of software architects has some common traits: architects make low-level choices much more rarely than they make high-level ones. Further, they sometimes may dictate coding standards, platforms or tools, which represent technical standards and, may also be involved in designing the architecture of hardware environment or totally focus on the designing methodology of the code. Also, these architects can use different software architectural examples that are specialized in describing architecture.
The business and IT sides of an organization are always handled by an enterprise architect who is also involved in the determination of TO-BE and AS-IS statuses both from the business and IT process perspective. Sadly, many organizations are designing the software architects responsibilities within the aspect of Enterprise Architecture. This is done in such way that it up-selles the role of a software architect or/and absorb two different disciplines that are business related, in order to avoid over heading.
A software architect application works very well with just one software application.
Solution architect or System architect are some similar titles in use, but without harmony in their exact meaning. The first one (Solution architect) may refer to someone who is directly involved in advancing a certain business solution, while the other one (System architect) is often used as a synonym for Application Architect.
