Software Architecture: Virtual Structure
Software architecture is basically the way software programs
are put together. A software designer must take into consideration a
number of different things when putting together software, such as
whether this software is going to be used by a standalone computer or a
networked system of computers; just like when one builds a house,
software architecture determines the final look and efficiency of a
software package.
Software architecture can be built around either in-line programming or
around an object-oriented programming language. In-line programming is
the old fashioned way, where the architect specifies everything one
line at a time, and the computer executes each line in order. Object
oriented programming is radically different, and much more efficient;
instead of executing line by line, the programmer defines “objects,”
like characters, items, or actions in a video game; the computer
creates these objects and delivers them up when the program calls up
the objects.
After the programming language is determined, the programmer defines
things like the GUI, or graphical user interface; this is what we
actually see when we use the program. He determines how the program is
going to install itself into your computer – which files it actually
goes into, whether all the program will be on your computer or if part
of it will be on a server, or even on the web. File-structure
architecture is important in database programs and with web sites; this
determines how files link together or how files are stored to be easily
accessible by either the user or the computer.
Together, all these structural considerations will determine how your
program looks, how it functions computer-to-computer, and how
efficiently it operates. Good software architecture takes advantage of
your system’s strong points and minimizes the weak points. It is more
important than most people consider, or even realize.
