General information about SMPR software system. System consists of a core and
a set of specialized modules, which are responsible for solution of certain class tasks.
The core creates modules functioning environment with ability of solving tasks in
parallel and sharing data between modules. It consists of the common interfaces, data
exchange standards, boost and information systems about module.
The core comprises a buffer that is the intercommunicator between modules.
Buffer can manipulate various source data, as well as the results of their processing. It
is the "environment" of the system-level data, i.e. data that can be accessed by any
module. At the architectural level, the buffer is represented as a special class providing
the interface for data download, store and validate for interior modules. The core of the
system is not specified for specific algorithms of a particular course. Specifics of a task
are provided only by the set of exterior modules, which is available to be used by the
core. This facility of the system core allows to use it as the basis for development of
training-methodological systems for various training courses possessing structure
“tasks class – their solution methods” with the ability to exchange data between classes.
Structure of a module responsible for a particular class of tasks is constructed in such
way that the core can automatically detect not only the presence of the module, but also
some of its characteristics (period of usage, number of attempts to use, etc.). The
system is designed with enhancement of its functionality by adding new classes of tasks
and methods for solving existing tasks. A new module project implementing abstract
classes inserted at the design stage is creating to extend the list of classes of tasks to be
solved. The formed project is compiled into a library that is added to the plug-in folder
(padding) of the system. New function will be added automatically to the main menu
of the projects after the software package start-up. Adding of new tasks solution
methods is implemented slightly differently. It needs familiarization with the abstract
class of a specific module. Each project of a module, as well as project pattern, has a
special folder containing files with tasks solution methods classes for specific modules.
Adding of a new method performs as addition of a new file in the folder where method
class will be implemented, then the entire project must be recompiled. Since the system
consists of a core and a number of modules provided in the form of plug-ins, the
presence or absence of a single module does not affect the operation of other modules
of the system. The scheme of the individual modules is shown in Figure 1.
