Black-box modernization (or wrapping) provides a new interface to a legacy component. In other words wrapping removes mismatches between the interface exported by a software artifact and the interfaces required by current integration practices.

Complete technology migration includes initial business processes analysis, business requirements documenting, system requirements specification, overall system architecture development, subsystem-level technical design. Complete migration implies complete source code rewriting according to the state-of-the-art programming standards and the practices. Whole product development lifecycle is fulfilled during this way of project works execution.

Computer software, or just software, is a collection of computer programs and related data that provide the instructions for telling a computer what to do and how to do it. In other words, software is a conceptual entity which is a set of computer programs, procedures, and associated documentation concerned...

Direct source code porting does not imply any changes to the system architecture, subsystem-level technical design development, and source code structure optimization/refactoring. Direct porting will ensure system compatibility with prospective operating systems/technologies. Specific source code stability and robustness is a subject for future system testing

There is a huge interest in embedded systems now, and the reason for this is the growing nesessity to have numerous smart devices working together for various tasks, business and personal. It seems to be a long-lasting trend. There are some importanrt impacts of embedded systems, such as minimization of...

Gradual technology migration started with preceding system module breakdown, overall system architecture development, and further module-by-module development process. Module-by-module development process includes system requirements specification, subsystem-level technical design, and further source code development according to the state-of-the-art programming standards and practices. In process of gradual technology migration, complete functionality of...

Information Systems is an academic/professional discipline bridging the business field and the well-defined computer science field that is evolving toward a new scientific area of study. An information systems discipline therefore is supported by the theoretical foundations of information and computations such that learned scholars have unique opportunities to explore...

Information technology (IT) is the acquisition, processing, storage and dissemination of vocal, pictorial, textual and numerical information by a microelectronics-based combination of computing and telecommunications. The term in its modern sense first appeared in a 1958 article published in the Harvard Business Review, in which authors Leavitt and Whisler commented...

Information  systems  are  one of the critical  assets for modern  enterprises  and  these systems incorporate  key  knowledge  acquired  over the organization lifecycle.  These systems must be updated continuously to reflect evolving business practices.  Significant number of organizations in recent years has invested in centralized, mainframe-oriented software development. These software systems,...
