Every research and development is started from a state-of-the-art review. Such review is one of the most labor- and time-consuming parts of research, especially in high technological areas as computers and software engineering. It is strongly necessary to take into account and reflect in the review the current stage of development. A researcher must find appropriate references, to read it and make a critical analysis to determine what was done well before and what was not solved till now, and determine and formulate his future scientific aim and objectives. To help researchers save time and taxpayers money, we have started to publish 'Advances in Computers and Software Engineering: Reviews'open access Book Series. The first volume of 'Advances in Computers and Software Engineering:Reviews', Book Series contains 6 chapters written by 21 authors from 7 countries: Brazil, Canada, Palestine, Slovakia, Spain, Taiwan and USA.
