WITH THE INCREASING NUMBER OF MOBILE DEVICES IS NECESSARY TO CREATE SOLUTIONS ADAPTED FOR THESE TYPES OF DEVICES THAT HAVE LIMITED PROCESSING CAPACITY, MEMORY AND BANDWIDTH SUFFICIENT TO CONSIDER WE PROPOSE A MODEL BASED SYNCHRONIZATION MESSAGE RELATIONAL DATABASES TO SYNCHRONIZE BETWEEN MOBILE DEVICES AND SERVERS, IN ORDER TO MINIMIZE DATA TRANSFER BETWEEN THE DEVICE AND THE SERVER, MINIMIZING PROCESSING BY THE MOBILE DEVICE. IN THIS MODEL, SYNCHRONIZE DATABASE AND MOVE TO A MOBILE DEVICE DATABASES OF MOBILE DATA SERVICES TO THE MASS OF THE PLANETS WILL BE DISCUSSED.

1. INTRODUCTIONTHE INTERNET IS BECOMING AN INCREASINGLY VITAL TOOL IN OUR EVERYDAY LIFE, BOTH PROFESSIONAL AND PERSONAL, AS ITS USERS ARE BECOMING MORE NUMEROUS. IT IS NOT SURPRISING THAT BUSINESS IS INCREASINGLY CONDUCTED OVER THE INTERNET. PERHAPS ONE OF THE MOST REVOLUTIONARY CONCEPTS OF RECENT YEARS IS CLOUD COMPUTING. THE CLOUD, AS IT IS OFTEN REFERRED TO, INVOLVES USING COMPUTING RESOURCES -HARDWARE AND SOFTWARE – THAT ARE DELIVERED AS A SERVICE OVER THE INTERNET (SHOWN AS A CLOUD IN MOST IT DIAGRAMS). MANY COMPANIES ARE CHOOSING AS AN ALTERNATIVE TO BUILDING THEIR OWN IT INFRASTRUCTURE TO HOST DATABASES OR SOFTWARE, HAVING A THIRD PARTY TO HOST THEM ON ITS LARGE SERVERS, SO THE COMPANY WOULD HAVE ACCESS TO ITS DATA AND SOFTWARE OVER THE INTERNET.THE USE OF CLOUD COMPUTING IS GAINING POPULARITY DUE TO ITS MOBILITY, HUGE AVAILABILITY AND LOW COST. ON THE OTHER HAND IT BRINGS MORE THREATS TO THE SECURITY OF THE COMPANY’S DATA AND INFORMATION. AT AN EQUALLY SIGNIFICANT EXTENT IN RECENT YEARS, DATA MINING TECHNIQUES HAVE EVOLVED AND BECAME MORE USED, DISCOVERING KNOWLEDGE IN DATABASES BECOMING INCREASINGLY VITAL IN VARIOUS FIELDS: BUSINESS, MEDICINE, SCIENCE AND ENGINEERING, SPATIAL DATA ETC. THE EMERGING CLOUD COMPUTING TRENDS PROVIDES FOR ITS USERS THE UNIQUE BENEFIT OF UNPRECEDENTED ACCESS TO VALUABLE DATA THAT CAN BE TURNED INTO VALUABLE INSIGHT THAT CAN HELP THEM ACHIEVE THEIR BUSINESS OBJECTIVES. [ALEX BERSON (AUTHOR), STEPHEN J.SMITH (AUTHOR), BERSON (AUTHOR), KURT THEARLING (AUTHOR), 2013, ROGER JENNINGS, 2014,MERRIAM-WEBSTER, 2012]IN BAYESIAN ANALYSIS, PRECISE A-PRIORI DISTRIBUTIONS ARE OFTEN NOT AVAILABLE. TO CAPTURE SUCH UNCERTAINTY, A MORE GENERAL FORM OF A-PRIORI INFORMATION CAN BE EXPRESSED BY USING SOFT MODELS. THE MATHEMATICAL BASES FOR SUCH MODELS ARE FUZZY NUMBERS AND FUZZY VALUED FUNCTIONS, ESPECIALLY THE SO-CALLED FUZZY PROBABILITY DENSITIES. BASED ON THESE GENERALIZED PROBABILITY DENSITIES, BAYES’ THEOREM CAN BE GENERALIZED. MOREOVER, THE CONCEPTS OF PREDICTIVE DISTRIBUTIONS AND STATISTICAL DECISION MODELS CAN BE ADAPTED ACCORDINGLY. THESE CONCEPTS YIELD MORE REALISTIC APPROACHES FOR CAPTURING THE UNCERTAINTY OF DATA AND A-PRIORI INFORMATION. [MARK JEFFERY, 2013].

THANKS TO COMPUTER NETWORKS AND ADVANCEMENTS IN ELECTRONIC SCIENCE, CLOUD COMPUTING NETWORKS WITH OFF-SITE ACCESSIBILITY MAKE IT POSSIBLE FOR USERS TO COMMUNICATE WITH ONE ANOTHER. CLOUD COMPUTING IN RELATION TO YOUR SOFTWARE IS STILL IN ITS INFANCY. WHEN RESOURCES ARE NOT IN USE, THE TOTAL COST OF GOING TO THE CLOUD IS ALMOST ZERO. SO IT'S NO SURPRISE THAT SCIENTIFIC AND INDUSTRY RESEARCH IS MOVING TOWARD CLOUD COMPUTING. WHEN IT COMES TO DISTRIBUTED SYSTEMS AND MULTI-AGENT APPLICATIONS IN CLOUD COMPUTING NETWORKS, SECURITY ISSUES ARE A MUST-HAVE REQUIREMENT. IN ORDER TO AVOID THESE CONCERNS, INTRUSION DETECTION SYSTEMS AS WELL AS A SERIES OF SECURITY FRAMEWORKS HAVE BEEN INTRODUCED. IN THIS RESEARCH, WE TRY TO STUDY THE METHODS PRESENTED INTELLIGENTLY, INTRUSION DETECTION SYSTEMS AND PROPOSED FRAMEWORKS IN THE CLOUD COMPUTING NETWORK.
