Abstract: In today’s world the problem of processing and storing huge amounts of data becomes increasingly pressing. Messages in social networks, photos, streaming video – altogether creates a high load on the server-side software. For this reason common approaches used in desktop-software design may be ineffective since they don’t take into account the huge load on the application created by the vast number of users. Currently, there is no clear definition for highly-loaded systems. In most cases this term is used in situations, when software fails to operate under some momentary load. There’s no specific values set at which a system can be considered highly-loaded, since each software is different and same amount of requests can lead to completely different loads on the resources. The given study of the database management systems consisted of several experiments, measuring the speed of common operation on databases, such as adding, selecting and deleting. Based on the result of these experiments the author makes conclusions and gives recommendations on choosing the database management system. The article reviews approaches in developing highly loaded systems, highlights their features and disadvantages and shows examples of the use of these approaches in popular web-services such as ÂÊîíòàêòå, Facebook, Google and ßíäåêñ. The articles brings a comparative analysis of MySQL and MongoDB database management systesms. In conclusion the author gives recommendations on selecting a database management system depending on the approach to designing architecture of a highly-loaded project.
