In recent years, due to the widespread use of electronic services and the use of social network as well, large volumes of information are being made that this information contains various types of things such as videos, photos, texts etc. besides large volume. Due to the high volume and the lack of specificity of this information, covering them through traditional and relational databases is not possible and modem solutions should be used for processing them, so that processing speed is also covered. Data storage for processing and the way of accessing to them in memory, network communication, covering required features for distributed system in solutions that are in use for storing big data, are the items that should be covered. In this paper, a collection of advantages and challenges of big data, special features and characteristics of them has been provided and with the introduction of technologies in use, storage methods are studied and research opportunities to continue the way will be introduced. 展开更多
