Data recovery system based on fountain code in cloud storage Peng Chen Lanchang Guo Yan undistracted Storage Service has a portable and easy-to-use feature as a new data storage and management service, but it is also accompanied by an important issue: how to ensure the integrity and recoverability of the data. To resolve this problem, A data recovery system based on fountain Code is designed and implemented. The scheme uses fountain code to encode data to ensure the data can be recovered under certain tamper ratio, and the time complexity of hash function is verified when data integrity is validated. When users are worried about tampering with their data, simply challenge the server, depending on the service ...

The application of MongoDB in Call center system Shi, Gianschopo MongoDB is an extensible, high-performance, modeless, file-based data management system based on document storage. The feature of document-oriented storage makes the MongoDB can support the storage of loose structure data, the weak consistency feature makes the MONGODB can guarantee the faster user access speed, the high performance characteristic makes the MongoDB can better support the processing of large data quantity. The continuous development of the call center has put forward the new request to the data storage System: Large data quantity + loose data structure + high interview ...

[REVIEW] If I want to give each user to provide 1G of network storage space. And if the server has a 1000G hard drive can be used to provide all users with data storage, if each user can be assigned to the largest storage space 1G, then how many users can be allocated to use it? Some time ago, Xiaobian use Baidu network disk, suddenly found, 咦? Baidu network disk exclamation can receive 2TB space for free! Network hard disk we may have more or less have touched, have to say, in this era of all things cloud, it can be said is a ...
