This paper quantifies the scalability of a document store named MongoDB and an extensible store named HBase for processing simple operations using a social networking benchmark named BG (www.bgbenchmark.org). We report on the vertical and the horizontal scalability of both data stores. We quantify speedup and scaleup characteristics of each data store's Social Action Rating (SoAR). SoAR is the highest...
In this paper we present a software architecture for a Knowledge Management and Processing Framework initially for usage in the agricultural domain, but customizable for any domain. In contrast to existing Knowledge Management and Processing Systems, this proposed architecture mainly focuses on the usage of a cloud platform as execution environment and therefore pays special attention to the design...
We propose the client-side AES256 encryption for a cloud SQL DB. We trust the safety of the cloud DBS run-time values, e.g., through a moving target defense. The client may send AES key(s) with the query. These become run-time values for on-the-fly decryption of ciphertext into plaintext for query evaluation. The DBS clears all these values at the query end at latest. The scheme functionally offers...
