Abstract: Platforms and mechanisms for multi-source data management are provided. In accordance with one aspect, a knowledge mining engine comprising an on-line knowledge mining component supporting multi-dimensional queries for on-line knowledge mining of multi-source data and an off-line knowledge mining component for running knowledge mining procedures for off-line knowledge mining of the multi-source data. The multi-source data management platform/mechanism may also include an adaptive data collector to collect data actively and passively, a data analysis cascade to cleanse and analyse the multi-source data concurrently and separately, a data integration cascade to consolidate and integrate the multi-source data according to multiple data integration dimensions, a centralized data repository implementing RESTful APIs for data CRUD operations and storing multi-source data generated in the platform, and a data sharing portal to share data and mined knowledge to users and up-layer applications.

Abstract: A systematic distributed storage system (DSS) comprising: a plurality of storage nodes, wherein each storage node configures to store a plurality of sub blocks of a data file and a plurality of coded blocks, a set of repair pairs for each of the storage nodes, wherein the system is configured to use the respective repair pair of storage nodes to repair a lost or damaged sub block or coded block on a given storage node. Also a distributed storage system DSS comprising h non-empty nodes, and data stored non homogenously across the non-empty nodes according to the storing codes (n,k). Further a method for determining linear erasure codes with local repairability comprising: selecting two or more coding parameters including r and δ; determining if an optimal [n, k, d] code having all-symbol (r, δ)-locality (“(r, δ)a”) exists for the selected r, δ; and if the optimal (r, δ)a code exists performing a local repairable code using the optimal (r, δ)a code.
