Http://www.cnblogs.com/xbinworld/p/4273506.htmlSparse matrix refers to the matrix elements are mostly 0 of the matrix, in fact, the actual problem of large-scale matrices are basically sparse matrices, a lot of sparsity in 90% or even more than 99%. So we need to have an efficient sparse matrix storage format. This article summarizes several typical formats: Coo,csr,dia,ell,hyb.(1) Coordinate (COO)This is the simplest of a format, each element needs t

Database Design-semi-structured storage and database structured storage Business scenario: the user fills in some documents, reports them, and approves them.
