The case for a wide-table approach to manage sparse relational data sets
2007
Proceedings of the 2007 ACM SIGMOD international conference on Management of data - SIGMOD '07
A "sparse" data set typically has hundreds or even thousands of attributes, but most objects have non-null values for only a small number of these attributes. A popular view about sparse data is that it arises merely as the result of poor schema design. In this paper, we argue that rather than being the result of inept schema design, storing a sparse data set in a single table is the right way to proceed. However, for this to be the case, RDBMSs must provide sparse data management facilities
