  8. Query optimization - Wikipedia

    en.wikipedia.org/wiki/Query_optimization

    The result of a query is generated by processing the rows in a database in a way that yields the requested information. Since database structures are complex, in most cases, and especially for not-very-simple queries, the needed data for a query can be collected from a database by accessing it in different ways, through different data ...

  9. P-Grid - Wikipedia

    en.wikipedia.org/wiki/P-Grid

    In distributed data storage, a P-Grid is a self-organizing structured peer-to-peer system, which can accommodate arbitrary key distributions (and hence support lexicographic key ordering and range queries), still providing storage load-balancing and efficient search by using randomized routing.
