C-Store: A column-oriented DBMS

Interesting: C-Store - C-Store is a read-optimized relational DBMS that contrasts sharply with most current systems, which are write-optimized. Among the many differences in its design are: storage of data by column rather than by row, careful coding and packing of objects into storage including main memory during query processing, storing an overlapping collection of column-oriented projections, rather than the current fare of tables and indexes, a non-traditional implementation of transactions which includes high availability and snapshot isolation for read-only transactions, and the extensive use of bitmap indexes to complement B-tree structures. I'm hooked...I'll have to check this out!

    Without actually looking at it, it sounds like a good dump for reporting and mining - I'll try to remember to check it out.
