into the Packages Collection. This package is meant to support data
warehousing in a much more efficient manner than traditional RDBMSs.
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.
Please note that the storage required for this package could be viewed
as being quite extreme - the standard build and data occupies in excess
of 20 GB, and that is all installed into ${PREFIX} at installation
time.
