What do databases do well?

● General set operations; dealing with large numbers of rows efficiently

● sorting on integer indexes● filtering (WHERE clauses)● joining tables ● aggregating (sums, averages)

What do databases not do well?

● repeated calls to the engine● sorting, filtering and joining on unindexed fields (and

somewhat with text fields)● synchronization

Writes are More Expensive Than Reads

● Set default values, integrity rules, other housekeeping● all involved index columns must be updated as records

are inserted● As the indexes grow so does the time needed to update

each successive record ● Not generally a day-to-day issue but comes into play with

large imports

● It’s easy to roll back when things don’t work● Committing often and on specific parts of a project

makes it easy to track what changed and when, and possibly just ‘roll back’ individual commits instead of restoring all the way back to an older date
