# java-cli-bloop-sbt-postgres-com-tbl-exp
2+

## Description
4+
Creates a small database table
5+
called `dog`. This table, `dog`, has been normalized to 3NF.
6+
Two new tables have been added, `breedLookup` and `colorLookup`.
7+
Creates a new table `dog_expanded` that joins
8+
`dog`, `breedLookup` and `colorLookup`. Added clustered indexes on
9+
`dog`.breedId and `dog`.colorId. Turned `dog_expanded` into a view with an
10+
implicit index on `dog_expanded`.id. Using an common table expression with the aggregate function
11+
COUNT, create a new view `breed_count`. All output normally
12+
seen in a terminal will be in `java-srv/log` which will dump to the screen. The project may seem to hang but the logs from the container must be written to the project this can take up to 3 min.
13+
14+
Compiled and ran from build server `bloop`.
15+
16+
