# clientsdb
Have you ever been looking for a ready to use database while doing training?
Search no more, this docker is an image with a client review database inside a postgre, to be used for teaching.
The titles and comments are extracted from the [Amazon review database](https://www.kaggle.com/bittlingmayer/amazonreviews) which lead to a [Google Drive](https://drive.google.com/drive/folders/0Bz8a_Dbh9Qhbfll6bVpmNUtUcFdjYmF2SEpmZUZUcVNiMUw1TWN6RDV3a0JHT3kxLVhVR2M) link that contains "amazon_review_full_csv.tar.gz" (the original dataset used here).
Then the two columns date and name being randomly generated in R.
The code to prepare the dataset is in [data-prep.R](data-prep.R) — the dataset is not on GitHub because of space concerns.
The main purpose of this image is to provide a "real life" tool for teaching databases.
Info:
- the POSTGRES_DB used is clients
- the POSTGRES_PASSWORD is verysecretwow
- the POSTGRES_USER is superduperuser
To launch the db, do:
```
docker run --rm -d -p 5432:5432 colinfay/clientdb:latest
```
Then, for example from R:
```r
library(DBI)
con <- dbConnect(
RPostgres::Postgres(),
dbname = 'clients',
host = 'localhost',
port = 5432,
user = 'superduperuser',
password = 'verysecretwow'
)
dbListTables(con)
# [1] "clients"
res <- dbSendQuery(con, "SELECT title, name, date FROM clients LIMIT 5")
dbFetch(res)
# title name date
