Lab: Postgres Crime Reports
Building a Database for Crime Reports
Using PostgreSQL for storing data related to crimes that occurred in Boston. Dataquest provided the dataset boston.csv
for input. We will:
- Create the table
boston_crimes
- Create the table with the appropriate data types for storing the information from
boston.csv
- Store the table inside the schema
crimes
- Create the user groups
readonly
andreadwrite
with appropriate privileges - Create the users
data_analyst
anddata_scientist
and assign toreadonly
andreadwrite
groups, respectively - Verify if the privileges of user groups are set accordingly
To accomplish these goals in this lab, you would have to perform the following:
- Create the required database and schema after installing PostgreSQL and
psycopg2
module - Explore the column headings and content of
boston.csv
to determine the appropriate data types - Create the required table using the appropriate data types
- Load the data from
boston.csv
into the table - Create the user group
readonly
which has the following privileges: database connection, schema usage, and data selection from all tables in the schema - Create the user group
readwrite
which has similar privileges withreadonly
and capable of inserting, deleting, and updating the data in all tables in the schema - Create the requested users and assign them to their respective user groups
- Test the database if correct objects is created and users/groups have the right privileges
