+## What is Hivemall?
+
+[Apache Hive](https://hive.apache.org/) is a data warehousing solution
that enables us to process large-scale data in the form of SQL easily. Assume
that you have a table named `purchase_history` which can be artificially
created as:
+
+```sql
+create table if not exists purchase_history
+(id bigint, day_of_week string, price int, category string, label int)
--- End diff --
`gender string` is missing.
