Abstract
Waroenk kids collage is a restaurant that sells various types of food menus and is located
in Indonesia, Jakarta. This restaurant has data that accumulates and accumulates without
any continuation of that data. This is not supported by the final report. Therefore, it is
necessary to build a data warehouse that can be used as information for waroenk restaurant
owners for college children. One of the important processes in the operation of the data
warehouse is the process of copying data from the operational database. Before the data
enters the data warehouse, the ETL (extract, transform, load) process is carried out on the
data. This scheme is designed for the data warehouse at Waroenk Anak Kampusan using the
Snowflake Schema model. The results of the research show that the Waroenk Anak Kampusan
data warehouse has four tables (product table, price table, service table and customer
dimensions), has one real table, namely the Sales table. All sales data can be monitored by
the owner and can find out the total sales data.

1. Introduction
Data warehouse is a system that can combine data from various sources into a single data
repository, implement and consistently support business analysis [1] From that explanation,
several journal references were found, such as, [2] Design and Implementation of sales data
warehouse (Case Study : Northwind Sample Database) By M. Firdaus Zulkarnain, Ni Putu
Novia Ardiyanti, I Wayan Wijaya K Sandi, I Dewa Ngurah T Hendrawan, Ida Bagus M
Mahendra in 2021 resulted in the data warehouse integration process using the ETL concept
with the help of Pentaho Data Integration. [3] Implementation of Data Warehouse and Sales
Data to Determine Strategic Plan for Batik Sales (Case Study of Batik Mahkota Laweyan) by
Fatah Yasin Al Irsyadi in 2014 resulted that all monitoring of data on Batik Mahkota
Laweyan products was carried out using a cube browser. [4] The design of a data warehouse
to support executive information systems at the Ummu'L Quro foundation in Depok by
Syamsul Bakhri1, Yamin Nuryamin in 2018 the results have that a database and its
applications can be carried out to analyze transactional information that occurs in the
education unit at the Ummu'l Quro Foundation, Depok, which is used to support the decision-
making process by the leadership. From some of the references above, a data warehouse is
designed that can be used as a good source of information for waroenk owners for college
students related to sales strategies for the future with price, taste quality, customer discounts.
