\section{Introduction} For the master course Advanced Databases (2ID45), we chose to create a liquor database. The project is called ”Pottepei” which is Flemish (Brussels) for a drunk. To access the database we made a web interface, which can be found at "pottepei.schinagl.nl". \\\\ This document will discussed the inside view of the project. The general description of the project can be read in chapter 2. What does the website do? And an overview of the techniques that were used to complete the project. \\\\ In the next chapters we will go further into details about the techniques we used. In chapter 3 we will discuss all the XML aspects of the project. Which XML files were used? And how they look like. Also the purpose of the files will be discussed. \\\\ In chapter 4 we will explain which query's we used to retrieve some goals. Some query's will be given and explained. And finally we come up with a conclusion.
