+ <body><h1>Preparations</h1><p>Download this <a
+ href="/files/goik/Sda1/EmployeeCompany/dujewdh323FggFFD_72w.zip"
+ target="_blank">Maven skeleton archive</a>, unzip it and import the
+ resulting sub directory <code>Skeleton</code> as a Maven project into your
+ Eclipse workspace. This project contains:</p><ol>
+ <li><p>A schema file <code>src/main/resources/company.xsd</code>
+ describing company and employee data as being provided in the sample
+ instance <code>src/main/resources/employees.xml</code>.</p></li>
+
+ <li><p>A Java skeleton class
+ <code>de.hdm_stuttgart.mi.sd1.employeecompany.Xml2Rdbms</code>
+ containing boilerplate code being related to <code>Jdom</code> and
+ <code>Jdbc</code>.</p></li>
+ </ol><h1>Description</h1><p>This exercise's aim is to transfer XML file
+ data like being represented by <code>src/main/resources/employees.xml</code>
+ to a relational database system via <code>Jdbc</code>. You are expected to
+ solve two tasks:</p><ol type="i">
+ <li><p>Create a SQL-DDL schema which best resembles the XML schema
+ <code>src/main/resources/company.xsd</code>.</p><p>Hint: Since employees
+ belong to a specific company (composition) you'll need two tables being
+ connected by a foreign key relation.</p></li>
+
+ <li><p>Complete the implementation of
+ <code>de.hdm_stuttgart.mi.sd1.employeecompany.Xml2Rdbms.java</code> to
+ read XML data and write it to your database server.</p><p>Hint: With
+ respect to the foreign key reference connecting employees and companies
+ you'll have to invent <code>id</code> values for company datasets. This
+ may be accomplished by simply enumerating all companies appearing in
+ your XML input data.</p></li>
+ </ol><p>Upon completion zip up your project directory and upload it to the
+ E-learning system. Mind the remaining time! <strong style="color: red;">When
+ the examination terminates no subsequent uploads will be
+ possible!</strong></p></body>
