Portal's db custom usage?

Question

Hello,
Is it possible to use portal's db to store any data that my
application might require? Is there any APIs at the portal
that allow to work with portal's db (create tables/add records/
remove/update)? If not, where and how my own portal application
can manage all the required data?
Thank you,
Yuri

Okei,
This document describes everything you need to know :
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/Use%20SAP%20J2EE%20Database%20Pooling%20Service
The code given in this pdf is (with some modifications, could do a lot of compacation in order to increase readability)
public Connection getConnection () {
InitialContext m_ctx = null;
DataSource m_ds = null;
//note  LocalPool is the pool Alias.
String m_datasource_name = "jdbc/LocalPool";
String m_contextUrl = "";
String m_contextFactory
  = "com.inqmy.services.jndi.InitialContextFactoryImpl";
Connection con;
Properties properties = new Properties();
properties.put  (InitialContext.INITIAL_CONTEXT_FACTORY,m_contextFactory);
try{
  //getting JNDI InitialContext
  m_ctx = new InitialContext(properties);
  //getting the Datasource from the context
  m_ds = (DataSource)m_ctx.lookup(m_datasource_name);
  //getting the connection from the Datasource
  con = m_ds.getConnection();
  return con;
}catch (NamingException ne){
  //pool not created in J2EE. Handle this in someway
  ne.printStackTrace();
  return null;
}catch (SQLException sqle){
  //could not get connection from database
  //perhaps database is down or J2EE pool points
  //to wrong database url
  sqle.printStackTrace();
  return null;
}catch (Exception e){
   //some other exception might happen (don't
   //think you need this
   e.printStackTrace();
   return null;
