In this case study we will describe the evolution of the CanalDVD project which started as a Zope and Oracle isolated web site but bacame a distributed Zope application using the ZODB as the main data storage.
CanalDVD.COM.BR is a Brazilian online catalog of DVDs which syndicates its content to other web sites. It was developed in the year 2000 as a Zope 2.2 application connected to an Oracle database. The catalog itself was stored in about 30 Oracle tables, representing entities such as Film, Genre, Actor, Languages, Special features etc. Application logic, templates, news articles and some images were stored in the ZODB.
In 2001 CanalDVD decided to license its content to multiple client web sites. However, the cost and complexity of deploying and synchronizing Oracle servers at each client site prompted Hiperlógica to rewrite the entire application as a Zope-only solution. That was the motivation for converting CanalDVD from a relational schema into a an object-oriented database implemented in ZODB.
