More on Media Bistro.

Time entry has so far always been a huge pain in the a!@# at every company I’ve worked for, no matter whether Excel, automated versions, especially the horrid Oracle application we’re currently using — it’s slow, annoying, only behind the corporate firewall.

Timeline puts all that into my phone, search for the project, snap in the code, put in the hours, fill the rest of the week up with the placeholder entries and submit the entire thing at the end of the week.

The only downside is that it has to be manually installed by dragging it into iTunes — no updated via the store. Either way, major kudos to the Razorfish IT team, I finally have a totally easy way to report my time cards. They have my vote for any iPhone innovation award out there :-)

On a side note, it is almost impossible to type on an iPhone on a moving train.

After the success of RoR, the problems of the JEE platform became clear to everyone. Even if Grails or RoR suddenly disappear, from now on the new frameworks that will emerge will be following this “new” philosophy. And taking into consideration that Grails was developed since it’s begining focusing on the Java developer, it’s an undeniable fact that it will have a huge influence over all the new developments on this area from now on.

Day Software AG (Day) led the development of a JAVA specification which defines a uniform application programming interface (API) to manage content. This specification is called content repository API for java (JCR) and is part of the java community process. Implementations of this specification are actually provided by well known companies such as Oracle, Day or Alfresco.

JCR implementations are often used to build high level content management systems and collaborative applications. Day also provides an open source implementation of the specification which is called Jackrabbit and which is used as a shell for some of its products.

This diploma thesis takes place in this context. Day wants to clarify some points which relate to the data model promoted by their specification. The basic idea is to compare their approach to managing content with the approach promoted by competitors at different levels. The following sections will clarify the approach adopted to do this and give an overview of the content developed in this report.

As explained, the purpose is to locate JCR in the database world. This work will be done by comparing the relational model and the model promoted by JCR. The relational model defined by Codd in the 70’s is actually the most widely used data model. The unstructured or semi-structured model subtended by the JCR specification encounter a growing success in the content management area. These two models will be described and analyzed in this report.
