CDO – Connected Data Objects

Introduzione a CDO Questo framework, che è un componente del progetto EMF, permette la condivisione di un modello EMF. Se con Teneo quindi possiamo fare in modo che ciascun client possa accedere ad un database (realizzando un client/server a due livelli), con CDO abbiamo la possibilità che i vari client accedano ad un server che mette loro a disposizione la medesima istanza, condivisa, del modello EMF. In questo tutorial vedremo come: installare CDO creare un server CDO creare un client CDO Per una documentazione dettagliata su CDO potete consultare il seguente link Mentre qui potete scaricare le varie versioni [...]

Eclipse EMF: updating the Model

Now we will see how to handle a Model update. Let's say we want to add the "surname" attribute to Author entity. Open the model diagram (Library.ecorediag) and add the new attribute still of EString type Save the changes (Ctrl-S), re-open file Library.genmodel, and re-generate the sources for the following plug-ins: Model, Edit and Editor (remember to click on each of the first three context-menu items) Re-launch the application (doing a Clean and checking the launch, in case of errors)   If you check the database now, you'll find that table "author" has a new "surname" field, which the application [...]

Eclipse EMF: an out-of-the-box CRUD for a database

This tutorial assumes that you have followed these other tutorials in the specified order: Eclipse EMF: Designing the Model Eclipse EMF: a CRUD at no-cost the goal here is to show how, with just some extra lines of code added to the EMF generated plugins, we can have our model persisted and maintained on a database. We will use MySQL as the target database, so make sure you have the access to such a database server (you can always download it at We'll use the "test" schema (pre-loaded empty while installing MySQL); anyway you can use another schema simply [...]

Teneo Setup for Eclipse 4.2 – Juno

In this section we will see how, starting from Eclipse Juno Modeling, you can install some plugins that will allow management of the persistence to a database using the Teneo framework. This framework implements a layer that links EMF and ORMs like Hibernate or EclipseLink, which in turn handle the persistence on relational databases. The advantage, in using Teneo, is that you can act at EMF level and hit the database, without knowing the intermediate mechanisms. Regarding the database choice, in this series of articles, we will work with MySQL as target database. Go to menu Help -> Install New [...]
