Have you ever tried to extract a relationship among the data that your documents carry? Sometimes document-oriented model does not provide us an appropriate structure to collect how the data is related and we need a graph. Manual replication from MongoDB to Neo4j may be painful to be done. This talk will present a tool called neo4j-doc-manager (written in Python, based on mongo-connector project!), that allows you to grab MongoDB events and mirror them to any other database.

Traditionally we consider web sites to be working in an online mode only. If the Internet connection drops, the entire web site stops functioning. Mobile applications, however, change this perception as connection is considered unstable and applications should take necessary measures for good user experience. Now we are able to create web sites that react on changes in the Internet connection and provide certain functionality offline. AppCache, IndexedDB and File API are few of the mechanisms to allow us to store the application and its data in the browser. However, now we have some questions to think about: Who is the master of the data - the client or the server? What data should we download in advance? How do we handle updates of the application? In this talk I will give overview of how web applications can go offline and which precautions we should take.
