Data Modeling and MongoDB

Please join us for a presentation on Wednesday March 14th at 6:30pm by Brandon Diamond of 10Gen about data modeling with MongoDB.  Brandon will be doing a remote appearance using WebEx for the St Louis and Toronto users groujps.


Here's a description of his talk.


"One of the challenges that comes with moving to MongoDB is figuring how to best model your data. While most developers have internalized the rules of thumb for designing schemas for RDBMSs, these rules don't always apply to MongoDB. The simple fact that documents can represent rich, schema-free data structures means that we have a lot of viable alternatives to the standard, normalized, relational model. Not only that, MongoDB has several unique features, such as atomic updates and indexed array keys, that greatly influence the kinds of schemas that make sense. Understandably, this begets good questions: Are foreign keys permissible, or is it better to represent one-to-many relations withing a single document? Are join tables necessary, or is there another technique for building out many-to-many relationships? What level of denormalization is appropriate? How do my data modeling decisions affect the efficiency of updates and queries? In this session, we'll answer these questions and more, provide a number of data modeling rules of thumb, and discuss the tradeoffs of various data modeling strategies.

    How can I verify if there are active meetings in the STL MongoDB space?

    Too bad that I just found this meetup. I have been trying to convert a project that uses MySQL over to MongoDB. Learning to model for MongoDB sure has been a different kind of experience, that is for sure.
