The need to track changes to web content and provide for draft or preview functionality is common to many web applications today. In relational databases it has long been common to accomplish this using a recursive relationship within a single table or by splitting the table out and storing version details in a secondary table. I’ve recently been exploring the best way to accomplish this using MongoDB. A few design considerations Data will be represented in three primary states, published, draft and history. These might also be called current and preview. From a......

I have a RESTful SaaS service I created which uses MongoDB. Each REST call creates a new record in a statistics collection. In order to implement quotas and provide user analytics, I need to process the statistics collection periodically and generate meaningful analytics specific to each user. This is just the type of problem map reduce was meant to solve. In order to accomplish this I’ll need to do the following: Map all statistics records over a time range Reduce the number of calls, both authenticated and anonymous Finalize to get the sum......

Security in MongoDB is relatively young in terms of features and granularity. Interestingly, they indicate that a typical use case would be to use Mongo on a trusted network “much like how one would use, say, memcached.” MongoDB does NOT run in secure mode by default. As it is, the features that are available are standard, proven and probably sufficient for most use cases. Here’s a quick summary of pros and cons. Pros Nonce-based digest for authentication Security applies across replica set nodes and shard members Cons Few recent replies on security wiki......

MongoDB - Boise Code Camp 2012

Welcome to Boise Code Camp, 2012. This year I decided to present on MongoDB. In a previous presentation on MongoDB and some video training I cover installation and configuration and using replica sets. For the code camp this year I explore some of the differences between schema design for a relational database and schema design for MongoDB. You can copy and paste the commands below directly onto the MongoDB command line to follow along. To begin with, it’s important to know how to get help and see what databases and collections are available.......

I put this presentation together for a local web developer meetup. The topic was MongoDB. MongoDB is a database, but unlike traditional relational databases which store data in well defined tables (schema), MongoDB stores data in JSON like documents (BSON). This provides a great deal of flexibility. After you get through this presentation, go have a look at my hands on introduction to MongoDB and my walk through of MongoDB backups using Replica Sets.
