If you want a quick (but kinda dirty) way to import your SQL Server database to MongoDB, this is your tool.
MongoDB SQL Server Importer (Sql2Mongo) is for those who wants to leverage their existing database to learn MongoDB. It's developed in C#.
Note from the Developer
I don't recommend straight away converting your RDBMS into MongoDb or any other ODBMS. Converting from RDBMS to ODBMS requires careful thought as relational concepts may not apply.
Sql2Mongo.exe <SQL Server Connection String> <MongoDB Connection String>
MongolSqlImport "Data Source=(local);Initial Catalog=AdventureWorks2008;Integrated Security=True" "mongodb://localhost:27017"
- Non-Mongo compatible types are converted into String datatypes
