title: MongoDB Stored Procedure Equivalent
body: <p>I have a large CSV file containing a list of stores, in which one of the field is ZipCode.
  I have a separate MongoDB database called ZipCodes, which stores the latitude and longitude for any given zip code.</p>
  
  <p>In SQL Server, I would execute a stored procedure called InsertStore which would do a look up on the ZipCodes table to get corresponding latitude and longitude and insert the data into the Stores table.</p>
  
  <p>Is there something similar to the concept of stored procedures in MongoDB for this?
  Basically, for each insert I need to look up the latitude and longitude for that store and save that as well.</p>
  
  <p>I am not too familiar with the concept of Map/Reduce, but would that be relevant here?
  Thank you!</p>
