I have a custom mongo database, that database contains information about pages.I need to query it in order to use SEP to create pages according to that info, ig, adding renderings component, etc. That mongo collection has info required to see what component rendering I should use, also it has the data of the page to be created. So I have to query that mongodb from Powershell, the according to that data create an item. Can I 'atached' that mongo database to sitecore, and from SEP query the mongodb? I dont seem to find any documentation on how to do so, using mongodb.
