I am totally new to MongoDB and currently investigating to what extend I can make use of the database structure while I have mostly been working with RDBMS until now.
First try was an import of an example data set (CSV) from https://www.kaggle.com/nickhould/craft-cans/data via the MongoDB Compass Community edition under Windows.
The data set consists of two CSV files to import. So I created a new database with two collections trying to upload the CSV files to one collection each.
The CSV already contains IDs which is why I selected at the importing dialog at the first selectable column “ObjectID” instead of “String”. Unfortunately after confirming the selection with hitting the import button, the screen stays totally blank. Just the top menu bar remains visible but nothing else. This behaviour happens every time again while when keeping the columns data type to “String” everything works fine.
Can someone please explain this behaviour and let me please know why the data cannot be linked to each other?
