Why use Reschema?

With a powerful MongoDB migration tool, a schema makeover is only a few clicks away

Clean up SQL migrations

Just migrated data from SQL to MongoDB? Restructure your newly imported tables and columns as MongoDB documents that make the most sense.

Merge multiple sources easily

Reschema lets you merge data from multiple collections into one source collection, so you can start with the data you need without having to write a single $lookup.

Update schema – minus the migration scripts

MongoDB is great for ad-hoc schema changes, but these could get unruly over time. With Reschema, you can easily restructure collections to reflect changes in your data. Like pressing a handy reset button.

Improve performance by skipping unnecessary schema or document versions

MongoDB lets you keep multiple versions of your schema or document, but this means duplicating indexes. Keep collections light and simple with a schema cleanup instead.

Studio 3T has best user interface that I have ever seen in database software. We love the built-in aggregate and map-reduce functions. We build complex queries with these functions very quickly. So I know this is the "must-have" software for MongoDB developers. /
