MongoDB Atlas offers a versatile document database that allows engineering organizations to build sophisticated applications that adapt to changing customer demands and market trends. Studio 3T's SQL Migration tool simplifies the process of migrating data from legacy SQL relational databases to MongoDB Atlas, making it reliably repeatable and easier to perfect the new schema. Hackolade's schema design and data modeling tools complement Studio 3T by allowing developers to design their migration first, visually reassemble the SQL fields to compose the MongoDB document schema, and then implement with confidence. The combination of these tools enables complex migrations to be performed easily, without requiring team-breaking chores, making it possible to perfect the new schema as often as needed.
