Abstract: Systems and methods described herein may improve data migration between databases that store data under different schemas. Such systems and methods may be used to transform data from a first schema (e.g., tabular, such as in relational databases) to second schema (e.g., document-based, such as in some non-relational databases). In some embodiments, data transformation for database migration may be performed using at least one rule (e.g., specified by a user) specifying a logical arrangement under the second schema for transforming a grouping of source data under the first schema. For example, tables under a tabular schema may be transformed into new documents and/or fields within documents under a document-based schema in a manner specified by the transform rule(s). In some embodiments, transforming source data in this manner permits organizing the migrated data efficiently to reduce computing resources needed to migrate the data between databases and/or for future data access operations.
