How to use N1QL to migrate Oracle data into Couchbase

Migrating a relational database to Couchbase involves downloading the Couchbase server, using connectors or export-import tools, and considering key differences between RDBMS tables and Couchbase buckets, including document keys and schema transformation. The blog outlines strategies for transforming relational schema into Couchbase's NoSQL JSON format, such as direct mapping, denormalization, and adding child records as array fields. It emphasizes using Oracle's REST Data Services for data extraction and N1QL scripts for the transformation process, highlighting the importance of managing primary keys and document types. The document also notes the limitation of N1QL CURL() in handling large data volumes and suggests using Oracle's OFFSET and FETCH clauses for batch processing, while a comment advises using scripting languages for large migrations.
