The text explores the process of data movement in integration projects, focusing on the use of Couchbase's N1QL language for transforming and manipulating data. It contrasts the traditional ETL (Extract-Transform-Load) with the ELT (Extract-Load-Transform) approach, emphasizing a practical ELT example using Oracle Database and Couchbase. Initially, data from an Oracle HR schema is exported and loaded into Couchbase as JSON documents, followed by a transformation process that involves denormalizing data for performance optimization. This involves embedding referenced data directly within documents to reduce database interactions, such as combining location, country, and region data into a single document and embedding job history into employee documents. The process employs N1QL for creating and managing data in two Couchbase buckets, demonstrating the creation of primary indexes and use of SQL-like queries for inserting and updating documents. The example concludes with the deletion of temporary documents and reinsertion of original job data, illustrating N1QL's capabilities in efficient data manipulation.
