Couchbase Server is one of the leading NoSQL databases in the document store type databases category. Couchbase stores documents using the JSON data format, which is the most flexible of data models with provision to create hierarchies of data structures. In contrast, Oracle database stores data in a fixed schema table format. The database model of Couchbase is based on Document store while in Oracle Database data is organized as tables with two-dimensional matrices made of columns and rows. In this chapter we shall migrate an Oracle Database table to Couchbase Server. A direct migration tool is not available for migrating from Oracle to Couchbase. We shall first export Oracle Database table to a CSV file. Subsequently we shall import the CSV file data into Couchbase Server using the cbtransfer tool. This chapter covers the following topics.
