Oracle Corporation acquired GoldenGate in 2009 as part of future strategy to implement advanced

replication technologies within the product suite of data warehousing and real-time transaction

management. Before the advent of Oracle GoldenGate technology, data replication was performed using

Oracle Streams and third-party replication solutions such as Quest SharePlex. This chapter discusses

various types of database replication methods along with the techniques used by each method, to

illustrate how Oracle GoldenGate came to be the logical conclusion for the current and future real-time-

based data-transaction replication technology with Oracle database systems.
