Part 3: Replication, Archiving and the Canonical Data Model, with 9 Practice Questions

Part 3 of the DAMA-CDMP series. This lesson covers three topics from Data Integration and Interoperability in DMBOK2: replication, archiving, and the enterprise message format (canonical data model). Every term is labeled by what it is: a method, a design pattern, a data model, or a tool. We follow one online store as it grows. What you will learn: Replication: exact copies in multiple locations, why it reads the change log, and when it is not optimal Staging area: why a non-exact target needs one Archiving: moving rarely used data to cheaper storage, retention policy, and the risk of unreadable archives Canonical data model: the problem, the solution, hub-and-spoke vs point-to-point, and when it is justified (more than 3 systems, critical above 100) Example tools: PostgreSQL, MySQL, SQL Server Always On, Oracle Data Guard, Amazon RDS read replicas, AWS S3 Glacier, Azure Archive Storage, MuleSoft, IBM Integration Bus 9 practice questions with explained answers Chapters 0:00 Introduction 0:34 The big picture 1:08 What is replication 1:43 How replication works 2:17 Benefits and tools 3:03 Exact copies and the staging area 3:42 When replication is not optimal 4:16 Replication example: the read replica 4:45 What is archiving 5:21 How archiving is done 5:56 The archive risk 6:27 The canonical data model 7:24 Hub-and-spoke by the numbers 8:02 When is a canonical model justified 8:33 Putting it together 9:11 Summary 9:46 Practice questions 10:00 Question 1 10:57 Question 2 11:48 Question 3 12:31 Question 4 13:19 Question 5 13:59 Question 6 14:40 Question 7 15:26 Question 8 16:12 Question 9 Disclaimer: This is an independent educational summary.
