My Answer:
A data lake is a storage repository that holds a vast amount of raw data in its native format until needed, whereas a data warehouse is a system used for reporting and data analysis that is structured and processed.

Data Lake Data Warehouse
Stores raw, unprocessed data Stores structured, processed data
Schema-on-read (defined when data is used) Schema-on-write (defined when data is stored)
Ideal for big data and machine learning Optimized for SQL queries and BI applications
Can handle a variety of data types (structured, semi-structured, unstructured) Primarily deals with structured data
More flexible, but requires more processing power Less flexible, but highly optimized for its purposes

Data lakes are generally used when there is a need to store all data without a clear purpose in mind yet, while data warehouses are used when the main goal is to perform complex queries and analysis on processed data.

Metadata in data architecture is critical for a variety of reasons:

  • Data Understanding: Metadata provides information about data, which helps in understanding its meaning, origin, and usage.
  • Data Management: It aids in the governance, classification, and organization of data.
  • Interoperability: Metadata ensures that different systems and applications can effectively share data.
  • Compliance: It helps in meeting regulatory requirements by tracking the lineage and history of data.

Metadata should be well-defined, consistent, and integrated into the data architecture to maximize its effectiveness.

15. How do you approach data redundancy and disaster recovery? (Disaster Recovery)

Preparing for data redundancy and disaster recovery is crucial for maintaining data integrity and availability. My approach includes:

  • Regular Backups: Ensuring data is backed up at regular intervals, and backups are tested frequently.
  • Replication: Implementing data replication strategies across different geographic locations to prevent data loss due to site-specific disasters.
  • Failover Mechanisms: Configuring failover mechanisms to allow for quick recovery in the event of a failure.
  • Disaster Recovery Plan: Developing a comprehensive disaster recovery plan that outlines the procedures to restore data and services in the event of a disaster.

Here is a table outlining disaster recovery strategies:

Strategy Description Use Case
Backup and Restore Regular backups are taken and can be restored when needed. Most non-critical data that doesn’t require immediate availability.
Pilot Light A minimal version of the environment is always running in the cloud. Critical applications where recovery time needs to be short but not instant.
Warm Standby A scaled-down but fully functional version of the environment is always running. High-priority applications where downtime needs to be minimal.
Multi-Site The full environment is duplicated and runs concurrently across multiple sites. Business-critical operations that require immediate failover with zero downtime.

Implementing these strategies ensures data is protected and the organization can resume normal operations quickly after any data loss incident.
