Week 1 Task: Data Migration Strategy:

The first week will focus on planning and strategy in data engineering. Your task is to develop a comprehensive data migration strategy for a hypothetical organization. This organization intends to move its on-premise data to a cloud-based solution. Your DOC file should include: 1) An overview of your proposed strategy, 2) Detailed steps on how you intend to execute the migration, 3) A risk assessment and mitigation plan, and 4) A timeline for the migration. Key evaluation criteria will include the comprehensiveness of your strategy, the feasibility of your proposed execution steps, and the robustness of your risk assessment and mitigation plan. This task should take approximately 30 to 35 hours to complete and does not require any specific datasets or resources beyond those available publicly.

Week 2 Task: Database Design and Optimization:

The second week focuses on execution, specifically in the area of database design and optimization. Your task is to design an optimized database schema for a hypothetical e-commerce company with millions of users. Your DOC file should include: 1) An overview of the database design, 2) Proposed tables, fields, relationships between tables, and indexing strategy, 3) Documentation of the SQL statements to create and optimize the database schema, and 4) A brief explanation of why your design is optimized for performance. Key evaluation criteria will include the appropriateness of your design for the e-commerce context, the accuracy of your SQL statements, and the soundness of your performance optimization strategy.

Week 3 Task: Data Governance Policy:

The third week focuses on policy and governance, a crucial aspect of a Data Engineer's role. Your task is to draft a data governance policy for a hypothetical healthcare organization. Your DOC file should include: 1) An introduction explaining the importance of data governance, 2) Detailed sections on data quality, data security, data privacy, and data lifecycle management, and 3) A conclusion summarizing the policy.
