In this comprehensive analysis, we will explore the essential skills and knowledge areas that are paramount for anyone aspiring to excel in this field.

1. Technical Expertise:

The backbone of data warehouses is their technical infrastructure. Managers must have a firm grasp on database management systems, ETL (Extract, Transform, Load) processes, data modelling, and querying languages such as SQL. Knowledge of big data technologies like Hadoop, Spark, or cloud solutions such as AWS Redshift, Google BigQuery, and Azure, is increasingly important. Additionally, understanding the principles of data integration and familiarity with BI (Business Intelligence) tools are must-have skills.

2. Analytical Skills:

Interpreting data to draw meaningful insights is at the core of a Data Warehouse Manager's role. This requires strong analytical skills to navigate data trends, performance metrics, and effectively communicate findings to stakeholders. Being comfortable with statistical methods and having a mindset that questions and probes the data for deeper understanding will set apart competent managers in the field.

3. Strategy and Planning:

Strategic planning is necessary to align the data warehouse with the business objectives. This means being able to map out a long-term data strategy, including the infrastructure needed, methodologies to employ, compliance with data governance standards, and future scalability. It is also about understanding the landscape of industry-specific data needs and how they can be catered to through the data warehouse.

4. Leadership and Project Management:

Data Warehouse Managers must possess leadership qualities to lead a team of data professionals. They need to exhibit skills in project management, resource allocation, setting timelines, and delivering results. Having a PMP (Project Management Professional) certification or experience with Agile methodologies can be valuable in fulfilling these roles effectively.

5. Communication and Interpersonal Skills:

The ability to communicate complex technical concepts in simple terms to non-technical stakeholders is invaluable. Strong interpersonal skills help in liaising with various departments, managing team dynamics, and fostering a collaborative work environment. Negotiation skills and the ability to influence are also critical when it comes to advocating for resources or changes in processes.

Data Warehouse Managers must understand the implications of data protection laws such as GDPR, CCPA, and HIPAA and ensure compliance. Knowledge of security best practices and measures to protect data integrity are non-negotiable essentials.

8. Continuous Learning and Adaptability:

The landscape of data warehousing is ever-changing with new technologies emerging frequently. Staying updated with the latest trends, tools, and methodologies is crucial. An open mindset towards ongoing learning and adaptability to change can greatly enhance a manager's effectiveness.

9. Vendor and Technology Selection:

Knowing which technologies and vendors to work with is also part of managing a data warehouse. Managers should be equipped to evaluate and choose the right tools that fit their organizational needs and budgets.

10. Financial Acumen:

Understanding the cost implications of data warehouse operations is important for budgeting and financial planning. Managers should possess the financial literacy to make cost-effective decisions without compromising on the quality of services.

In conclusion, the role of a Data Warehouse Manager is multi-faceted, requiring a blend of technical and managerial skills.
