Data Governance & Database Design
1. As HIM director of a healthcare system, you have been appointed to a team of individuals to develop a rationale for a Data Governance (DG) program. In one of the first team meetings the agenda is to discuss and develop a list of key factors for DG program success and explain why each is critical for achieving a viable DG program.
a. Create the supporting document that will be presented at an Executive meeting to help the CEO and other executives decide about how to structure the DG program. (25 points)
2. Many hospitals need to track trends about patient outcomes to improve healthcare delivery. However, they often lack the tools necessary to achieve that goal. At University Hospital, the database management systems (DBMS) administrator is responsible for creating and maintaining databases. Several departments have asked him to develop real-time analytics and visualizations to track patient trends. These real-time analytics and visualizations would be based on standard simple queries. They also want to keep track of all the data they document and have had trouble creating a system that is modeled well for easy access.
a. Evaluate if the DBMS administrator should choose a NoSQL database or a relational database for real-time analytics and visualization? Data Governance & Database Design
b. For the system the database administrator must build to track all the data University Hospital documents, what are the database design steps the database administrator should follow to ensure the information is organized and stored for easy access? Please describe each step.

Comprehensive Answers
1. Key Factors for Data Governance (DG) Program Success and Importance
A successful Data Governance program relies on several critical factors:
-
Executive Leadership and Sponsorship – Top-level support ensures the DG program has the authority, funding, and visibility to drive compliance across all departments.
-
Defined Roles and Responsibilities – Clearly establishing who owns, manages, and uses data reduces confusion and maintains accountability for data integrity.
-
Data Quality Management – Ensuring accuracy, completeness, and consistency of data enables better decision-making and reduces errors in reporting.
-
Policies, Standards, and Procedures – Documented guidelines establish how data is created, stored, accessed, and protected, ensuring uniformity across systems.
-
Education and Training – Staff understanding of DG principles promotes adherence to policies and helps build a data-driven culture.
-
Technology Infrastructure – The right tools for data integration, metadata management, and monitoring enable scalability and automation of DG processes.
-
Performance Metrics – Ongoing measurement and reporting on data quality and governance effectiveness allow for continuous improvement.
Each factor ensures data remains accurate, secure, and usable, creating a foundation for organizational trust and informed decision-making.
2. Supporting Document for Executive Meeting
Purpose:
To present a rationale and framework for implementing a structured Data Governance (DG) program.
Key Components:
-
Executive Summary: Outlines the importance of DG for data quality, compliance, and strategic decision-making.
-
Program Vision: Establishes goals such as data integrity, security, and value-driven use of data assets.
-
Organizational Structure: Defines a DG Council led by the HIM Director, including data stewards, compliance officers, and IT specialists.
-
Implementation Plan: Stages include assessment, policy development, training, and monitoring.
-
Expected Outcomes: Improved data reliability, streamlined workflows, regulatory compliance, and enhanced patient care outcomes.
This document will guide the CEO and leadership in adopting a sustainable DG framework aligned with the healthcare system’s strategic goals.
3. Choice Between NoSQL and Relational Database
For real-time analytics and visualization, a NoSQL database is generally more suitable.
-
Advantages of NoSQL:
-
Handles large, unstructured, and rapidly changing datasets efficiently.
-
Provides flexibility for various data formats (text, images, sensor data).
-
Offers high scalability and faster read/write operations for real-time analytics.
-
Supports horizontal scaling across multiple servers.
-
In contrast, a relational database is ideal for structured data and strong consistency but may struggle with scalability and speed in real-time scenarios. Therefore, for dynamic dashboards and analytics on patient trends, NoSQL databases like MongoDB or Cassandra are preferred.
4. Database Design Steps to Track All Hospital Data
The database administrator should follow a structured approach to ensure organized, accessible, and reliable data management:
-
Requirements Analysis: Identify what data needs to be stored, who will use it, and how it will be accessed.
-
Conceptual Design: Develop an entity-relationship diagram (ERD) to visualize relationships among data entities.
-
Logical Design: Define tables, keys, attributes, and normalization rules to ensure minimal redundancy and consistency.
-
Physical Design: Decide on storage structures, indexes, and data types for optimal performance.
-
Implementation: Create the database schema using chosen DBMS tools and populate it with test data.
-
Testing and Validation: Verify data accuracy, performance, and security; adjust indexing or structure as needed.
-
Maintenance: Regularly monitor performance, back up data, and update schema as organizational needs evolve.
