GenAI & Architecture Design

Objectives

Use generative AI to create an efficient data architecture design for the following scenarios:

  • Healthcare industry (EHR System):

    Centralize patient information from various sources, strict data security, and robust analytics for clinical decision-making.

  • Retail industry (CRM System):

    Consolidate customer data for personalized marketing, prioritize data security, and implement analytics for segmentation and recommendations.

EHR

A hospital network is implementing an electronic health records (EHR) system to centralize patient information, streamline medical records management, and improve patient care delivery. The data engineering team has developed the following considerations for the data architecture design.

  1. Integration of data from various sources such as patient registration systems, laboratory systems, imaging systems, and medical devices.

  2. Utilization of a secure and scalable data storage solution to store sensitive patient information.

  3. Designing a comprehensive data model to represent patient demographics, medical history, diagnoses, treatments, and prescriptions.

  4. Implementing strict data governance policies to ensure patient privacy, data security, regulatory compliance, and data quality standards.

  5. Implementing robust access controls, encryption, and auditing mechanisms to protect patient data from unauthorized access or breaches.

Solution

You may use the generative AI lab to incorporate these considerations to propose a detailed data architecture design plan. However, giving too much information to the model simultaneously might result in a biased response. So first, run the following prompt and check the response.
