1. Abstract
Data Lake-Based Healthcare Analytics is a data engineering and analytics system designed to collect, store, process, and analyze large volumes of healthcare data from multiple sources. It integrates electronic health records, laboratory reports, medical claims, and patient information into a centralized data lake. Using big data processing and analytics techniques, the system identifies healthcare trends, analyzes patient outcomes, and generates interactive reports. It supports data-driven decision-making while improving healthcare data accessibility and operational efficiency.
2. Objectives
- To integrate healthcare data from multiple sources.
- To store structured, semi-structured, and unstructured data.
- To process large healthcare datasets efficiently.
- To identify patient care and healthcare service trends.
- To generate interactive analytics dashboards.
- To support healthcare planning and operational decisions.
3. Existing System
Traditional healthcare systems store information in separate databases, hospital systems, spreadsheets, and medical record platforms. Integrating these sources for comprehensive analysis can be difficult.
Disadvantages:
- Healthcare data is distributed across different systems.
- Limited integration between data sources.
- Difficulty processing large datasets.
- Time-consuming report generation.
- Challenges analyzing historical healthcare trends.
4. Proposed System
The proposed system uses a data lake architecture to store healthcare data in its original format and process it for analytics. Data ingestion pipelines collect information from authorized healthcare datasets, databases, and files. Processing tools clean and transform the data, while analytics modules calculate healthcare indicators such as patient demographics, admission rates, treatment outcomes, and hospital resource utilization. An interactive dashboard presents trends and reports to authorized users.
Key Features:
- Healthcare data ingestion.
- Centralized data lake storage.
- Structured and unstructured data processing.
- Patient and hospital analytics.
- Data quality monitoring.
- Interactive healthcare dashboards.
- Role-based access control.
- Secure data handling and audit logs.
