Research Data Management

Good research starts with good data. This guide will help you understand how to organize, store, protect, and share your data throughout your research journey.

What is Data Processing?

Data processing in research data management involves the systematic transformation, cleaning, analysis, and preparation of raw research data to make it suitable for analysis and interpretation. It's a critical component that bridges the gap between data collection and meaningful research outcomes, ensuring data quality, integrity, and usability throughout the research lifecycle

Data Processing Lifecycle

The Data Processing Lifecycle outlines the essential steps for managing and preparing research data for analysis and reuse. This structured approach ensures that data remains accurate, consistent, and meaningful throughout the research process.

1

Data Collection & Ingestion

Gathering raw data from various sources, for example, through experiments, surveys, sensors, databases, data collection APIs, etc.

Surveys Experiments Sensors APIs
2

Data Cleaning & Validation

Identifying and correcting errors, inconsistencies, and missing values to ensure data quality and reliability.

Remove duplicates
Handle missing values
Standardize formats
Validate ranges
3

Data Transformation & Integration

Converting data into suitable formats and combining multiple data sources for comprehensive analysis.

4

Analysis & Modeling

Applying statistical methods, machine learning algorithms, and analytical techniques to extract insights.

5

Documentation & Preservation

Creating comprehensive metadata, documentation, and ensuring long-term preservation of processed data.

Key Processing Techniques

Research data often comes in diverse forms — numbers, text, images, maps, and signals. Each type requires specific processing techniques to extract meaningful insights. By leveraging appropriate tools and methodologies, researchers can ensure the quality, reusability, and interpretability of their data throughout the research lifecycle.
