Which approach to construct a database for use during a clinical trial?

Multidimensional databases are designed for complex data analysis and reporting, often used in data warehousing scenarios. While this structure can be beneficial for analyzing large datasets, it may not be specifically suited for the targeted data collection and management needs inherent in clinical trials, which often require a more straightforward and focused approach.

Relational databases are effective for managing structured data and establishing relationships between different data entities. However, they may not capture the unique aspects and specific requirements of clinical trial data, which often necessitate a more customized database structure to accommodate various protocols and research objectives.

Flat file databases store data in a single table format, which can simplify data storage but lacks the complexity needed for clinical trials. This approach does not support the relational aspects or the necessary data integrity checks that are crucial for ensuring accurate and reliable data throughout the trial process.
