What term refers to a system that allows for efficient data handling and analysis?

The term that best refers to a system that allows for efficient data handling and analysis is "data management." This concept encompasses a broad range of processes and systems that are designed to collect, store, organize, and maintain data in a way that makes it easily accessible and usable for analysis and decision-making. Data management involves not only the technological aspects of handling data, such as databases and software tools, but also includes considerations for data quality, data integration, and data security.

While "database management system" is specifically focused on the software tools that manage databases, and "data ecosystem" refers to the larger network of data sources and stakeholders, "data governance model" pertains to the policies, standards, and frameworks that guide how data is managed and used within an organization. Data management, on the other hand, serves as the overarching practice that includes all of these elements and emphasizes the importance of ensuring data is well-governed, yet also effectively accessible for analysis. This makes it the most comprehensive choice in the context of handling and analyzing data efficiently.
