Hive Metadata vs Master Data: Differences Explained

Hive metadata and master data are distinct concepts that play different roles in data management.

1. Metadata in Hive:
   Hive serves as a data warehouse system for storing and querying large datasets. Hive metadata refers to the information describing the data and table structures within Hive, including table names, field names, data types, partitions, etc. This metadata is essential for managing and querying data, helping users to understand the structure and properties of the data.
2. Core Data:
   Core Data refers to the key data widely used and shared within an organization, including customer information, product information, employee information, etc. It is the most important data in an organization, typically shared and utilized by multiple application systems. Data management involves managing and maintaining core data to ensure consistency, accuracy, and completeness.

Therefore, Hive metadata and master data are separate concepts used to manage data within a data warehouse and core data within an organization, respectively. In data management, master data management and Hive metadata management are typically different workflows.
