Step-by-step explanation:

Data Repository:

A data repository is a centralized location that stores and manages data. It can be a database or a file system that allows for easy storage, organization, and retrieval of data.

Data Dictionary:

A data dictionary is a structured collection of metadata that provides a detailed description of the data objects or entities within a database or data warehouse. It includes information such as the name, type, size, and relationships of the data elements.

Data Warehouse:

A data warehouse is a large, integrated repository of data that is used for reporting and data analysis. It combines data from different sources into a single, consistent format, making it easier to analyze and make informed decisions.

Patient Port:

A patient portal is a secure online website that gives patients convenient 24-hour access to their personal health information. It allows patients to view their medical records, schedule appointments, communicate with healthcare providers, and manage their healthcare online.
