The Data Exchange/Marketplace solution enables data ingestion, exposure, and entitlement across third-party data sources and users. The platform acts as a data marketplace that connects data publishers and data consumers who seek to deploy data-driven solutions. Data publishers are public or private sector organizations wanting to share data within their organizations or with others.

Data consumers are end-users (may include data publishers) that access the data to deliver solutions and services. The data can be monetized or shared freely.

The client’s data-sharing solution includes several PostgreSQL databases used for various purposes including internal accounting, microservice metadata, metrics derived from data sources, and information from sensors deployed in road infrastructure. The team utilizes the PaaS PostgreSQL service on Azure.
