Couchbase enables multiple types of data access, including SQL, vector search, geospatial queries, and key-value access, by combining these different types of queries into a single platform. This allows for real-world problem-solving and simplifies application development, reducing costs, latency, and complexity. Couchbase supports various operations such as full-text search, time series operations, user-defined functions, full SQL capabilities, read from real-time analytics data, automatic caching, and query data synced from mobile/edge devices. The WITT demo application demonstrates these capabilities using a React UI frontend, ASP.NET Core backend, Azure Computer Vision, and Couchbase .NET SDK.
