All navigation data in an NDS database belongs a specific building block. Each building block addresses specific functional aspects of navigation, such as names for ___location input, routing, or map display. To cover specific use cases, navigation systems and applications may be required to filter and aggregate data from different building blocks, e.g. from both Routing and Map Display in order to calculate a route and show it to the user.

Each update region may contain data from multiple building blocks. Within a product database, which has several update regions, there may thus be several instances of the same building block. Example: In a Europe product database, there may be a Basic Map Display building block in the update region “France” and a Basic Map Display building block in the update region “Germany”.
