Section 2.1 provides a brief review of relational databases. Section 2.2 introduces background concepts on spatial databases and presents conceptual and logical models for spatial database design. We discuss implementation considerations for spatial data focusing in PostGIS, the spatial extension of PostgreSQL, and address spatial queries expressed in SQL. Section 2.3 addresses temporal databases, also introducing a conceptual model and a relational implementation that is queried using SQL. Together, spatial and temporal databases are the building blocks of mobility databases, introduced in Sect. 2.4, where we also give example queries expressed in MobilityDB.

摘要

Section 2.1 provides a brief review of relational databases. Section 2.2 introduces background concepts on spatial databases and presents conceptual and logical models for spatial database design. We discuss implementation considerations for spatial data focusing in PostGIS, the spatial extension of PostgreSQL, and address spatial queries expressed in SQL. Section 2.3 addresses temporal databases, also introducing a conceptual model and a relational implementation that is queried using SQL. Together, spatial and temporal databases are the building blocks of mobility databases, introduced in Sect. 2.4, where we also give example queries expressed in MobilityDB.
