– In a database model that supports a three-schema architecture (such as that described by ANSI/X3/SPARC), a description of the information contents and structure of a database. A conceptual schema provides a model of the total database, thus acting as an intermediary between the two other types of schemas (internal and external) that deal with storing information and presenting it to the user. ¹

– In the Data Warehouse a conceptual model that maps to the data in the physical store and provides an understandable view of the data. When a developer creates code to access or change data in the Data Warehouse the developer interacts with the logical schema. Commerce Server processes data in the Data Warehouse through the logical schema. ¹
