The ADO Data Definition Language and Security Model (ADOX)

Abstract

One of the reasons why the ADO object model is small compared to previous data access models is that it has no specific objects to represent a data source’s schema. This is partly explained by the fact that ADO does not assume that a data source has a schema that in any way resembles the kind of design model that a relational database might have. Instead, ADO provides a single, powerful method (OpenSchema) to allow data sources to provide whatever schema information is appropriate.
