7.5.2 Proprietary versions of XML specifications

Database vendors that create proprietary versions of XML specifications tend to be pretty up-front about it. Even to the extent of creating new acronyms for their unique implementations. Building on vendor-driven standards may be a better solution than providing non-XML-based extensions altogether, but it will still tie you to a product platform.

7.5.3 Proprietary XML-to-database mapping

Some databases provide data mapping facilities that allow you to associate XML documents to existing relational data models. Data maps can be generated through either a front-end tool or a programmatic API.

Regardless of how they are accessed, proprietary data maps will restrict you to the interface of the tool or API, which can often be quite limited. Additionally, a common problem here is that the map itself is stored in a proprietary format. This creates further dependencies between your architecture and a single database platform.

It is much more desirable for a mapping tool to generate its output into XML standard syntax, such as XSD schema and XSLT files. This will allow you to migrate the data maps to another product, and also gives you the freedom of editing them yourself.
