XML Storage and Indexing Native XML
Indexing Native XML
The architectures of native XML databases fall into twobroad categories: text-based and model-based.
In this section, a number of the features found in native XML databases will briefly be introduced.
For many people, especially those with relational database backgrounds, native XML databases raise a number of controversial issues, particularly with respect to issues surrounding the storage of data. These are:
Coercion function: denoted as t1→t2 represents, in a particular database, a data type t1 can be converted to the data type t2.
Recursively, the subpattern isthen used to search children of selected node. When traversal of Patricia trie reachesa leaf node, the search pattern must be compared with the original string referredby the leaf node. This is required because of the lossy compression of the commonparts.
- Containment property - Direct containment property
- Tight containment property - Proximity property
We will just give an example of direct containment property and not go into more detail.
