There are three ways to create a new DOM in M/DB:X
See the DOM API Reference for details
Each document that is successfully created is given two unique identifiers:
When referencing documents you may use either of these identifiers. All Actions that require a document to be specified can use either of these identifiers.
When a document (aka DOM) is created in M/DB:X you can do any of the following:
The DOM API Reference provides details on the Actions to carry out these operations.
The number of documents you store is limited only by the disk storage available to the underlying GT.M database and Virtual Appliance. As a rule of thumb, a DOM representation of an XML document occupies between 5 and 10 times more storage as the original XML held in a text file, due to the pointers and indexes that form the DOM structure.
You can list your DOMs using the ListDOMs Action.
To delete DOMs, use the DeleteDOM, DeleteDOMsByPrefix or DeleteAllDOMs Actions
There's otherwise almost no administration involved in running and supporting an M/DB:X installation!
M/DB:X runs as an application on top of the GT.M database. GT.M provides a comprehensive set of system management functions including backup and restore, database replication, journalling etc, as you would expect from a database technology with a long pedigree in the highly demanding banking sector. If you're using the M/DB Virtual Appliance, you'll find a link to the GT.M Administration and Operations Guide which describes the relevant facilities.
The DOMs created and managed by M/DB:X reside in a single global: ^zewdDOM If you are using the M/DB Virtual Appliance, this global resides in the GT.M database in the /usr/local/gtm/ewd path.
