User
interface Data Models (UDMs) |
|
The
User Data Model (UDM) represents the relationship between an
HTML page and the data elements it retrieves/stores, in XML
form. The UDM is constructed by including data-items that come
from database and business objects. The UDM editor in the zDE helps a designer edit, extend and manipulate data retrieved
from the database or from external sources like a mainframe
database or an ERP system. |

Types
of UDM |
|
Auto-generated UDMs
|
|
zeroCode
automatically creates UDMs for common table operations - list,
add, search, view, browse by foreign key |
|
Such
UDMs are generated for all tables, unless otherwise specified
in the generator pages |
|
Multi-table
requirements are not addressed by auto-generated UDMs, but can
be easily created as custom UDMs. |
|
Auto
UDMs can be extended via filters and regeneration of HTML. |
|
|
|
Custom UDMs
|
|
Custom
UDMs typically span multiple tables / data sources or are Relators |
|
zeroCode
automatically determines table relationships in the UDM Editor |
|
Custom
UDMs use a Custom meta-template that can be enhanced |
|
Custom
UDMs can be directed to exit to an internal page or to a page
outside the site. |
