This Schema is used to validate the DVM Document got for dvm files are based on the schema definition (XSD) file shown in the following example:Įach column in the same order as defined in Columns. As shown in Figure 44-1, the lookup mechanism sets the higher order qualifier State to the exact lookup value Arkansas and uses Canada|"" for the lower order qualifier Country.įigure 44-3 A Domain Value Map File in Applications Windowĭescription of "Figure 44-3 A Domain Value Map File in Applications Window"Īll. In this example, the State qualifier has a qualifier order of 1 and the Country qualifier has a qualifier order of 2. State=Arkansas, Country=Canada, Cit圜ode=KN_USA Figure 44-1 describes the steps of a hierarchical lookup performed for the following lookup (based on the values in Table 44-3): It proceeds until a match is found, or until a the lookup is exhausted and no match is found. If you specify a qualifier value during a lookup and no exact match is found, then the lookup mechanism tries to find a more generalized match by setting the higher order qualifiers to empty quotes ( ""). In Table 44-3, the state qualifier is probably given a higher order than the country qualifier because a matching state indicates a more precise match.ĭomain value maps support hierarchical lookup. The order of a qualifier varies from highest to lowest depending on the role of the qualifier in defining a more exact match. When there are multiple qualifier domains, you can specify a qualifier order to indicate how they are used during runtime lookups. Table 44-1 shows a point-to-point mapping for cities between two domains: For example, you might have one domain value map that defines city name mapping, one that defines state name mapping, and one that defines country name mapping.Ī direct mapping of values between two or more domains is known as point-to-point mapping. Thus, one SOA composite might contain several domain value maps. While each domain value map typically defines the mapping for only one field or category, a single SOA composite can require mappings for multiple categories. Domain value maps operate on the actual data values in the messages that are transmitted through an application at runtime. Rather than requiring each domain to standardize their data to one set of terminology, you can use domain value maps to map the terms used in one domain to the terms used in other domains. For example, one domain might use complete city names in its messages ( Boston), while another domain uses a code to indicate the city ( BO). When information is transmitted between different domains, each domain might use different terminology or processing codes to describe the same entity.
