You can use namespace and data queries with most connectors. You use namespace queries to provide a list of names and realize a connector's functionality and the data values available from a specific server. You use data queries to return data from the connector.
You can combine a namespace query with advanced HTML and JavaScript to create an interactive form with the results of the query. A mode that ends in "List" is a namespace query and returns a list box. Namespace queries are used in the SAP MII templates and with the ad-hoc data browsing dialogs in the SAP MII applets. Examples of namespace query modes include the following:
ServerList
GroupList
TagList
TableList
ColumnList
ModeList
TimePeriodList
KPIList
Some connectors provide a legend describing the data items returned by the data query. Examples of data query modes include the following:
History
HistoryEvent
Current
Statistics
Query
FixedQuery
Command
AlarmHistory
AlarmSummary
AlarmStatistics
