The Global Data command allows the management of databases of information that may be referenced from individual nodes or links. This reduces data redundancy dramatically and associated problems of updating at many places when changes are made. The Global Database records for RDII can now be both imported and exported using the Import/Export External Databases wizard. Previously only import was supported but now we can have records both imported and exported allowing changes in XP to easily go back to a referenced geodatabase or other tabular source.
This page contains the following topics:
General Information
Each global Database Type relates to a grouping of related data items. There can be any number of database records for each database type.
Each database record has a name, which will be referenced from a node or link dialog (or Job Control), and a description. Hitting the EDIT button causes the dialog containing the data for the highlighted Database Type and database Record Name to be displayed.
- (R) – Runoff Mode, (S) – Sanitary Mode (H) – Hydraulics Mode
- For XPSWMM/XPStorm 2015, the Global Database records for RDII can now be both imported and exported using the Import/Export External Databases wizard. Previously only import was supported; with the 2015 release, users now have the option to export RDII records, allowing changes in xp to easily go back to a referenced geodatabase or other tabular source.
Global Database Selection
Global Database records are selected from a data dialogue associated with a node or link. For a field corresponding to one database type, when you click on the selection button you will be presented with a list of all currently available global database records.
In the example shown below, in the data dialogue for Sub-catchment #1 of Node MH1, clicking on the selection button for Rainfall opens the Rainfall Global Data selection. Clicking on the selection button for Infiltration opens the Infiltration Global Data selection.
The Database Type shown in the selection list box will depend on the context of the parent node or link.
Select Will select the currently highlighted record and display this name in the selection button of the parent (calling) dialog.
Cancel Will cancel the selection and leave the selection button of the parent (calling) dialog unchanged.
Edit Will allow you to edit the information for this record of the Database Type shown. All nodes referencing this database record will inherit the edited data.
Clear will clear the database record name shown in the selection button of the parent (calling) dialog.
Rename will rename the highlighted database record however all nodes referencing the existing database record will have an undefined reference and will generate an error on solving if not individually updated.
Delete will delete the highlighted database record and all nodes referencing the existing database record will have an undefined reference and will generate an error on solving.
Duplicate will create a copy of the highlighted database record with the existing name plus a .1, .2 etc suffix.
Add will create a new database record of the name shown in the edit field below the record name listbox.
Database Types
Several types of database records are available; these are displayed in the left-hand side scrollable list below this heading. As each database type is selected, the list of available records in that database is displayed in the list to the right. This list is created and maintained by the user. The list to which keystrokes, such as arrow keys, <page-up>, <page-down>, <home>, <end>, <insert>, <delete>, etc. will be directed is highlighted with a bounding rectangle. Either list can be made the active list by clicking in it.
The available database types are described briefly below. (R) denotes a database used by the Runoff layer, (S) denotes a database used by the Sanitary layer and (H) denotes a database used by the Hydraulics layer.

| User Hazard Values | Additional User input for Hazard Variables (i.e. debris factor, etc.) |
Record Name
This scrollable list displays the available records from the current Database Type. This list is manipulated by the buttons on the right-hand side of the list. You can add, delete, rename, and duplicate records to this list using these buttons. This list can be navigated in the same way as the database type list, ie. arrow keys, <page-up>, <page-down>, etc.
The edit item immediately below the Record Name List contains the name of the currently highlighted database record. Edit this item before adding or renaming a database record. This name will be used when the database record is referenced from an Object or Job Control dialog.
Description
Description of the database record. This item may be any meaningful description of the current database record of the current database type. This field is for annotation, it is not used by the model.
Duplicate Record
Hit this button to duplicate the highlighted database record. This facility has not yet been implemented.
Rename Record
Hit this button to rename the currently highlighted database record with the name entered. The command is executed when OK is hit or another database type is selected.
Edit Record
Hit this button to edit the data for the currently highlighted database record. This button may sometimes be inactive (greyed out), which indicates that, in the current context, editing of the currently highlighted database type is not available. The following table indicates the conditions required to make editing available for each database type.
