Merge |
|
The Data Dictionary Merge utility allows table definitions to be merged from one set of dictionary files (providex.ddf/.dde) to another.
Processing a merge involves defining a merge option to deal with cases where the table being merged already exists in the destination dictionary files. You can select an option to replace the contents of the table definition in the destination file, merge the contents of the source and destination files (with the source definition taking precedence), or skip the table.
Invoke the Data Dictionary Merge utility by selecting Utilities > Merge from the Data Dictionary Maintenance menu bar.
This utility consists of the following:
|
Dictionary Source File |
Path to the dictionary source file. |
|
Dictionary Destination File |
Path to the dictionary destination file. |
|
Tables |
Lists the dictionary tables displayed by file groupings in a tree view format. Clicking on a particular table will cycle through the options for dealing with duplicate tables. Clicking on a file group will cascade the setting for the group to its associated tables. Clicking on the source path at the top of the tree will select for the entire tree. |
|
Table Details |
Displays the element descriptions and indexes for a selected table. |
