Reverse Engineering Options for Teradata

Following are the reverse engineering options for Teradata.

Overview

Parameter

Description

Additional Information

Reverse Engineer From

Specifies whether you want to reverse engineer from a script or database

Database: Indicates that the model is reverse engineered from database

Script File: Indicates that the model is reverse engineered from a script

File

Specifies the script file's location

This option is available only when the Script File option is selected

Option Set

Parameter

Description

Additional Information

Option Set

Specifies the option set template for reverse engineering

Open: Use this option to open a saved XML option set file.

Save: Use this option to save the configured option set.

Save As: Use this option to save an option set either in the model or in the XML format at some external location.

Delete: Use this option to delete an option set.

Specifies the objects to be reverse engineered according to the selected option set. You can edit this list.

Detailed Options

Parameter	Description	Additional Information
NSM Options	Specifies the naming standard glossary file in the .CSV format
Table Filter (comma separated)	Specifies the tables that you want to set as filter criteria. To specify multiple tables, use a comma-separated list.	For exact matches, mention table names in upper case inside double quotes(for example, "TABLE1"). To use wild cards, mention table names without double quotes (for example, TABLE1).
Infer	Specifies whether you want to infer primary keys or relationships, or both	Primary Keys: Indicates that primary key columns are inferred for the tables that are based on defined indexes Relations: Indicates that the relationships between tables based on either primary key column names or defined indexes are inferred. Select this option and then specify whether to use primary key column names or defined indexes. The following options are available only when Infer is set to Relations. Indexes: Indicates that the relationships from the table indexes are inferred. Relationships are inferred from table indexes only if the primary key columns of the parent table are part of the index in the child table. Names: Indicates that the relationships from the primary key column names are inferred. Relationships are inferred from columns names only if all of the primary key columns of the parent are in the child table.
Case Conversion of Physical Names	Specifies how the case conversion of physical names is handled	None: Indicates that the case in the script file is preserved lower: Indicates that the names are converted to lower case UPPER: Indicates that the names are converted to upper case Force: Indicates whether the physical name property of all the logical/physical models is overridden. If this option is enabled, the logical/physical link is broken between the logical and physical name. If this option is not enabled, all logical and physical names are set to the same value after the process completes.
Case Conversion of Logical Names	Specifies how the case conversion of logical names is handled	None: Indicates that the case in the script file is preserved lower: Indicates that the names are converted to lower case UPPER: Indicates that the names are converted to upper case Mixed: Indicates that the mixed-case logical names are preserved
Include Generated Triggers	Specifies whether erwin-generated triggers are loaded during the reverse engineer process

Scheduler

The options on this tab are available only while reverse engineering via erwin DM Scheduler.

Parameter	Description	Additional Information
Model	Specifies the location and name of the reverse engineered model	For example: C:\Scheduler\<Model Name>.erwin When you schedule a job on a remote server, ensure the model path is same for remote and local server.
Mart Folder	Specifies the location or library in your mart where the reverse engineered model is saved	To use this option, ensure that you are connected to a mart. For more information, refer to the Connecting to Mart topic.
Complete Compare	Specifies whether the Complete Compare (CC) process should run while reverse engineering
Output File	Specifies the location of the CC output file generated
File	Specifies that the target model location is on the local system
Mart	Specifies that the target model location is in the mart
Using Latest Version	Specifies whether the target model is the latest version of the model in the mart	This option is available only when Mart is selected.
Save To Mart	Specifies whether the reverse engineered model is saved to the mart	This option is available only when Using Latest Version is selected.
Target Model	Specifies the location of the target model for CC
Option Set	Specifies the option set that is used for CC	Advanced Default Option Set: Indicates that all erwin DM metadata is included. CC works slowest with this option. Speed Option Set: Indicates that only the essential metadata is included. CC works the fastest with this option set. Standard Default Option Set: Indicates that standard metadata is included. CC works fast with this option set compared to the Advanced option set.

Parameter	Description	Additional Information
ODBC Data Source	Specifies the data source to which you want to connect. The drop-down list displays the data sources that are defined on your computer.
Invoke ODBC Administrator	Specifies whether you want to start the ODBC Administrator software and display the Select Data Source dialog. You can then select a previously defined data source, or create a data source.

Parameter	Description	Additional Information
System Objects	Specifies whether to include system objects for database selection
Available Databases	Displays the available databases
Selected Databases	Displays the selected databases

Parameter	Description	Additional Information
Available Tables	Specifies a list of available tables the selected databases for reverse engineering generation
Selected Tables	Specifies a list of selected tables for reverse engineering
