Reverse Engineering Options for AlloyDB

Following sections explain the reverse engineering options for AlloyDB.

Parameter

Description

Additional Information
Reverse Engineer From Specifies the reverse engineering source

Database: Indicates that the model is reverse engineered from database

Parameter

Description

Additional Information
Database Specifies the database to which you want to connect  
Authentication Specifies the type of authentication to use to establish a connection

Database Authentication: Indicates that database access credentials are used to establish a connection for reverse engineering.
User Name Specifies the user name to access the database Available when Database Authentication is selected.
Password Specifies the password to access the database
Connection Method Specifies the type of connection you want to use. Select JDBC to connect using JDBC. Or, select ODBC to connect using the ODBC data source that you have defined.  

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.

This option is available when Connection Method is set to ODBC.

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.

This option is available when Connection Method is set to ODBC.

For Reverse Engineering from a PostgreSQL or AlloyDB database, use the PostgreSQL ANSI ODBC driver.

Connection String

Specifies the connection string for PostgreSQL database server in the following formats:

  • jdbc:postgresql:database

  • jdbc:postgresql://host/database

  • jdbc:postgresql://host:port/database

This option is available when Connection Method is set to JDBC.

For example,

  • jdbc:postgresql:func

  • jdbc:postgresql://localhost/func

  • jdbc:postgresql://localhost:5432/func

Database

Specifies the name of the database to which you want to connect

This option is available when Connection Method is set to JDBC.

Parameters

Description

Additional Information
Available Owners Specifies a list of available owners in the databases  
Selected Owners Specifies a list of selected owners in the databases for reverse engineering  

Parameter

Description

Additional Information
Available Schemas Specifies a list of available schemas  
Selected Schemas Specifies a list of selected schemas for reverse engineering  

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  

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.

<Option Set Name> Specifies the objects to be reverse engineered according to the selected option set. You can edit this list.  

Parameter

Description

Additional Information
Glossary CSV File Specifies the naming standard glossary file in the .CSV format  
In TABLESPACEs (comma separated) Specifies the tablespaces that you want to set as filter criteria. To specify multiple tablespaces, use a comma-separated list. For exact matches, mention tablespace names in upper case inside double quotes(for example, "TABLESPACE1"). To use wild cards, mention tablespace names without double quotes (for example, TABLESPACE11).
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  

Include Public Synonyms

Specifies whether to include public synonyms during the reverse engineer process

 

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.

In addition to the above options, click Browse to select a custom option set for complete compare.

Compare Level

Specifies the selection type for the compare

Logical / Physical: Compares all objects on the logical or physical level of a model

Logical: Compares all objects on the logical level of a model

Physical: Compares all objects on the physical level of a model
