MongoDB

Following sections explain the reverse engineering options for MongoDB.

Overview

Parameter	Description	Additional Information
Database	Specifies the reverse engineering process from a MongoDB
Script File	Specifies the reverse engineering process using a script

Connection

Parameter	Description	Additional Information
Connection Method	Specifies the type of connection you want to use. Select Direct to connect to connect to your database directly. Select Connection String to connect to your database using a connection string.
Hostname/IP	Specifies the hostname or IP address of the server where your database is hosted	This option is available when Connection Method is set to Direct.
Port	Specifies the port configured for your database	This option is available when Connection Method is set to Direct.
Database	Specifies the name of the database to which you want to connect	This option is available when Connection Method is set to Direct.
LDAP	Specifies whether to use LDAP protocol for authentication and authorization	This option is available when Connection Method is set to Direct.
Connection String	Specifies the connection string in the following format: mongodb://[username:password@]host1[:port1][,...hostN[:portN]][/[defaultauthdb][?options]]	For example, mongodb+srv://myusername:****@ cluster0.v7gra.mongodb.net/test?retry Writes=true&w=majority This option is available when Connection Method is set to Connection String. Connection string supports SSL certificate path and socket timeout parameter. When you connect to a local database using the SSL certificate, ensure that the connection string contains "tlsAllowInvalidCertificates=true" parameter.

Databases

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

Collections

Parameter	Description	Additional Information
Document Count	Specify the number of documents or percentage of total records that the newly generated model schema would contain
Deep Search	Specify whether the deep search algorithm is used to retrieve the right samples for schema generation
Sampling	Use the Sequence or Random sampling methods to sample records in the selected collections. Sampling enables you to retrieve right estimates for accurate collection schema generation.
Available Collections	Displays the available collections	MongoDB 5.x supports Time Series Collections. These collections are indicated using
Selected Collections	Displays the selected collections

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.
<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

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.

Detailed Options

Parameter	Description	Additional Information
Glossary CSV File	Specifies the naming standard glossary file in the .CSV format
Case Conversion of Physical Names	Specifies how the case conversion of physical names is handled	None: Indicates that the same case is preserved as it appears in the script file 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 not enabled, all logical and physical names are set to the same value after the process completes. If this option is enabled, the logical/physical link is broken between the logical and physical name.
Case Conversion of Logical Names	Specifies how the case conversion of logical names is handled	None: Indicates that the same case is preserved as it appears in the script file 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
Save Field Value	Specifies whether values of attributes or fields are saved to the model	Field values are saved and displayed on the MongoDB Collection Field Editor as follows: For multiple datatypes, field values are displayed under the Multiple Datatypes section. For other datatypes, field values are displayed under the General Option section in the Value field.

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 Database: Compares all objects on the database level of a model
