Following sections explain the reverse engineering options for DynamoDB in erwin DM.
Overview
|
Parameter |
Description |
Additional Information |
|---|---|---|
|
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 a remote or local database AWS CLI Script: Indicates that the model is reverse engineered from a Command Line Interface (CLI) script Python Script: Indicates that the model is reverse engineered from a python script |
| File | Specifies the script file location | This option is available when Script File is selected. |
Connection
You can connect to your DynamoDB database using your Access Key ID-Secret Access Key-Region credentials or your temporary Session Token credentials received using the get-session-token command.
|
Parameter |
Description |
Additional Information |
|---|---|---|
| Connection Method | Specifies the type of connection you want to use. Select DIRECT (CLOUD) to connect to a database on a cloud. Or, select DIRECT (LOCAL) to connect to a local database. |
|
| Hostname/IP | Specifies the hostname or IP address of the server where your database is hosted in the following format: http://localhost |
This option is available when Connection Method is set to DIRECT (LOCAL). |
| Port | Specifies the port configured for your database | For example, 9142. This option is available when Connection Method is set to DIRECT (LOCAL). |
| Access Key ID | Specifies access key id for connecting to a database on cloud | For example: AKIAI00EXAMPLE56OSFODNN7 This option is available when Connection Method is set to DIRECT (CLOUD). |
| Secret Access Key | Specifies access key for authenticating the database connection | For example: FEwJalrnMDMI/K7ENGXUt/EXAMPLEKEY/b1xwfiCu This option is available when Connection Method is set to DIRECT (CLOUD). |
|
Session Token |
Specifies the temporary session token for authenticating the database connection |
This option is available when Connection Method is set to DIRECT (CLOUD). Use the get-session-token command in AWS CLI to get the temporary security credentials. |
| Region | Specifies the location of the remote database |
For example: us-east-2 This option is available when Connection Method is set to DIRECT (CLOUD). This field is not mandatory if the region is configured using a AWS CLI. The system displays an error if the region is not configured in this field or using a AWS CLI. |
Tables
|
Parameter |
Description |
Additional Information |
|---|---|---|
| Available Tables | Specifies a list of available tables | |
| Selected Tables | Specifies a list of selected tables for reverse engineering |
Option Sets
|
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. |
Detailed Options
|
Parameter |
Description |
Additional Information |
|---|---|---|
| NSM Options | 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 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 |
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 |
erwin Project
|
Parameter |
Description |
Additional Information |
|---|---|---|
| erwin Project | Specifies whether to configure the model for an existing erwin project | |
| Model Name | Specifies the name of the erwin project | |
| Location | Specifies the location of the project |
