Database Examiner Modernization Guide

Database Examiner is a Windows-based tool used to verify CA Erwin data models, specifically within a DB2 on z/OS environment. It helps ensure that data models are accurate and consistent, preventing potential data integrity issues. If an organization did not use this product, they might face inconsistencies and errors in their data models, leading to data-related problems.

Database Examiner is primarily a tool, designed to work with and validate data models. It is not a complete system, application suite, framework, or middleware. It focuses on a specific task within the data management lifecycle: ensuring the accuracy of data models.

This product is suitable for organizations that use CA Erwin for data modeling and have a DB2 database environment on z/OS. These organizations are typically medium to large enterprises in industries such as finance, insurance, and government. A company should consider using Database Examiner when they need to ensure the accuracy and consistency of their data models to avoid data-related issues.

A company should consider using Database Examiner when they need to ensure the accuracy and consistency of their data models, especially in a DB2 on z/OS environment. This is particularly important when changes are made to the data model or when migrating data between systems. It is not a good fit if the organization does not use CA Erwin for data modeling or does not have a DB2 database on z/OS.

Alternatives to Database Examiner include other data modeling validation tools or manual data model review processes. However, these alternatives may not provide the same level of integration with CA Erwin or the same level of automation. Some organizations may also develop custom scripts or tools to validate their data models.

Database Examiner requires a Windows environment for the client component and a DB2 database on z/OS for the server component. It also requires CA Erwin data models to be available for validation. The product extends and enhances CA Erwin Data Modeler by providing validation capabilities.

For mainframe products: Database Examiner runs in an LPAR on z/OS, dependent on the DB2 subsystem. It requires DB2 to be properly configured and accessible. The Windows client communicates with the DB2 subsystem on z/OS to perform data model validation.

The specific commands and syntax used by Database Examiner are not publicly available. However, the tool likely provides a graphical user interface (GUI) for users to interact with and perform validation tasks. Configuration files or interfaces would be used to specify the connection parameters to the DB2 database on z/OS and the location of the CA Erwin data models.

The API and integration capabilities of Database Examiner are not publicly documented. However, it is possible that the product exposes APIs for integration with other data management tools or systems. The specific API endpoint patterns and method names would depend on the implementation of the product.

Database Examiner helps organizations ensure the accuracy and consistency of their data models, which can lead to improved data quality and reduced data-related errors. This can result in cost savings by preventing data corruption and improving decision-making. The product also helps organizations comply with data governance and regulatory requirements.

The typical licensing model for Database Examiner is not publicly available. However, it is likely that the product is licensed on a per-user or per-installation basis. The total cost of ownership would include the cost of the license, as well as the cost of implementation, training, and ongoing maintenance.

Vendor lock-in considerations may exist if the organization relies heavily on Database Examiner for data model validation. However, the organization can mitigate this risk by developing internal expertise in data model validation and by using open standards for data modeling.

The specific authentication methods supported by Database Examiner are not publicly available. However, it is likely that the product supports standard authentication methods such as username/password authentication and integration with directory services such as LDAP. The access control model used by the product is also not publicly documented.

The encryption used by Database Examiner is not publicly documented. However, it is likely that the product uses encryption to protect sensitive data in transit and at rest. The audit and logging capabilities of the product are also not publicly available.

Database Examiner is typically deployed on-premise, with the Windows client installed on user workstations and the server component running on the z/OS mainframe. The level of technical expertise required to implement the product is moderate, requiring knowledge of Windows, DB2, and z/OS.

Ongoing operational requirements for Database Examiner include monitoring the performance of the product, performing regular backups, and applying security patches. Common implementation challenges include configuring the connection to the DB2 database on z/OS and ensuring that the CA Erwin data models are accessible.
