IBM DB400 Online Test

The IBM DB/400 Test makes use of scenario-based questions to test for on-the-job skills as opposed to theoretical knowledge, ensuring that candidates who do well on this screening test have the relavant skills. The questions are designed to covered following on-the-job aspects:

• Data modeling including schema design and normalization
• Data integration involving the extraction, transformation, and loading (ETL) of data
• Data migration from legacy systems to IBM DB400
• Performance tuning for optimizing database queries and improving overall system performance
• Backup and recovery strategies to ensure data availability and minimize downtime
• Implementing security measures to protect sensitive data
• Troubleshooting database issues and resolving errors
• Understanding and utilizing advanced SQL techniques
• Applying indexing and query optimization techniques
• Designing and implementing data warehouse solutions

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

• Data Modeling

  Data modeling is the process of designing a database structure that accurately represents the organization's data requirements. It involves identifying entities, attributes, and relationships, and creating logical and physical models. This skill should be measured in the test to evaluate a candidate's ability to create efficient and scalable database designs.

• Data Integration

  Data integration is the process of combining data from different sources into a unified format. It involves mapping and transforming data to ensure consistency and compatibility. Measuring this skill in the test helps assess a candidate's proficiency in integrating data from various systems.

• Data Migration

  Data migration is the process of transferring data from one system to another. It requires careful planning, validation, and execution to ensure data integrity and minimal disruption. Testing this skill allows recruiters to evaluate a candidate's ability to successfully migrate data while mitigating risks.

• Performance Tuning

  Performance tuning involves optimizing a database system to achieve maximum efficiency and responsiveness. It includes techniques such as indexing, query optimization, and resource allocation. Measuring this skill in the test helps determine a candidate's ability to enhance database performance and ensure optimal system functioning.

• Backup and Recovery

  Backup and recovery refer to the processes and strategies for safeguarding and restoring data in case of failure or loss. It includes creating backups, implementing recovery plans, and testing data restoration procedures. Evaluating this skill in the test helps recruiters gauge a candidate's proficiency in ensuring data availability and minimizing downtime.

• Security

  Security in the context of databases involves protecting sensitive data from unauthorized access, ensuring compliance with privacy regulations, and implementing appropriate security controls. Testing this skill allows recruiters to assess a candidate's knowledge of data security principles and their ability to implement effective security measures.

• Troubleshooting

  Troubleshooting involves identifying and resolving issues and errors in a database system. It requires a strong understanding of database operations, diagnostic techniques, and problem-solving skills. Measuring this skill in the test helps determine a candidate's proficiency in effectively troubleshooting database-related problems and maintaining system stability.
