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.
