About IBM DB/400 Assessment Test

An IBM DB/400 Assessment Test evaluates candidates on their proficiency in working with IBM's relational database management system (RDBMS) known as DB2 for IBM i, previously known as DB/400. This system is commonly used on IBM's midrange AS/400 and IBM iSeries systems.

A IBM DB/400 Assessment Test evaluates candidates for:

  1. DB/400 Basics:
    • Understanding of the DB/400 database system architecture, components, and its integration with IBM i operating system (OS/400 or IBM i).
  2. SQL Fundamentals:
    • Proficiency in Structured Query Language (SQL) for DB/400, including:
      • Querying data using SELECT statements.
      • Modifying data using INSERT, UPDATE, DELETE statements.
      • Creating and managing database objects such as tables, views, indexes, and sequences.
      • Using SQL functions (e.g., string functions, date functions) and aggregate functions (e.g., SUM, AVG).
  3. Data Definition Language (DDL):
    • Knowledge of DDL statements in DB/400 for defining database objects, including CREATE TABLE, ALTER TABLE, DROP TABLE, CREATE INDEX, and managing table constraints (e.g., primary key, foreign key).
  4. Data Manipulation Language (DML):
    • Skills in using DML statements for manipulating data in DB/400 tables, ensuring data integrity, and transaction control using COMMIT and ROLLBACK statements.
  5. Stored Procedures and Triggers:
    • Understanding of creating and managing stored procedures and triggers in DB/400, defining procedure parameters, implementing business logic, and automating database operations based on predefined conditions.
  6. Database Security and Access Control:
    • Knowledge of implementing security measures in DB/400, including user authentication, authorization using roles and privileges, securing database objects, and ensuring compliance with data protection regulations.
  7. Performance Tuning and Optimization:
    • Techniques for optimizing DB/400 database performance, including indexing strategies, query optimization, analyzing query execution plans, and monitoring database performance metrics.
  8. Backup and Recovery:
    • Skills in performing database backup and recovery operations in DB/400, implementing disaster recovery plans, managing backup schedules, and restoring data in case of database failures or data loss incidents.
  9. Integration with Application Development:
    • Ability to integrate DB/400 with application development frameworks and languages (e.g., RPG, COBOL, Java), accessing DB/400 data through ODBC or JDBC connections, and implementing data access layers in applications.
  10. IBM iSeries System Integration:
    • Understanding of integrating DB/400 with other IBM iSeries components and subsystems, managing data queues, job scheduling using Job Scheduler, and leveraging IBM i operating system features for batch processing and job management.
  11. Documentation and Best Practices:
    • Commitment to documenting DB/400 database schema, SQL queries, stored procedures, database maintenance tasks, and adhering to best practices for database design and administration.
  12. Continuous Learning and Development:
    • Commitment to staying updated with IBM iSeries and DB/400 updates, exploring new features (e.g., enhancements in DB2 for i), attending IBM i conferences, obtaining relevant certifications, and contributing to the IBM i community forums.

Overall, an IBM DB/400 Assessment Test assesses candidates' abilities to effectively manage and optimize DB/400 databases, develop robust SQL queries and procedures, ensure database security and integrity, and integrate database operations with IBM iSeries systems. This evaluation helps identify individuals who can contribute to maintaining reliable and high-performance database solutions on IBM i platforms using DB/400.
