Gain a beginner overview of mainframes and databases, including db2, with a structured, video-based course and lifetime access to all lessons to help launch or advance a mainframe career.
Explore IBM's universal relational database Db2, designed to store, analyze, and retrieve data efficiently across Linux, Unix, and Windows, including its current Keppler version.
Manage multiple DB2 database instances on a single machine using the database manager. Create, start, stop, and upgrade instances across Linux, Unix, and Windows, with unique names and privileges.
Learn how IBM storage group environments organize databases with buffer pools, tablespaces, storage groups, and schemas, covering creation syntax, privileges, and storage management practices.
Explore data types, tables, aliases, and constraints in db2 mainframe development; learn to create and modify tables, use temporary tables and triggers, and manage indexes.
Explore indexes and their clustered and non-clustered types with creation and drop examples. Understand triggers, sequences, views, backup and recovery, and database security basics like authentication and roles.
Learn how to develop a cobol-cics-db2 program part 1 by using host variables to interact with db2, create and view tables, map data with copybooks, and compile with jcl.
Define connections, create maps, and install COBOL-CICS-DB2 programs and transactions, then compile, precompile, translate, and bind to run DB2 table access.
Practice the topics discussed in the video series to reinforce your understanding and gain a solid grip, and explore the many courses available for further learning.
DB2, developed by IBM, is a powerful Relational Database Management System (RDBMS) designed to efficiently store, analyze, and retrieve data. Widely used in mainframe environments, DB2 plays a critical role in enterprise applications, making it an essential skill for anyone aspiring to become a mainframe developer.
This course focuses on the foundational concepts of DB2, providing a clear and structured introduction for beginners. You will explore the basic architecture of DB2, understand how data is managed within the system, and learn the theoretical principles that underpin its operation. The program emphasizes building a strong conceptual base rather than advanced technical details, ensuring that learners gain the confidence to approach DB2 with clarity.
A highlight of the course is the inclusion of a COBOL‑CICS‑DB2 combination program, which demonstrates how DB2 integrates with other mainframe technologies. This practical example will help you see how DB2 fits into real‑world applications and why it is so valuable for developers working in mainframe environments.
Designed specifically for beginners, this course is not intended for experienced professionals. Instead, it provides the essential knowledge needed to start working with DB2 and prepares you for more advanced learning in the future.
