Query Management Facility (QMF) For End Users Z/OS

1. Interactive Querying: Users can submit ad-hoc SQL queries against DB2 databases interactively using a user-friendly interface. They can specify filtering criteria, sort order, and display options to retrieve and view data as per their requirements.

2. Data Visualization: QMF provides various options for visualizing query results, including tabular formats, charts, and graphs. Users can choose the most appropriate visualization method to analyze and interpret data effectively.

3. Report Generation: Users can create customized reports containing query results with headers, footers, titles, and page numbers. QMF offers formatting options to enhance the appearance and readability of reports.

4. Query Management: QMF allows users to save and manage their queries for future use. They can store queries in libraries, categorize them, and share them with other users. This feature promotes query reusability and collaboration among users.

Before learning Query Management Facility (QMF) for End Users on z/OS, it's beneficial to have a foundational understanding of the following skills:

1. Basic Mainframe Concepts: Familiarity with mainframe computing concepts, including z/OS operating system, JCL (Job Control Language), ISPF, TSO, and SDSF (System Display and Search Facility), is helpful for navigating the mainframe environment.

2. SQL: Understanding of SQL (Structured Query Language) is essential since QMF enables users to interactively query DB2 databases using SQL. Knowledge of SQL syntax, database objects (tables, views, indexes), SQL clauses (SELECT, WHERE, GROUP BY, ORDER BY), and basic SQL functions is necessary.

3. Database Fundamentals: A foundational understanding of database concepts such as data modeling, relational databases, normalization, and database management systems (DBMS) is beneficial for grasping the underlying principles of data querying and manipulation.

4. Data Analysis and Reporting: Proficiency in data analysis and reporting techniques is useful for interpreting query results, generating meaningful reports, and visualizing data effectively. Skills in data visualization tools and techniques can enhance the presentation of query results.

Learning Query Management Facility (QMF) for End Users on z/OS equips you with a range of valuable skills that are essential for interacting with DB2 databases on the mainframe environment. Here are some skills you gain:

1. SQL Proficiency: QMF enables users to execute SQL queries against DB2 databases. You'll gain proficiency in writing SQL queries to retrieve, manipulate, and analyze data stored in DB2 tables.

2. Database Navigation: You'll learn how to navigate and interact with DB2 databases effectively, including accessing tables, views, and indexes, understanding database schemas, and querying metadata.

3. Data Analysis: QMF provides capabilities for data analysis, allowing you to extract insights from large datasets, perform aggregations, filtering, sorting, and grouping of data to derive meaningful conclusions.

4. Report Generation: You'll acquire skills in generating customized reports using QMF, including formatting query results, adding titles, headers, footers, and incorporating calculations and summary statistics into reports.
