IBM Mainframe computers are primarily by large organizations for critical applications and bulk data processing, such as census, industry & consumer statistics, Enterprise resource planning and transaction processing.
IBM mainframe is a large computer system. Mainframe computers are useful for various large processing of data.
IBM Mainframe Softwares.
IBM Mainframe works under COBOL, Xdb/db2, CICS and JCL.
COBOL is a high level language useful for Mainframe computers. It is useful for business, finance and administrative systems for companies and govt. It is useful for solving a business problems.
Xdb/db2 is database useful for mainframes by using SQL for data operation. Db2 is a family of data management products.
CICS is a family of mixture language application servers that provide online transaction management and connectivity. CICS is an online transaction processing i.e., OLTP program for IBM.
JCL is Job control language. It is the command language of multiple virtual storage i.e., MVS is the commonly used operating system in the mainframe.
Five Books for improving your Knowledge.
Some books really help to grow your knowledge about mainframes. The following five books give you knowledge about COBOL, Xdb/db2, CICS and JCL.
“IBM Mainframe Handbook”.
Mainframe Professionals refers mostly IBM Mainframe Handbook to improve in-depth knowledge about IBM Mainframes. Mainframes basic about MVS, JCL, VSAM, CICS, DB2, IMS and VS COBOL II can be improved from this book.
“COBOL Programming including MS-COBOL and COBOL-85”.
COBOL Programming including MS-COBOL and COBOL-85 Book is useful to learn Introduction to computers, table handling, features of languages, structured programming, improved programming. M.K. Roy and D. Ghosh Dastidar wrote a book for COBOL in such a ways that professional can easily learn COBOL programming.
“Using The New DB2-IBM’s Object Relational Database System”.
Xdb/Db2 is a database used in IBM Mainframe. Learn DB2 from “Using the New DB2” book by Don Chamberlin. SQL is used for database systems.
“CICS for the COBOL Programmer.
CICS is a family of mixed language application servers that provide online transaction management and connectivity. CICS is a customer information control system. Learn more details about CICS from this book.
“The MVS JCL Primer”.
JCL is a job control language. MVS is the operating system used for IBM Mainframe. Learn MVS JCL from this book and improve your job on IBM Mainframe system.
These are important books useful for learning Mainframe computers.
