This course offers a comprehensive introduction to IMS for all those new to the IMS environment. It provides ideal cross-training for application support specialists from disciplines such as CICS, COBOL, JAVA, or DB2. The course introduces and explains all areas of IMS databases in both the Batch and Online environments, including data access using the DL/I Language Interface and the maintenance of data integrity using the DBRC feature. Written exercises reinforce the formal tuition sessions. These include the analysis of sample applications and use of the procedures and utilities required to recover from various application and system failures.

A general understanding of the IBM enterprise server (mainframe) computing environment and an appreciation of application development concepts is assumed.

describe the architecture of IMS batch and online systems
analyse database and communication calls
identify appropriate logical and physical database design features
describe the structure of secondary indexes and logical relationships
use IMS utilities to backup, restore, and reorganize the database
discuss the facilities available in IMS to provide data integrity and system availability.
trace the flow of a transaction through an IMS system

IMS Essentials Training Course in Netherlands

The Netherlands, which is also informally known as Holland, is a country located in Northwestern Europe with overseas territories in the Caribbean. The four largest cities are Amsterdam, Rotterdam, The Hague and Utrecht. Amsterdam is the country's most populous city and the nominal capital, while The Hague holds the seat of the States General, Cabinet and Supreme Court. Rotterdam is the second largest city and has the largest port in Europe. The importance of the Netherlands for Europe is so huge that it cannot be ignored. The country is a founding member of the European Union, Eurozone, G10, NATO, OECD, and WTO.

The tourist attractions of the Netherlands are windmills, canals, and tulips. Canals are an important part of Amsterdam's cityscape and Keukenhof, the Garden of Europe, is the largest public garden in the world. The National Museum Rijksmuseum and the Anne Frank House are must-see places in the Netherlands.
