The organization structure system is part of the integrated information system of the Egyptian Armed Forces. It manipulates the units organization data (department, unit level, type, balance, armament, personnel, plan(s), percentage of completeness, location and position in the armed force tree). An initial survey for the problem is done. The design of the system is done through the E-R model and the functional dependency is defined. We choose the relational data base model for its advantages like data independent and simple data manipulation, over the other two DBMS models (hierarchical and network models). The system is designed in ten relations and the implementation is done through ingress using C programming language with equal (embedded ingres in C). This thesis presents several examples of queries that the system can support. An algorithm for collecting the units commanded by a particular unit is presented. The implementation includes the data definition of the ten relations in ingres. The data base editing program is presented which consists of 23 modules. This program is able to perform the addition, modification, deletion, and retrieval of units data keeping the data base in consistent state. The problems of recovery, concurrency, security and data integrity are also discussed.

1Wonders of the Jungle

By Sarath Kumar Ghosh

How do elephants drink? What is the Law of the Jungle at the water hole? How does an elephant baby learn to feed and learn to swim? How do they walk under water? In what order do buffaloes drink? How do buffaloes fight the tiger? These and other wild inhabitants of the Indian jungle such as pigs, wild dogs, deer, camels, bears and birds are discussed in lively stories to entertain but mainly educate children of school age. "One of the great thinkers of the world has said that all the sciences are embodied in natural history. Hence natural history should be taught to a child from an early age. Perhaps the best method of teaching it is to set forth the characteristics of animals in the form of a narrative. Then the child reads the narrative with pleasure and almost as a story, not as a tedious "lesson." In this book the animals are described in their daily life, and the main scientific facts and principles concerning each animal are woven into the narrative as a part of that daily life."
