1. Introduction
This report revolves around a Heat Company and its needs. The aim of this project is
to model a real time software which is needed in CHCSV10 project. Actually, this company
wants to monitor the heat availability with the implementation of Central Heating control
V10 project. The objective of CHCSV10 project refers to producing heating equipment for
both residential facilities and for non-residential facilities. On the other hand, the actual aim
of CHCSV10 project’s plan is to release a new line of gas fired central heating system, to
meet the requirements of monitoring the heat availability, where a central heating control
system of new version is used. This project ensures to have automated facility for monitoring
all the aspects of central heating facility.
The objective of this report is to find the required facilities to achieve this facility. The
software engineering methodology will be used for completing the real time structure
analysis specification for CHCSV10 project. The External entity relationship diagram,
process specification, Control specifications, data dictionary and, data and control flow
diagrams will be studied and used to complete this project.
2. ERD
The entity relationship diagram is abbreviated as ERD and it is also called as entity
relationship model. Generally it refers to a graphical representation of information system
which depicts the relationship among the following- people, objects, places, events in a
system. This diagram helps in defining the business processes. On the other hand, it also acts
as a foundation of the relational database. Later, the relationship between the attributes and
entities is defined by the cardinality notation.
