The document provides an overview of the requirements for an online railway reservation software system. It discusses the need to specify functionality, external interfaces, performance, attributes, and design constraints. It also outlines some key components of the system including an ER diagram describing the relationships between entities like customers, trains, seats, tickets; a structure chart categorizing different levels; and data flow diagrams showing the flow of data between processes.

3. SRS-Software Requirement Specifications The initial specification of user requirements may be based on interviews with the database users and on the designers own analysis of the enterprise. The basic issues that the SRS writer(s) shall address are the following: Functionality. What is the software supposed to do? b) External interfaces. How does the software interact with people, the system’s hardware, other hardware, and other software? c) Performance. What is the speed, availability, response time, recovery time of various software functions, etc.? d) Attributes. What are the portability, correctness, maintainability, security, etc. considerations?

4. An SRS should be a) Correct b) Unambiguous c) Complete d) Consistent e) Ranked for importance and/or stability f) Verifiable g) Modifiable h) Traceable e) Design constraints imposed on an implementation. Are there any required standards in effect, implementation language, policies for database integrity, resource limits, operating environment(s) etc.?

5. ER-Diagram: An entity-relationship (ER) diagram is a specialized graphic that illustrates the interrelationships between entities in a database. Structure chart: The entry for every type of categorization under consideration is given in a structure chart.

10. DFD Principles : The general principle in Data Flow Diagramming is that a system can be decomposed into subsystems, and subsystems can be decomposed into lower level subsystems, and so on. Each subsystem represents a process or activity in which data is processed. At the lowest level, processes can no longer be decomposed. Each 'process' in a DFD has the characteristics of a system. Just as a system must have input and output (if it is not dead), so a process must have input and output. Data enters the system from the environment; data flows between processes within the system; and data is produced as output from the system
