Organizations rely on information systems to organize, process, and analyze data to support decision-making and operations. Information systems help organizations improve efficiency, communication, and productivity by providing access to accurate and timely information. In turn, organizations shape the design and implementation of information systems to align with their business goals and strategies.
The relationship between the information system life cycle and the database system development life cycle is that the informational systems help management entities to shift and move resources from one department to another easily by using a shared database system.
ICIS stands for Integrated Chemical Information System, which is a database used to access information on the chemical industry, including market data, pricing, and news.
The information system lifecycle focuses on the entire system development process, including planning, analysis, design, implementation, and maintenance. The database system development lifecycle is a subset of this, specifically focusing on the database design, implementation, and maintenance within the broader information system context. Both lifecycles work together to ensure that the database system supports the overall information system requirements and objectives.
In an Entity-Relationship Diagram for a patient information system, you may have entities like Patient, Doctor, Appointment, Prescription, and Medical Record. The relationships between these entities could include a Patient having many Appointments, a Doctor treating many Patients, and a Prescription being linked to a specific Patient. Attributes for each entity would include things like patient ID, doctor ID, appointment date, prescription details, and diagnosis information.
Information flow diagram is used to visually represent the flow of information within a system, showing how data is input, processed, and output. Entity Relationship diagram is a visual representation of the relationships between entities in a database, illustrating the structure of the database and how data is organized. Both diagrams help in understanding and designing systems more effectively.
What is a synergistic relationship in an information system?
Entity Relationship Diagrams (ERD's) are a way of diagrammatically showing entities in an organisations and how they relate to each other. ERD's show detailed representations of the information that is used in a system and how it relates to other data. There are a number of symbols that represent the entities and the relationships between them; the relationship can be a one to many relationship, many to many or one to one.
Management Information System is a type of Information System. It is used by middle management to keep taps on the activities of the organisation. It helps them in making informed decisions.

For the most part, the client system sends a request for information to the server. The server receives the request and then sends the appropriate information to the client. The client then receives the information from the server.
Most organisations have become completely dependant on its information systems for running the organisation. Information has become the most valuable resource for organisations. However, the information system of an organisation needs to keep abreast of changes in the environment to produce information that is relevant to the management of the organisation.
