Logical architecture diagram example

What is logical architecture diagram?

Logical architecture is a structural design that gives as much detail as possible without constraining the architecture to a particular technology or environment. For example, a diagram that illustrates the relationship between software components. For example, a specification of software services and components.

What is a logical diagram?

A logical data flow diagram focuses on the business and how the business operates. It is not concerned with how the system will be constructed. Instead, it describes the business events that take place and the data required and produced by each event.

What is the starting point of logical architecture?

The completed logical architecture design and the system requirements derived during requirements analysis constitute the deployment scenario. The deployment scenario is the starting point for designing the deployment architecture , as explained in Chapter 5, “Designing a Deployment Architecture .”

What is system architecture diagram with example?

An architectural diagram is a diagram of a system that is used to abstract the overall outline of the software system and the relationships, constraints, and boundaries between components. It is an important tool as it provides an overall view of the physical deployment of the software system and its evolution roadmap.

What is the difference between physical and logical design?

In the logical design , you look at the logical relationships among the objects. In the physical design , you look at the most effective way of storing and retrieving the objects. Your design should be oriented toward the needs of the end users.

What are logical components?

Logical components : Represent concepts in the domain being studied, and are independent of the physical aspects of the software or hardware. Physical components : Represent actual software or hardware technology.

What is a logical process?

A logical level process model is used to model the detailed requirements of an application system. During analysis, the conceptual process model evolves into the detailed functional requirements, or logical process model. It describes the behaviour of processes and their interactions.

What is a logical network design?

A logical network is one that appears to the user as a single, separate entity although it might in fact be either an entity created from mutliple networks or just a part of a larger network . A logical network is defined by its IP addressing scheme.

What is physical and logical network diagram?

The two most common network diagrams you’ll come across are physical and logical . Logical network diagrams focus in on how traffic flows across the network , IP addresses, admin domains, how domains are routed, control points, and so on. Within the OSI model of networking , logical diagrams are referred to as ‘L2’.

What is the basic architecture of a computer system?

The different components in the Computer System Architecture are Input Unit, Output Unit, Storage Unit, Arithmetic Logic Unit, Control Unit etc. A diagram that shows the flow of data between these units is as follows − The input data travels from input unit to ALU.

What is physical architecture?

The physical architecture is the physical layout of a system and its components in a schema. It refers to some representation of the structure or organization of the physical elements of the system. The physical architecture should be part of the Allocated and Product Baselines.

What is deployment architecture?

A deployment architecture depicts the mapping of a logical architecture to a physical environment. The physical environment includes the computing nodes in an intranet or Internet environment, CPUs, memory, storage devices, and other hardware and network devices.

How do you read an architecture diagram?

An architecture diagram will tell you what the architect wants, plus details about the investors, the building contractors, and local laws. It may include a summary of the building, plumbing, and electrics — but its main goal is to show you how to meet all these groups’ needs.

What is system architect role?

A system architect analyzes and recommends the right combination of IT components to achieve a specific business, department, team, or functional goal. They objectively analyze desired processes and outcomes and advice on the right combination of IT systems and components to achieve those goals.

What is difference between design and system architecture?

Architecture means the conceptual structure and logical organization of a computer or computer-based system . Design means a plan or drawing produced to show the look and function or workings of a system or an object before it is made.
