What Is A Logical Architecture?

The logical architecture is defined as the organization of the subsystems, software classes, and layers that make the complete logical system. The components are placed randomly in the system; that is why it is called logical architecture.

What is meant by logical architecture?

Logical architecture is a structural design that gives as much detail as possible without constraining the architecture to a particular technology or environment. Physical architecture gives enough detail to implement the architecture on a technology. For example, a specification of software services and components.

What is the difference between logical and physical architecture?

The primary difference between logical and physical architecture documentation is that, while logical architecture’s concerns end with identifying functional elements of the system, physical architecture takes an additional step, specifying actual devices that those functional elements execute on.

What are the main logical layers in the software architecture?

The logical architecture of typical enterprise applications is typically structured in three layers (Fig. 13.1): the data access layer, the processing layer, and the presentation layer.

What is the physical architecture?

(1) A physical architecture is an arrangement of physical elements (system elements and physical interfaces) which provides the design solution for a product, service, or enterprise, and is intended to satisfy logical architecture elements and system requirements.

What is the difference between conceptual and logical architecture?

The main difference between conceptual and logical data model is that conceptual data model represents entities and their relationships, while logical data model provides more details including attributes, primary and foreign keys in addition to entities and the relationships.

What are logical components?

Definition. A logical component is an administrative entity which assigns logical systems, in the entire system landscape and across projects, to the following: the system roles or phases in a project, e.g. the system role development system for the configuration.

What is logical infrastructure?

The path in which traffic flows through a network appears differently depending on your point of view. For example, from a network technician’s point of view, a packet travels through the network in a hop-by-hop path across each physically connected device.

What are the levels of architecture?

The three levels present in this architecture are Physical level, Conceptual level and External level.

What are logical layers?

The logical layer determines the logical transmission paths between sources and destinations. The physical layer is responsible for sending packets from one end to the other end of the logical link. That is to say, the real packet transmission process is in the physical layer.

What is a layer in logical architecture?

A layer is a large-scale element, often composed of several packages or sub- systems. The Layers pattern relates to the logical architecture; that is, it describes the conceptual organization of the design elements into groups, independent of their physical packaging or deployment.

What is logical view in software architecture?

Logical view: Describes how the system is structured in terms of units of implementation. The elements are packages, classes, and interfaces. The relationship between elements shows dependencies, interface realizations, part-whole relationships, and so forth.

What is the purpose of logical architecture?

The logical architecture is considered a type of structural design that is used to provide a detailed description of the system without defining the system technology or environment. It includes all the information related logically and detailed description without using technical terms in it.

What do you mean by logical and physical 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 is a logical application?

32 Logical Application Component. An encapsulation of application functionality that is independent of a particular implementation. For example, the classification of all purchase request processing applications implemented in an enterprise.
