What are the three levels of architecture in step?

This architecture has three levels: the physical level, the conceptual level, and the exterior level. At the physical level, we have things like materials used to construct buildings and their appearance. At the conceptual level, we have things like functions and elements of a building. These include aspects such as interior rooms, exterior walls, doors, and windows. Finally, at the exterior level we have things like colors and designs used on buildings.

Physical architecture involves the design and construction of physical environments such as buildings and vehicles. It is also known as applied art because it can influence how people feel about their surroundings. Physical architects create these environments by choosing materials that provide functional benefits while looking good. They may also choose to incorporate their own artwork into a building's design.

Physical environments can affect people's emotions in many ways. A building can make someone feel comfortable or uncomfortable depending on what type of architecture it has. The look of a building can also affect how people feel. For example, a white building with black trim would be considered elegant, while a gray building with red trim would be more rustic. A building can be designed to fit its environment; for example, a factory might have very plain concrete walls while a store could be made out of wood.

What are the three levels of the three schema architecture?

Three-Schema Architecture is defined by Techopedia. The external level, sometimes known as the user level, is the first of the three levels. This is the view of the relational database that end users see, and it is quite abstract. The logical schema or conceptual level is the second level, where designers operate. Here, they create the appropriate tables and fields to model real-world things like customers or products. The physical schema or storage level is the third level. At this level, developers can control how data is stored in the database file.

What is a high-level design, with an example?

1. High Level Design: This comprises a description of system architecture, data base design, a brief explanation of systems, services, platforms, and module linkages. It is often referred to as "macro-level/system design." A solution architect designed it. This document will be used by developers to understand the big picture and to know what they should build.

2. Use Case Model: This shows how the system will be used by end users. Use cases are written at a very high level and can be used to explain any complex system or process. In this case, the use cases describe the functions of the product development cycle.

3. System Flowchart: This diagram illustrates how the use cases will interact with each other when executed by a human operator. The system flowchart shows which use cases must be performed in order for a user to achieve their goal. In this case, the system flowchart shows that after selecting development project information, the next step is to select a technology for the application. After making this selection, users will be taken to a screen where they can choose individual features within the selected technology. At the end of this process, users will be shown a summary of their decision making along with an estimate of the cost of developing their idea.

4. Module Diagram: This shows which components go into building a functioning system. It is also known as the physical design.

What are the three tiers of architecture?

The three-tier architecture is a well-known software application architecture that divides applications into three logical and physical computing tiers: the presentation tier, or user interface; the application tier, where data is processed; and the data tier, where the application's data is stored and managed.

The three-tier architecture was one of the first large-scale software design patterns introduced by Jeff Raskin in his book The Jargon File. In this book, Raskin argues that existing programming languages and tools were not adequate for modern computer applications, which required access to large amounts of data over a network. To address this need, he proposed an architecture consisting of three layers: a presentation layer written in a custom language called "HTML" (hypertext markup language); a business logic layer containing code written in whatever programming language is most appropriate for the task at hand; and a data access layer that interacts with any number of data sources, such as relational databases.
