Each layer has a different purpose and they all work together to provide a complete four-tier architecture. <\/p>\n
The presentation layer is responsible for handling the user interface and interaction with the user. It is the layer that the user interacts with directly. <\/p>\n
The data service layer is responsible for providing data to the presentation layer. It is the layer that interacts with the data access layer to retrieve data. <\/p>\n
The business logic layer is responsible for processing data and making business decisions. This layer contains the business rules that are applied to the data. <\/p>\n
The data access layer is responsible for storing and retrieving data from the database. This layer contains the database connectivity and access code.<\/p>\n
Which of the following is an example of a 3 tier architecture <\/h3>\n
A three-tier architecture is a type of software architecture that is composed of three distinct logical and physical computing tiers. The tiers are presentation, application, and data, and are interconnected by a network. A three-tier architecture is typically deployed on a public facing web server, an internal application server, and a database server.<\/p>\n
Three-tier architecture is a very common architecture for client-server applications. However, in recent years, many three-tier applications have been migrated to the cloud or containerized using cloud-native technologies. These changes have modernized these applications and made them more scalable and reliable.<\/p>\n
What is the difference between MVC and 3 tier architecture? <\/h2>\n
MVC is a pattern used to make UI code easier to maintain and test. When the MVC pattern is used, a larger portion of the UI code can be unit tested. 3 tier architecture is a pattern used for a completely different reason. It separates the entire application into meaningful “groups”: UI, Business Logic, Data Storage.<\/p>\n
The Balwant Rai Mehta Committee was a committee set up by the Government of India in January 1957 to examine the working of the Community Development Programme and the National Extension Service and to suggest measures for their better working. The committee submitted its report in April 1957.<\/p>\n
The committee recommended the setting up of three-tier panchayats, with Gram Panchayats at the village level, Panchayat Committees at the block level, and Zilla Parishads at the district level. It also recommended that panchayats be given adequate financial resources, and that they be empowered to levy and collect taxes.<\/p>\n
Conclusion <\/h2>\n
The three-tier architecture is a software architecture pattern that divides a computing system into three distinct tiers: the presentation tier, the application tier, and the storage tier.<\/p>\n
The three tier architecture is a popular architecture pattern used in software development. It is a logical separation of the presentation, business, and data access layers in an application. This separation of concerns can make development and maintenance easier. The three tier architecture is a popular choice for web applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
