Three Layer Architecture
Three-layer architecture divides an application into data layer , business logic layer and presentation layers.
Data Layer: It manages the stored data in the database.
Business Logic Layer: It manages the rules and regulations of business processing.
Presentation Layer: It accepts the user input and displays the desired output to the user.
A(n) static connection to a remote resource must be initialized by the user or a system
A connection to remote resources can be either static or dynamic and a user or a system administrator must know the resource name and server to create a static connection. A static connection can be created for printers or other shared resources.
Static and dynamic connections
Differences between static and dynamic connections to remote resources are given as follows:
Static connection type requires resource strategy because whenever resources are added, moved, named, updated, or deleted then just to reflect the changes all user's resources must be updated.
A resource registry must be located at an Operating System. A static connection must be established between local drive of computer system and the Shared Files folder on any server.
