What is the data access layer in N-tier architecture?
The data access layer is where the entities live and it is simply a model of the database like in the Model-View-Controller pattern. This is actually the reason why we call it a model since it is the model of the database.What is an N-tier database?
N-tier data applications are data applications that are separated into multiple tiers. Also called "distributed applications" and "multitier applications", n-tier applications separate processing into discrete tiers that are distributed between the client and the server.How many layers are there in N-tier architecture?
N-tier architecture usually divides an application into three tiers: the presentation tier, logic tier and data tier.In this setup, you have the presentation or GUI tier, the data layer, and the application logic tier.
The application logic tier. The data tier. The presentation tier.
