middle layer
Center of three
Middle layer refers to an intermediate stratum between upper and lower boundaries.
In computing and software architecture, the middle layer (or middle tier) handles business logic between the user interface and the database: The middle layer processes requests before they reach the server.
In physical contexts, it describes whatever sits between outer surfaces: The middle layer of the cake was chocolate ganache.
