What is the result of having a one-tier model for database applications?

A one-tier model for database applications combines both the database and the application within a single layer, which significantly simplifies deployment. When using this model, there is no need for complex communication between different layers, as everything operates within a single environment. This integration means that developers can streamline the application development process, making it easier to manage and deploy. Moreover, end users have a straightforward experience, as they are interacting directly with the application without any intermediary layers.

This simplicity often leads to reduced resource requirements, as there is no need for additional infrastructure to support multiple tiers or layers. It is particularly beneficial in scenarios where applications are intended for use on localized systems or where network access isn’t a primary concern. The one-tier model is effective for smaller applications or databases where the overhead of managing a multi-tier architecture is not justified.

In contrast, while the other options touch on aspects like complexity, security, and accessibility, they do not accurately represent the advantages of a one-tier model. It does not inherently guarantee enhanced security or fault tolerance, nor does it limit accessibility to different platforms, as it is generally easier to access a singular model.
