The data layer of FineReport is responsible for data management, including data collection, ETL, building a data warehouse, etc. Introduction 1m Module Overview 1m Domain-Centric Design 2m Onion Architecture 3m Demo 27m Summary of Refactoring 2m Starting from Scratch 1m Demo 5m Summary 2m What's Next 1m. So, we can create as many layers as possible but basically people classify code in three categories and put them in three layers. One-tier architecture involves putting all of the required components for a software application or technology on a single server or platform. 8.1 shows an example of a common multi-tier application design approach. Figure 1 shows an example of a simple, generic three-tier application. A simple example of a 3-tier architecture in action would be logging into a media account such as Netflix and watching a video. vmss-appName-business-layer). Three-Tier Architecture Overview The three-tier architecture is the most popular implementation of a multi-tier architecture and consists of a single presentation tier, logic tier, and data tier. One tier architecture has all the layers such as Presentation, Business, Data Access layers in a single software package. In our example, this is a web application, though multi-tier architectures can be used for other topologies as well (like desktop apps). Take FineReport as an example to help you better understand the 3-tier architecture. A four tier architecture consists of the following. The two tiers of two-tier architecture is This example scenario is applicable to any industry that needs to deploy resilient multitier applications built for high availability and disaster recovery. This chapter is a detailed description on multitier architectures. 1-tier Architecture In 1-tier architecture, the database is directly available to the DBMS user for executing the SQL queries and storing data in it. The traditional model of Multi-tier is still required today. With this design, the overall application framework is split into multiple pieces where the database server is separate from the application server, etc. Multi-Tiered Architecture In 3-tier architecture, each server (tier 2 and 3) performs a specialized task or service. This layer holds the query tools and reporting tools, analysis tools and data mining tools. N-tier application architecture provides a model by which developers can create flexible and reusable applications. Multi-tier architecture offers a less expensive approach through an intermediate tier of web services that absorb some of the network traffic burden. For example the presentation layer of a multi-tier architecture could be MVC. Most enterprise applications are designed with a multi-tier architecture. —Preceding unsigned comment added by NickHollingsworth ( talk • contribs ) 16:43, 29 May 2008 (UTC) Comparing MVC and 3-tier is a bad idea - it looks like it makes sense to compare them, but you're really comparing application architecture (MVC) with system architecture (3 tier). A multi-tier architecture designed as discussed here can be used in many types of apps. There are different approaches to multi-tier architecture and they have different recommendations. ... see the performance efficiency checklist in the Azure Architecture Center.
