Basically high level we can say that 2-tier architecture is Client server application and 3-tier architecture is Web based application. Below I am concentrating on the difference between Two-Tier and Three-Tier Architecture, what all advantages, disadvantages and practical examples.

They are often used in applications as a specific type of client-server system. Doing so gives greater flexibility to development teams by allowing them to update a specific part of an application independently of the other parts. This added flexibility can improve overall time-to-market and decrease development cycle times by giving development teams the ability to replace or upgrade independent tiers without affecting the other parts of the system. For example, the user interface of a web application could be redeveloped or modernized without affecting the underlying functional business and data access logic underneath.

JDBC Architecture

It helps to design, develop, implement, and maintain the database management system. A DBMS architecture allows dividing the database system into individual components that can be independently modified, changed, replaced, and altered.

It also helps to understand the components of a database. A Database stores critical information and helps access data quickly and securely.

A simple one tier architecture example would be anytime you install a Database in your system and access it to practice SQL queries. But such architecture is rarely used in production. Two tier architecture provides added security to the DBMS as it is not exposed to the end-user directly. It also provides direct and faster communication.

Three Tier architecture contains a presentation layer, an application layer, and a database server. The application layer business logic layer also processes functional logic, constraint, and rules before passing data to the user or down to the DBMS.

The goal of Three Tier client-server architecture is: To separate the user applications and physical database To support DBMS characteristics Program-data independence Supporting multiple views of the data Three Tier Architecture Example: Any large website on the internet, including guru Summary An Architecture of DBMS helps in design, development, implementation, and maintenance of a database The simplest database system architecture is 1 tier where the Client, Server, and Database all reside on the same machine A two-tier architecture is a database architecture in DBMS where presentation layer runs on a client and data is stored on a server Three-tier client-server architecture consists of the Presentation layer PC, Tablet, Mobile, etc.

SQLite offers a lot of different installation packages, depending on your operating systems. What is auto increment? A Cursor is a pointer to this context area. Oracle creates context area Home Testing. Must Learn! Big Data. Live Projects. What is Database Architecture?

Now, we will learn about different architecture of DBMS with diagram. A 3-tier architecture has the following layers:. What is MySQL 5. The new release of MySQL 5.

N Tier(Multi-Tier), 3-Tier, 2-Tier Architecture with EXAMPLE

Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available. In the two-tier model, a Java application talks directly to the data source. This requires a JDBC driver that can communicate with the particular data source being accessed. A user's commands are delivered to the database or other data source, and the results of those statements are sent back to the user. The data source may be located on another machine to which the user is connected via a network. The network can be an intranet, which, for example, connects employees within a corporation, or it can be the Internet.

An N-Tier Application program is one that is distributed among three or more separate computers in a distributed network. The most common form of n-tier is the 3-tier Application, and it is classified into three categories. User interface programming in the user's computer Business logic in a more centralized computer, and Required data in a computer that manages a database. In N-tier, "N" refers to a number of tiers or layers are being used like — 2-tier, 3-tier or 4-tier, etc. The n-tier architecture is an industry-proven software architecture model.

Database architecture can be seen as a single tier or multi-tier. But logically, database architecture is of two types like: 2-tier architecture and 3-tier architecture.

Database Architecture in DBMS: 1-Tier, 2-Tier and 3-Tier

In this article I will show a simple example to demonstrate about the two types of architecture. In this article we are going to discuss about the two-tier and three-tier architecture. Two-Tier Architecture: The two-tier architecture is like client server application. The direct communication takes place between client and server.

Two-Tier Database Architecture — In two-tier, the application logic is either buried inside the User Interface on the client or within the database on the server or both. Three-Tier Database Architecture — In three-tier, the application logic or process lives in the middle-tier, it is separated from the data and the user interface. Three-tier systems are more scalable, robust and flexible.

Two-Tier and Three-Tier Architecture with example

It helps to design, develop, implement, and maintain the database management system.

3-Tier Architecture: A Complete Overview

The DBTG recognized the need for a two-level approach with a system view called the schema and user views called sub-schemas. The levels form a three-level architecture that includes an external, a conceptual, and an internal level. The way users recognize the data is called the external level. The way the DBMS and the operating system distinguish the data is the internal level, where the data is stored using the data structures and file.

The design of a DBMS depends on its architecture. It can be centralized or decentralized or hierarchical. The architecture of a DBMS can be seen as either single tier or multi-tier. An n-tier architecture divides the whole system into related but independent n modules, which can be independently modified, altered, changed, or replaced. Any changes done here will directly be done on the DBMS itself.


N-Tier architecture is an industry-proven software architecture model. In this tutorial, you will learn-. What is A diagrammatic representation of an n-tier system depicts here – presentation, application, and database layers.


 Да, я.  - Она наклонилась к микрофону и четко произнесла: - Сьюзан Флетчер. Компьютер немедленно распознал частоту ее голоса, и дверь, щелкнув, открылась.

 - Какие такие данные. Танкадо отдал кольцо. Вот и все доказательства. - Агент Смит, - прервал помощника директор.

 - С какой стати такой параноик, как Танкадо, доверился столь ненадежному типу, как Хейл. Сьюзан понимала, что теперь это не имеет никакого значения.

2-Tier Architecture​​ A 2 Tier Architecture in DBMS is a Database architecture where the presentation layer runs on a client (PC, Mobile, Tablet, etc.), and data is stored on a server called the second tier. Two tier architecture provides added security to the DBMS as it is not exposed to the end-user directly.
