2 Tier Architecture in DBMS
2 tier architecture in DBMS
In this article, we will learn about 2 Tier Architecture in DBMS.
- DBMS architecture plays a key role in the design, development, implementation, and maintenance of the database management system of the company
- The proper selection of database architecture will solve many design problems initially and also helps in quick and secured data access
- Any database management system uses any of the following to 2 architectures
- 2 tier architecture (two-level)
- 3 tier architecture (three-level)
Two Tire architecture
two-tier architecture is similar to the basic Foundation model i.e client-server model
Components of two tire architecture
It consists of two tires
1. Client-side application:
- User interfaces and application programs run generally on the client-side
- It is generally a presentation layer that runs on a client (PC, Mobile, Tablet, etc)
- This client application establishes a connection by sending a request to the server-side up an application in order to establish communication between the database
2. Server side application
- The server side is responsible for query processing and transaction management
- In this, client-side directly communicates with the database base that is present on the server-side and the server sends a response to the request received from the client
- Simply server-side represented data is stored on a Server.
- Generally, APIS like ODBC, JDBC is used for this interaction i.e for sending requests from the client-side application.
Real-time examples for two-tier architecture
- Desktop applications excel sheets, word document, desktop games
- The contact management system that is created using MS Access is the most observed example is for this two-tier architecture.
Advantages of two-tier architecture
- As it is simple and easily understandable provides direct and faster communication
- Compatible with existing systems
- Provides some secretary to the DBMS as it is not directly e exposed to the end-user range.
Limitation of this two-tier architecture
It cannot be used for dynamic web applications where there are a large number of users and generally used for static desktop and small web applications.
