Architectural styles for Software Design

1. Data-centered architecture

• The data store in the file or database is occupying at the center of the architecture.
• Store data is access continuously by the other components like an update, delete, add, modify from the data store.
• Data-centered architecture helps integrity.
• Pass data between clients using the blackboard mechanism.
• The processes are independently executed by the client components.

2. Data-flow architecture

• This architecture is applied when the input data is converted into a series of manipulative components into output data.
• A pipe and filter pattern is a set of components called as filters.
• Filters are connected through pipes and transfer data from one component to the next component.
• The flow of data degenerates into a single line of transform then it is known as batch sequential.

3. Call and return architectures

This architecture style allows to achieve a program structure which is easy to modify.

Following are the sub styles exist in this category:

1. Main program or subprogram architecture

• The program is divided into smaller pieces hierarchically.
• The main program invokes many of program components in the hierarchy that program components are divided into subprogram.

2. Remote procedure call architecture

• The main program or subprogram components are distributed in network of multiple computers.
• The main aim is to increase the performance.

4. Object-oriented architectures

• This architecture is the latest version of call-and-return architecture.
• It consist of the bundling of data and methods.

5. Layered architectures

• The different layers are defined in the architecture. It consists of outer and inner layer.
• The components of outer layer manage the user interface operations.
• Components execute the operating system interfacing at the inner layer.
• The inner layers are application layer, utility layer and the core layer.
• In many cases, It is possible that more than one pattern is suitable and the alternate architectural style can be designed and evaluated.

This architecture style allows to achieve a program structure which is easy to modify.
