Software Development

Software design and implementation software design is a description of the structure of the software to be implemented. The data models and structure used by the system The infrastructure between system components and sometimes the algorithm we used Designers do not arrive at a finished design immediately, but develop a design in stage. There are various stages in which designers design these stages. These designs are as follows:

  1. Architectural design:- here, you identify the overall structure of the system, The principal components their relationship and how they are distributed. Identify the overall structure of the system, principal components, their relationships, and distribution.

    Activities:

    • Define high-level system architecture.

    • Specify the interactions between major components.

    • Determine how the system will be deployed.

Example- For an e-commerce platform, architectural design involves outlining components such as the user interface, product catalogue, shopping cart, payment processing, and order fulfilment, and defining how they interact with each other.

  1. Database design:- Here we design the system data structure and how these are to be represented in the database. Again, the work here depends on whether an existing database is to be reused or a new database is to be created. Design the system's data structure and how it will be represented in the database.

    Activities:

    • Define database tables, relationships, and constraints.

    • Determine data storage and retrieval mechanisms.

    • Consider whether to reuse an existing database or create a new one.

Example- In a customer relationship management (CRM) system, database design involves defining tables for customer information, interactions, and transactions, along with establishing relationships between them.

  1. Interface design:- Any interface design we design the interface between system components. This interface specification can be unambiguous with precise interface components that may be used by the other components without them having to know how it is implemented. Once interface specifications are agreed upon, the component can be separately designed and developed

    Activities:

    • Specify how components interact with each other.

    • Develop unambiguous interface specifications.

    • Allow components to be used without detailed knowledge of their Internal workings.

Example: For a mobile banking application, interface design involves detailing how the user interface communicates with the backend systems for functionalities like account balance, funds transfer, and transaction history.

  1. Component section and design:- Here in the component section and design, you search for reusable components. And if no suitable components are available we design new software components.

    Activities:

    • Identify existing components that can be reused.

    • Design new software components if no suitable ones are available.

    • Ensure compatibility and integration between components.

Example: In developing a content management system (CMS), component selection and design involves choosing or creating components for tasks such as content creation, editing, version control, and user access management.

this is all about the software development.
