Copy with Change in Hindi | Copy with Change in Software Engineering

In software engineering, "Copy with Change" is a technique in which existing software code, design, or system is duplicated and then changes are made to it based on specific new requirements.
This method is commonly adopted for software reuse and to quickly create new software versions.

"Copy with Change" is used when some parts of an existing software need to be reused, but using it without changes does not provide the desired functionality.
In this situation, instead of completely rewriting the existing system, small changes are made to it to include new functions. This saves time and also reduces development costs.

"Copy with Change" is an important technique in software engineering that makes the software development process faster and more economical. It increases the reusability of the system, and through it, the software development team saves time and effort.
However, it is also important that it is used wisely to avoid problems like duplication and technical debt.

Importance of Copy with Change in Hindi | Importance of Copy with Change:

The importance of "Copy with Change" in software development is as follows:

Time saving: There is no need to recreate already written code, which speeds up development.
Cost reduction: Reusing existing code and design reduces the cost of writing new code.
Quality improvement: The quality of existing code is already tested, which increases the reliability of the new software.
Risk reduction: Completely changing an existing system can have many types of risks. But, using "Copy with Change" reduces the risk.

Process of Copy with Change in Hindi | Process of Copy with Change:

This process includes the following steps:

Identification of existing code or design: First, those parts of the existing software system are identified that can be reused. For example, the existing code for customer data management for an inventory management system may already be available.

Making a copy of the code: The required modules or components are copied from the original system. This copy serves as the basis for the new system being created.

Planning the changes: It is necessary to know what changes are to be made to the existing code. In this step, a plan for changes is made according to the new requirements, so that the existing code can be reused to the maximum.

Implementation of changes: Now changes are made to that code or design. Such as adding new features, changing the UI, changing the data processing method, etc.

Retesting: After making changes, the new system is tested to ensure that the new functions are working as expected.

Rollout and maintenance: If the changes are successful, the new software version is rolled out and its performance is monitored.

Advantages of Copy with Change in Hindi | Advantages of Copy with Change:

Reusability: Reusing existing code speeds up development.
Flexibility: It can be easily customized for different projects and new users.
Innovation improvement: New functionalities can be added to existing software, making the system more modern.

Disadvantages of Copy with Change in Hindi | Disadvantages of Copy with Change

Technical Debt: Repeatedly doing "Copy with Change" increases the size of the codebase, which makes it difficult to maintain.
Duplication: There can be duplicate code in the system, which increases the complexity of development and maintenance.
Performance issues: Sometimes the copied code needs to be highly optimized, otherwise it can affect the performance of the system.

Examples of Copy with Change in Hindi | Examples of Copy with Change:

Development of a mobile application: A company has developed an e-commerce app and now wants to customize it for other countries as well. For this, "Copy with Change" can be used, in which the existing code is copied and the necessary changes are made according to the new countries,
such as language, tax calculation, currency, etc.

Customer Relationship Management (CRM) system: An organization wants to customize its CRM system according to another department. They can use the existing system by copying it and making the necessary changes according to the other department.

Inventory Management System: An inventory management system has an existing module for the product catalog. This is copied into a new system and changes are made to adapt it to the needs of the new business.
