Data deduplication. In computing, data deduplication is a technique for eliminating duplicate copies of repeating data. Successful implementation of the technique can improve storage utilization, which may in turn lower capital expenditure by reducing the overall amount of storage media required to meet storage capacity needs.

Don't repeat yourself. " Don't repeat yourself " (DRY) is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place. The DRY principle is stated as "Every piece of ...
Data redundancy. In computer main memory, auxiliary storage and computer buses, data redundancy is the existence of data that is additional to the actual data and permits correction of errors in stored or transmitted data. The additional data can simply be a complete copy of the actual data (a type of repetition code), or only select pieces of ...

Copy-on-write. Copy-on-write (COW), also called implicit sharing[1] or shadowing, [2] is a resource-management technique [3] used in programming to manage shared data efficiently. Instead of copying data right away when multiple programs use it, the same data is shared between programs until one tries to modify it.
In object-oriented programming, object copying is the act of creating and initializing a new object based on an existing object's state. The various ways to implement copy have implications that a programmer needs to understand in order to write a computer program that is correct and performant. Copying allows for the emergent state of the ...
