Dietz, Fully Persistent Arrays. Proceedings 1st Workshop on Algorithms and Data The data structure is fully persistentif every version can be both accessed and modified. If there is also a meld or merge operation that can create a new version from two previous versions, the data structure is called confluently persistent. Structures that are not persistent are called ephemeral. [2] See more In computing, a persistent data structure or not ephemeral data structure is a data structure that always preserves the previous version of itself when it is modified. Such data structures are effectively See more In the partial persistence model, a programmer may query any previous version of a data structure, but may only update the latest version. This implies a linear ordering among each version of the data structure. In the fully persistent model, both … See more Next Element Search or Point Location One of the useful applications that can be solved efficiently using persistence is the Next Element … See more Perhaps the simplest persistent data structure is the singly linked list or cons-based list, a simple list of objects formed by each carrying a reference to the next in the list. This is … See more Copy-on-write One method for creating a persistent data structure is to use a platform provided ephemeral data structure such as an array to store the data in … See more Path copying is one of the simple methods to achieve persistency in a certain data structure such as binary search trees. It is nice to have a general strategy for implementing … See more Haskell Haskell is a pure functional language and therefore does not allow for mutation. Therefore, all data … See more
