# Mapping for Proposal

In the Solidity programming language for Ethereum, a mapping is a data structure that enables programmers to store and access data in a key-value manner. The mapping for proposals in a Decentralized Autonomous Organization (DAO) can be used to link each proposal to its specific identity and current status. The mapping can be used to keep track of which proposals have been made, which are up for vote right now, which have been carried out, and which have been rejected. This data can be used to ensure that proposals are properly executed and recorded on the blockchain, as well as to enforce rules and restrictions on the proposal process, such as proposal caps and voting windows.
