A temporary state service protocol is utilized by clients to temporarily store and access data within rows of a database between different requests made by end users. Each client creates and manages one or more items for storing data in rows of the database independently from other clients. An Application Programming Interface (API) is used to create and interact with the data that is temporarily stored in items within rows of the database. Different clients may share data within a single item and the data may persist beyond a session ending. Different rows of the database may be related such that a procedure affecting one of the rows affects its related rows.
