摘要:
Data entities in a client-server system are accessed. The client-server system comprises a set of clients, a server system, and a repository for storing a plurality of data entities. The server system comprises an inter-transactional cache, the inter-transactional cache being accessible for each client of the set of clients. A first client of the set of clients comprises a first intra-transactional cache. If a copy of a first data entity is in the inter-transactional cache, a version identifier of the original first data entity is read from the repository. If the copy of the first data entity is to be accessed with an exclusive lock, a copy of the copy of the first data entity is added to the first intra-transactional cache. The copy of the copy of the first data entity in the first intra-transactional cache is accessed for further processing of the first data entity by the first client.
