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.

Accessing data entities

A method includes receiving a request from a source service, determining whether the target service associated with the request supports a by-reference evaluation strategy, determining whether an information object associated with the request is a data reference, retrieving data associated with the reference from a database, adding the data to the information object, and invoking the target service and passing the information object to the target service responsive to determining that the target service does not support the by-reference strategy and the information object is a data reference.

Systems and methods involving information objects

A method to model and change the state of associated content objects from one or more workflow and task management systems is provided. The method includes overlaying a business process model associated with a graphical content state overlay. A state of the content objects changes accordingly when the business process instance proceeds. Access rights are forwarded from human tasks in a business process to an associated content object. Concurrent access rights that are forwarded from multiple systems are handled. The graphical content state overlay areas include an active state overlay to graphically indicate a business process instance is active, an assessed overlay to graphically indicate a business process instance is assessed, an approval/rejected overlay to graphically indicate a business process instance has received one of an approval decision and a rejection decision, and a state archived overlay to graphically indicate a business process instance has been archived.

Method and apparatus to model content state and access control in backend-systems and business processes

Method and system for providing results for task list queries to Workflow Management Systems (WfMSs) and Human Task Management Systems (HTMSs). In one aspect, a method for providing the result of a task list query to a human task database includes caching data from the database in a plurality of materialized views. A new request for a list of tasks from the database is received, and a new query is created when the new request applies to the data in a particular materialized view. When the particular materialized view includes data that requires updating from more recent data in the database, the materialized view is so updated. The new query is executed against the data in the materialized view instead of executing the new query against the data in the database.
