All Control Systems that grow to any size have a variety of data that are stored in different formats on different nodes in the network. Examples include sensor value and status, archived sensor data, device oriented support data and relationships, message logs, application and machine configurations etc. Each type of data typically has a different programming interface. Higher-level applications need to access a logically related set of data that is in different data stores and may require different processing. AIDA is envisioned to be a distributed service that allows applications access to this wide variety of Control System data in a consistent way that is language and machine independent. It has the additional goal of providing an object-oriented layer for constructing applications on top of multiple existing conventional systems like EPICS or the SLC Control System. Motivation, design overview and current status will be presented.
