Method and system for optimizing access to a datastore

A data processing system for optimizing access to a Datastore in an object-oriented environment, wherein said data processing system includes an object and an identification object, wherein said identification object is within a class object, said data processing system comprising:

• reception means for receiving a request to open said Datastore at said identification object;
• first sending means for sending said request from said identification object to said class object in response to receiving said request;
• determination means for determining whether said Datastore is open in response to receiving said request at said class object;
• opening means for opening said Datastore in response a determination that said Datastore is closed and sending a message to said identification object indicting that said Datastore has been opened;
• second sending means for sending a message to said identification object indicating than said Datastore has been opened in response to a determination that said Datastore is open;
• second receiving means for receiving a request to close said Datastore at said identification object;
• third sending means for sending said request from said identification object to said class object in response to receiving said request at said identification object;
• second determination means for determining whether other objects require said Datastore to remain open;
• closing means for closing said Datastore in response to a determination that a requirement that said Datastore remain open is absent;
• and
• fourth sending means for sending a message to said identification object indicating that said Datastore has been closed, wherein access to said Datastore is optimized.

A system for optimizing and closing of a Datastore comprising:

• a reception means for receiving a request from a requesting object to access a Datastore;
• access means for accessing said Datastore in response to receiving said request, said access means including:
• first determination means, responsive to receiving a request to open said Datastore at said reception means, for determining whether said Datastore is open;
• first opening means for opening said Datastore, responsive to a determination that said Datastore is closed;
• second opening means for virtually opening said Datastore, responsive to a determination that said Datastore is already opened;
• second determination means, responsive receiving a request to close said Datastore at said reception means, for determining whether a requirement exists for said Datastore to remain open;
• first closing means for closing said Datastore responsive to a determination that a requirement that said Datastore remain open is absent;
• and
• second closing means for virtually closing said Datastore, responsive to a determination that a requirement exists for said Datastore to remain open.

A method in a data processing system for optimizing access to a datastore in an object-oriented environment, wherein the data processing system includes a class object and a persistent identifier, the method comprising the data processing system implemented steps of:

• receiving a request from the persistent identifier to open the datastore at the class object;
• determining whether the datastore is open in response to receiving the request from the persistent identifier at the class object;
• opening the datastore in response to a determination that the datastore is closed and sending a message to the persistent identifier that the datastore has been opened;
• sending a message to the persistent identifier indicating that the datastore has been opened in response to a determination that the datastore is already opened;
• receiving a request from the persistent identifier to close the datastore;
• determining whether other objects require the datastore to remain open in response to receiving the request from the persistent identifier to close the datastore;
• closing the datastore and sending a message to the persistent identifier indicating that the datastore has been closed in response to a determination that a requirement that the datastore remain open is absent;
• and
• leaving the datastore open and sending a message to the persistent identifier indicating that the datastore has been closed in response to a determination that a requirement that the datastore remain open is present, wherein the datastore is virtually opened and closed by the persistent identifier and the class object provides a physical connection to the datastore wherein opening and closing of the datastore is optimized.
