Indicating a change to a data field in an electronic data entry form, such as a Web page, database form, or other electronic form. Upon loading an electronic data entry form, an initial content of each data field is stored. User interaction with a data field is detected, and the current content of the data field is compared to the initial content. If the content changes from its initial content, an indicator associated with the changed data field is activated. The indicator may include an icon displayed adjacent to the data field, a change in data field border, font, color, or other sensory characteristic. If a nested data field is modified, a second indicator may be activated for the nested data field. Any indicator may be deactivated if a reset function is activated, or the new data is submitted to a server or database for further action or permanent storage.

Techniques have been developed whereby concurrency control mechanisms such as nested databases can be expressed in terms of operations implemented by various flexible transaction processing systems. For example, one such implementation of nested databases is particularly suitable for transaction processing systems that provides a lock delegation facility and which allow specification of ignore-conflict relationships between locking capabilities. By providing techniques that support movement of objects from a database to a subdatabase thereof, as well as termination (e.g., commit or abort) of transactions and databases (including subdatabases), transaction processing systems can provide advanced transaction models with unconventional concurrency control mechanisms. Some realizations allow specification of uses of parameters with lock modes and facilitate transformation of such uses into a form suitable for utilization in execution environments that support ignore-conflict relationships.

Methods and systems are provided for exposing nested data in computer-generated documents in a transparent manner. A mechanism is provided for a client application to query a server application for a list of available file formats after an object is requested from a server application document for embedding into a client application document. Another mechanism is provided for the client application to request a particular format associated with the embedded object from the server application document. Once the client application obtains file format information available to the server application or associated with the particular object, the client application may utilize the obtained file formats for utilizing or operating on the embedded object according to the native file formats associated with the embedded object.

Provided are a method for parsing a bit stream including multiple data formats, and an apparatus and computer program including a set of parsers and parser-selection and invocation capabilities for handling parsing of multiple data formats. A first parser is selected and invoked to handle a first formatted component of the bit stream, and this selected parser selects and invokes a next parser which is capable of handling a differently formatted next component of the bit stream. This is differentiated from systems which rely on a single generic parser or a single high-level parser selection process, and is especially advantageous when parsing messages to enable message processing in systems in which a message can include multiple different, nested data formats.

A method and system for processing and managing requests for concurrent use of data. Nested databases are utilized in order to create different environments in which the data can be accessed and modified. For each transaction which is in existence, there is an indication or reference to a database or subdatabase associated with that transaction. There are also data structures which indicate, for each data item at issue, which database or subdatabase is associated with that item. The use of data structures relating the transactions, subdatabases, and data items allows the creation of spheres of control for the various transactions and subdatabases. Thus, data can be readily shared among a plurality of users. The creation of the subdatabases does not require plural copies of data and the database management system may be implemented using one copy of the data, although multiple copies may be utilized, if desired.
