Abstract: A system and method of collaborative processing of service requests includes receiving a service request at an application server, beginning execution of a proxy member function of a proxy class, and determining whether a movable member function in a movable class is to be executed at a client. When the movable member function is to be executed at the client, the method further includes creating a partial response including code for the movable class and information for invoking the movable member function and transmitting the partial response to the client fore execution of the movable member function. When the movable member function is not to be executed at the client, the method further includes executing the movable member function in the application server and returning a result of the movable member function as a result of the proxy member function. The proxy member function replaces the movable member function.

Abstract: A system and method of managing immutable objects includes monitoring new object construction, detecting construction of an object, determining a key for the object, looking the key up in a persistent storage system, when the key is found in the persistent storage system, loading the object from the persistent storage system, and when the key is not found in the persistent storage system constructing the object, determining whether the object is immutable, and storing the object in the persistent storage system when the object is immutable. In some examples, determining whether the object is immutable includes examining each primitive type data member of the object, examining each reference type constructor parameter of the object to determine whether the reference type constructor parameter is defensively copied, examining all function calls used by the object to determine whether the function calls preserve immutability, and recursively examining each reference type data member of the object.

Abstract: An example method of controlling access to data stored in a plurality of autonomous data sources includes receiving a federated query including a plurality of source queries. The method also includes receiving a request to submit a source query to a target data source. The method further includes determining whether the request matches at least one rule stored in a rules database. A rule that includes a given query matches a request that includes the given query. The method also includes when it is determined that the request does not match a rule stored in the rules database, sending a communication to cause (i) the source query to be submitted to the data source, and (ii) an initial result of the source query to be masked. The initial result of the source query has the same structure as the masked result of the source query.

Abstract: Various examples are directed to systems and methods for managing a database organized according to a schema. The database may comprise a database file corresponding to a table described by the schema. The database file may comprise a first row entry corresponding to a first row of the table. The first row entry may comprise at least one data item. A command may be received. The command may modify a first data item in the first row of the table. An indication of the modified value for the first data item may be written to a change location at the first file. The first entry may be modified to include a pointer to the indication of the modified value for the first data item.
