Abstract: An attribute-based component programming system and methodology for object-oriented languages is described. In one embodiment, for example, a method is described for dynamically generating program code adding behavior to a program based on attributes, the method comprises steps of: adding a component object to a program class of the program to create a component; defining at least one attribute specifying declaratively behavior to be added to the program; associating the at least one attribute with the component; and in response to instantiation of the component at runtime, generating a subclass based on the program class and the at least one attribute, the subclass including dynamically generated program code based on the at least one attribute.

Abstract: A method for cloning of prepared statements for execution against a database is described. In one embodiment, for example, a method for executing a database statement comprises steps of: preparing at least one template for execution of a statement against a database; storing the at least one template in a shared cache available to a plurality of database connections; in response to a request to execute a particular statement on a given database connection, determining whether a template for the particular statement is available in the shared cache; if the template is available in the shared cache, creating a database statement based on the template for execution on the given database connection; and executing the database statement on the given database connection.
