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.

Abstract: A Component Transaction Server (CTS) is described, which provides a framework for deploying the middle-tier logic of distributed component-based applications. The CTS simplifies the creation and administration of Internet applications that service thousands of simultaneous clients. The CTS components, which execute on the middle-tier between end-user client applications and remote databases, provide efficient management of client sessions, security, threads, third-tier database connections, and transaction flow, without requiring specialized knowledge on the part of the component developer. The system's scalability and platform independence allows one to develop application on inexpensive uniprocessor machines, then deploy the application on an enterprise-grade multiprocessor server. In its Result Set module, the CTS provides tabular result sets, thus making the environment very desirable for business applications. In most component-based systems, a component interface returns an object.
