OOP language that create object, such as(1)and(2),are beginning to take hold as viable tools for programmers.To effectively reuse object, programmers need a place to store them such as an ODBMS or a RDBMS with object oriented extensions.
Databases that handle object data not only let user store and retrieve(3)data, but also let them store objects created by OOP languages, to facilitate rapid software development and reuse, and let them(4)new multimedia applications combining multiple data types.
RDBMS vendors have developed new extensions to exiting DB technology to accommodate the most common forms of(5)data.

Electronic mail, or mail, as it is known to its many fans, has been around for over two decades. Typically, email systems support five basic functions, as described below.(1)refers to the process of creating messages and answers.(2)refers to moving messages from the originator to the recipient.(3)has to do with telling the originator what happened to the message. Was it rejected? Was it lost?(4)incoming message is needed. So people can read their email.(5)is the final step and concerns what the recipient does with the message after receiving it。

The approach we propose is a system-oriented methodology for knowledge acquisition, this orientation emphasizes ongoing documentation throughout each cycle and technique applied. Program-wide documentation is suggested, both for the purpose ofinternal(1)and for later verification and(2)efforts. The documentation system we propose includes a central "knowledge acquisition(3)" which is(4)to reflect knowledge acquisition plans, session nodes, and domain expert participation. Specifically,(5)within the database system include knowledge acquisition forms, which document plans for, and notes from, knowledge acquisition session, domain expert file, and rule content forms.
In recent years, one of the more popular topics for panel discussions at computer conferences and trade(1)has been the "RISC versus CISC" debate.
RISC processors feature a small number of instructions that each executes in(2)machine cycle. CISC processors use complex instructions that can take several cycles to execute.
The RISC versus CISC debate won't be decided by panel discussion; it will be won in the marketplace. And the deciding factor may have little to do with the(3)ofinstructions and registers and more to do with parallelism.
Since their conception, RISC processors have been evolving toward microparallelism. Incorporating parallel-processing features(4)the processor, RISC processors feature pipelining, whereby many instructions can be decoded while one instruction executes. RISC processors, however, are moving toward pipelines for each unit of the processor.
CISC processors also employ pipelining. They have many integer instructions that execute in one cycle, but the varying execution times of CISC instructions(5)the effectiveness of parallelism.

Object-oriented DBMS integrated a variety of(1)data types—such as business procedures, graphics, pictures, voice and annotated text.
Object orientation also makes a(2)to application development efficiency. It makes the data, functions, attributes and relationships an integral part of the(3). In this way, objects can be reused and replicated.
Some leading RDBMS vendors support the concept of integrating object management capabilities with their current line of relational products. That capability enable users to(4)the development cycle, since integrity logic and business rules no longer need to be programmed(5)each application.
