Archiving (archiving) – consisting of a range of policies, processes, and technologies – has slowly become a necessary business for companies that comply with laws, regulations, and complex information technologies. While the company is facing an annual growth in critical data, storage capacity management technology bottlenecks have not improved. And the company also faces other challenges, such as keeping records in compliance with the rules and disclosing information in legal

High cost due to incorrect requirementsThe research completed at GTE, TRW, and IBM has measured and allocated three costs for identifying errors at different stages of the project lifecycle. These statistics are further validated by future studies 4. Although these studies are conducted independently, they all come to the same conclusion:CodeThe cost for detecting and fixing an error in the phase is one unit, so the cost for
is expected to provide a reusable messaging component to leverage existing investments in the Java EE Application Server, especially with existing EJB technologies.
An MDB can only be invoked asynchronously through a JMS message. Therefore, it does not have the local and remote interfaces that other beans have. Instead, the MDB implements two special interfaces: an interface to the EJB container (Javax.ejb.MessageDrivenBean), and a messaging interfa

the life cycle of a long term asset (a long-term asset). Capitalization is often used in tax returns and financial statements (such as profit and loss reports). Capital investment has become a part of the company's public assets. "Cost" means that the cost is immediately "affected", as "operating costs" in the short term to obtain returns or no value. A company that costs all software development will find it difficult to clarify that its software is part of long-term value.
