25.7 Summary and Concluding Remarks
Let us summarize what we have covered in this Chapter:
•
A Web-accessible database is simply a database that can be
accessed via the WWW.
•
Web-accessible databases provide a number of benefits to
companies and individuals that implement and/or use them.
Among the benefits are facilitation of e-commerce, broadening
of the company's scope of operation and market reach, a wide
range of conveniences, improved productivity, and improved
competitive advantage.
•
A Web-accessible database may be implemented as a two-tiered
system or a three-tiered system. Additionally, they may be C2B
or B2B.
•
The supporting technologies for Wed-accessible databases
include Web servers, server-side extensions, server interfaces,
XML, SOAP, WSDL, and client-extensions.
•
Both Oracle and DB2 implement Web-accessible databases as a
matter of policy.
•
Implementation of a Web-accessible database can be
summarized into two simple but profound steps: creating
the database and creating the Web-accessible user interface. The
tools used must meet minimum industry standards.
Web-accessible databases are among one of the technology-related phenomena that
have transformed life in the twenty-first century. They are expected to continue to be an
integral part of life in the foreseeable future.
