In a
Web-enabled environment, the application may need to be online 7/24 and
support many time zones simultaneously. The data administration and oper-
ations activities include system management, configuration management,
asset management, and ongoing operations and tuning. These activities can
be automated or manually applied in the application environment. Applica-
tion data must also be secured against viruses, unauthorized access, and
data corruption. Ongoing operations include processes and procedures for
maintaining data stores, regular backups, and data recovery procedures.

As organizations and individuals continue to leverage the Web for a larger
portion of their transactions and activities, the need to apply traditional
mainframe operational standards becomes more imperative in n-tier/Web-
based Internet environments. This section contains the following chapters.
Chapter 50, “Assessing a Data Administrative Program,” examines con-
siderations in selecting a suitable data administrative approach for an
organization based on techniques and tools.
Chapter 51, “Managing Database Backup and Recovery,” discusses how
to invest in a sound database backup and recovery process to protect cor-
porate data. This involves examining the degrees of recoverability required
by the business, fault tolerance alternatives, virus infiltration, and unau-
thorized tampering through the Internet.
Chapter 52, “Advanced Database Compression,” examines techniques
for reducing data storage requirements by reducing the physical footprint
of stored data.
Chapter 53, “How to Handle Data Loss and Backup,” examines the oper-
ation of backup and recovery plans as part of a wider contingency or disas-
ter recovery plan.
