iSeries (AS/400) Data Base Administration I
(Data Description Specifications)
Now Released on Audio CD
Course Code: ADB1
Description
Data Base Administration I is a self-paced, audio based driven course providing
comprehensive, practical training in describing and creating physical and logical
files.
Upon completion you'll be able to:
Use Data Description
Specifications (DDS) to define physical and logical files.
Define alphanumeric
and numeric fields and assign attributes that validate user- entered data, present
the data in edited form, allow input only, output only, or both, and other useful
attributes.
Create a field
reference file that serves as the single-source supplier of field attributes
to other files.
Create files that
allow only one file member, or an unlimited number of file members, and be able
to add, clear, or remove file members.
Create logical
files that concatenate two or more fields into one field and split a field into
smaller fields.
Create files indexed
by one or more fields, permit or restrict duplicate keys, or sequence records
in FIFO or LIFO order.
Create logical
files that join or interleave records from two or more files and select records
based on the value of one or more fields.
Specify how a file's
access path should be maintained by the system for performance.
Use OS/400 CL commands
to display descriptions of files, fields, and the relationships between physical
and logical files.
