Oracle Database Administration from Zero to Hero - Practice - Using Table Compression

The video tutorial explores basic and advanced compression techniques in Oracle databases. It demonstrates creating tables with different compression types and examines their impact on disk space. The tutorial highlights the role of data duplication in compression efficiency and compares traditional insert statements with direct path loading. Key conclusions include the dependency of basic compression on data duplication and the effectiveness of advanced compression with both insert methods.

What is the primary focus of the initial setup in the practice?

• Creating a backup of the database

• Implementing basic and advanced compression techniques

• Analyzing network performance

• Setting up user permissions

Which table is not compressed in the initial setup?

• CUST Source

• Cast C Compressed

• Cast A Compressed

• Cast B Compressed

What is the effect of basic compression when using normal insert statements?

• It only works with advanced compression

• It significantly reduces table size

• It has no effect on table size

• It increases table size

How does direct path loading affect basic compression?

• It only works with non-compressed tables

• It has no effect

• It reduces the table size slightly

• It increases the table size

What factor significantly influences the efficiency of basic compression?

• The database version

• The amount of repeated data

• The type of data

• The number of columns

How does advanced compression perform with normal insert statements compared to basic compression?

• It does not work with normal insert statements

• It performs worse

• It performs the same

• It performs better

What is the conclusion regarding advanced compression with direct path loading?

• It only works with non-compressed tables

• It does not work with direct path loading

• It has the same effect as basic compression

• It is less effective than basic compression
