This blog post describes how you can convert your client database running with a
single-byte character set database, WE8ISO8859P1, to a Unicode Character Database (UCD),
AL32UTF8, by using the Oracle Data Migration Assistant for Unicode (DMU) tool.
This post describes Oracle® Application Express (APEX) and Oracle REST Data
Services (ORDS), including the steps to install APEX and install and configure
ORDS. Typically, database administrators (DBAs) carry out both of these tasks.
