A Simple Guide to Oracle Application Express (APEX)
If you want to learn more about Oracle Application Express (APEX), you've come to the right place!
What is Oracle Application Express?
Oracle Application Express is the native low code framework of the Oracle Database. Using Application Express, you can easily create modern, responsive, scalable Web applications with minimal effort. With no additional coding, Web apps created with APEX look great on the desktop, tablet or smartphone.
Application Express is a supported feature of the Oracle Database and is included, at no additional cost, with every Oracle Database, both on-premises and in the cloud. There are no additional licensing costs based on the number of developers, applications or end-users. Application Express is also included with every Oracle Database Cloud Service, from the low-priced Oracle Database Exadata Express Cloud Service all the way up to the Oracle Database Exadata Cloud Service.
Why Low Code?
The benefits of low code development are greater productivity in less time at less cost and with greater consistency. Low code frameworks, such as Application Express, leverage powerful components that provide reporting, data visualization, and form controls. This enables an application developer to focus on solving the business problem and delivering superior solutions, with less time and effort spent on mundane and repetitive lower-level coding typically associated with application development.

Step 4. says "Browse your working directory to select and open lab1_script.sql. Where is the 'working directory' ?

Then I created an account in apex.oracle.com then I found myself looking at another list of files but none of them was lab1_script.sql.
I would be very grateful for any help because this is holding up a Proof-of-Concept. Thanks a lot. Barry.
Please see the very first section "Before You Begin" at the beginning of this tutorial. The "working directory" is on your local file system, where you unzipped files.zip.
I hope this helps.
