Q & A

What is the purpose of the 'product setup' mentioned in the Tech mining video?

The 'product setup' is designed to manage product information and includes two pages: 'products' and 'product details', allowing users to view and manage product information in different views.

How many different views are available on the main products page?

There are three different views available on the main products page: icon, report, and details.

What is the role of the 'product details' page?

The 'product details' page is used to add, modify, and delete product information.

What is a Blob column and why is it used in the product info table?

A Blob column uses the binary large object data type to store up to 4GB of data, such as digitized information like images, audio, and video files. It is used in the product info table to handle images for each product.

What is a MIME type and how is it related to the product info table?

A MIME type is a standard that indicates the nature and format of a document, file, or assortment of bytes. It is used in the product info table to identify the format of the file stored in the Blob column.

What is the significance of the 'image last update' column in the product info table?

The 'image last update' column is used to store the last update date of the image Blob, helping to keep track of when the product image was last modified.

How can the Oracle Apex application incorporate a stylesheet into a page?

The application can incorporate a stylesheet by following the steps outlined in the script, which includes modifying the page properties and using CSS rules to style the page elements.

What is the primary key column in the product info table and why is it important?

The primary key column is 'product ID', which uniquely identifies a product. It is important because it ensures each product can be distinctly recognized and referenced in the database.

How can images be made to appear in the interactive report without being affected by the 'escaped' property?

To make images appear in the interactive report, the 'escaped' property for each report column should be turned off, as it prevents cross-site scripting attacks but also hides images.

What substitution strings are used to forward a value to the target page in an interactive report?

Special substitution strings enclosed in number symbols (e.g., #PRODUCT_ID#) are used to forward a value to the target page in an interactive report.

How can the appearance of the report be customized by overriding built-in styles?

The appearance of the report can be customized by modifying the table tag with complete HTML code and using CSS rules to style the table and its subordinate elements.
