Oracle APEX Low-Code Authentication and Authorization

Oracle APEX includes user security features rooted firmly within Oracle. These features permit developers to list users, add users, assign user’s permissions/roles, and removing a user. When promoting a low-code and secure application, trusting then using Oracle’s security for user authentication and authorization will save time, effort, and costs. You gain the additional benefit of drawing on decades of Oracle’s experience in user security. I am presenting this article in two parts. Together, these articles examines the APEX_ACL and APEX_UTIL packages and several public views including APEX_APPL_ACL_USER, and APEX_WORKSPACE_USERS.

Oracle PL/SQL Storing Large Objects on AWS S3

Storing large files in an Oracle database can be expensive and cumbersome. The expense comes from the size of the on-line disk storage and the efforts to run backups with archive logs. Oracle Cloud Infrastructure introduced a REST API for large object storage (multi-media files, etc.) This feature has been available with Amazon Web Services (AWS) for years. I wrote and published an API for AWS S3 storage using PL/SQL in 2016 and 2017. With AWS S3, a development team can reliably store binary large objects (BLOB / multimedia files) securely and cost effectively. In this article, I’ll explore the advantages and updates I have made to the AWS S3 package.

Querying JSON with Oracle SQL

Querying JSON data within Oracle improves year by year. For nearly 50 years, Oracle has been a relational database relying on linking data between tables. JSON often contains arrays of data within elements. Querying JSON successfully relies on more than knowing syntax, but also understanding how the data structures differ. We will explore SQL select statements to parse JSON data including arrays. You’ll need to utilize these skills while developing Application Programming Interfaces (API).

APEX Debug Messages – Standardize error collection, debugging and trace

Abstract In the releases of Oracle since 12.1, the Oracle APEX team has enhanced the features and benefits of APEX_DEBUG_MESSAGES. For a couple of years, we have been able to use Oracle Application Express (APEX) debug tools to replace logger and other ad-hoc error trapping tools. The benefits include: Improved portability of code; Streamlining the …
