ADOdb and PDO are both database abstraction libraries for PHP that allow developers to write database-independent code. ADOdb hides database specifics and provides a consistent API, additional functions, and better performance compared to PDO. Both libraries establish database connections using object-oriented methods and execute SQL queries by iterating through result sets. While PDO focuses only on basic data access and prepared statements, ADOdb offers more advanced features like pagination, blob handling, and error handling.

PDO Basics - PHPMelb 2014
A quick overview of PHP's PDO. Aimed at beginners and those who use too many ORMs. This was done as a lightening talk at the PHP Melbourne User Group January 2014.
PHP - PDO Objects
This document discusses PHP Data Objects (PDO) for connecting to and interacting with databases. PDO requires PHP version 5 and uses two main objects - the PDO object represents a database connection, and PDOStatement represents prepared statements and result sets. Methods like prepare(), execute(), fetch(), and fetchAll() allow preparing and executing statements as well as retrieving result sets. Examples demonstrate using PDO for common SQL statements like SELECT, INSERT, UPDATE, and DELETE.

Without clear understanding and strategy, Node error handling might be the Achilles heel of your app – its unique single-threaded execution model and loose types raise challenges that don’t exist in any other frameworks. Node by itself doesn’t provide patterns for critical paths like where to put error handling code, even worst it suggest patterns that were rejected by the community like passing errors in callbacks.
It covers topics like promises, generators, callbacks, unhandled exceptions, APM products, testing errors, operational errors vs development errors and much more
Database Security
Database security aims to protect data from unauthorized access through various security controls. This includes restricting access (secrecy), ensuring data integrity, and maintaining data availability. Common threats include accidental issues like hardware/software errors and natural disasters, as well as deliberate actions by authorized or unauthorized users. Microsoft Access provides security features like user accounts, permissions, and database passwords to control access and protect data.
Database administrator
A database administrator is responsible for installing, configuring, upgrading, administering, monitoring and maintaining databases. Key responsibilities include database design, performance and capacity issues, data replication, and table maintenance. DBAs ensure proper data organization and management through their skills in SQL, database design, and knowledge of database management systems and operating systems. There are several types of DBAs based on their specific roles like system DBA, database architect, and data warehouse administrator.

Solutions for bi-directional Integration between Oracle RDMBS & Apache Kafka
Apache Kafka is a popular distributed streaming data platform. A Kafka cluster stores streams of records (messages) in categories called topics. It is the architectural backbone of modern data analytics. Data flowing into Kafka often originates from native data streams such as social media streams, telemetry data, financial transactions and many others. But these data streams only contain part of the information. A lot of data necessary in stream processing is stored in traditional systems backed by relational databases. To implement new and modern, real-time solutions, an up-to-date view of that information is needed. So how do we make sure that information can flow between the RDMBS and Kafka, so that changes are available in Kafka as soon as possible in near-real-time? It this session, we present different approaches for integrating relational databases with Kafka, such as Kafka Connect, Oracle GoldenGate and bridging Kafka with Oracle Advanced Queuing (AQ).

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
