In my 18+ years of tech experience, I’ve faced ransomware attacks twice, which pushed me to fortify my data, tech and make more informed decisions about cybersecurity. Ransomware attacks are one of the most dangerous and costly cybersecurity threats today. This type of malware encrypts your files, rendering them inaccessible until you pay a ransom…
As a Tech Advisor, I’m often asked how to protect against online scams. With 18+ years of tech experience, I know that online phishing scams are increasingly common, and staying informed is your best defense. Phishing scams are one of the most common cyber threats today, targeting individuals and organizations alike. Attackers use fraudulent emails,…
In over 18 years of building enterprise applications, one critical concept has faded into the background with the rise of NoSQL databases and non-computer science developers making database design decisions. I’m talking about database design principles—Normalization and Denormalization—key to maximizing data integrity and performance. Both approaches serve distinct purposes, depending on whether your database is…
With over 18 years of enterprise-building experience, I know: no matter how much you’ve optimized your data, database-specific optimizations are always on the table. As your database scales, ensuring strong query performance is crucial, but you can push it even further by leveraging optimizer hints and database-specific enhancements. Modern relational database management systems (RDBMS) come…
With 18+ years of experience building enterprise tech solutions, I know: as data volumes grow, scaling traditional relational databases can quickly become a bottleneck—you must get creative to manage them at scale. Here’s the concept Sharding comes in—an essential partitioning technique that horizontally scales databases by distributing data across multiple servers or partitions, known as…
With 18+ years of experience in building enterprise applications, I assert: when working with databases, optimizing your queries is crucial for ensuring efficient data retrieval and processing. This tech concept, explores few effective strategies for handling query limitations, including pagination, window functions, and additional optimization techniques to enhance performance. 1. Efficient Pagination Fetching large result…
In my 18+ years of building enterprise applications, I have encountered numerous situations where improper management of concurrency and locking in a database has led to failures in data integrity and performance. Proper handling of database concurrency and locking mechanism helps prevent issues like contention and deadlocks. In this tech concept, we will explore best…
Building tech solutions for over 18 years, I constantly demanded: database and development teams select the right data types in system design—it’s crucial for optimizing storage efficiency and performance. Efficient data types not only save disk space but also enhance database query execution speeds and improve indexing. In this tech concept, we’ll explore best practices…
Building tech solutions for over 18 years, I have relentlessly demanded that our database team prioritize, efficient use of transactions to ensure data integrity and maintaining high-performance database systems.
