Common Algorithm Concerns

When we build software, many of us use the same algorithms to solve problems. We might choose a similar method for a quicksort or a lambda validation or a regular expression. For database work, your code for a running total (or other common challenge) is likely very similar to many other people. At least on the same platform. You might solve this differently in SQL Server and Oracle, but for the same type of database, many of us write very similar code.

Actually, for many developers, they copy and paste an answer from SQL Server Central, Stack Overflow, or another site. I'm not sure if I think this is good or bad, as it's a good idea to reuse code if it solves the same problem. If you copy it and don't test it, that's bad. After all, the code might not solve your slightly different problem if you don't check it.

In the modern world, if we built software for our business using an AI assistant, could our company be liable if we knew our competitors were using the same AI service? Is this any different than a human developer performing a copy/paste from SQL Server Central? I don't think it is in many cases, though the same concerns about intellectual property might be present in either case.

The concerns over AI seem murky in some sense, especially as the AI might "generate" code that isn't directly available on some public resource. I do think that this is more of a collusion using a service than an algorithm. Still, in the hyper-connected world, where many of our applications might look to take advantage of some service instead of implementing it ourselves, this could be an issue.

I ran across a piece that discusses a lawsuit about a common pricing algorithm being used by different hotels. In this case, it's not that the developers at different hotels used the same code, but rather that the hotels used the same service from a company, which of course, used the same code for all their customers. Whether you think this is a valid lawsuit or not, this is the type of legal action that others might bring if two competitors ended up using the same AI service and developer very similar code that might behave the same way.

I don't think that AIs (at present) can actually develop new algorithms or solve problems in a new way. Instead they predict the likely solution based on how they've been trained by similar scenarios. In that case, how concerned are we about how getting common solutions in disparate pieces of software? For most of us, I think we've be pleased we have well-tested (hopefully) code that runs efficiently re-used in many places. That would be better for most systems in the world.

What isn't better is if humans become more adept at specifying prompts and producing software without lots of specialized expertise. For many developers that might be average, or even slightly below average, this might cause them concern for the security of their position. With good reason, as labor is one of the most expensive parts of building software.

Ultimately, just as with any other position, the best way to build a safe, secure career, is to continue to build your skills and produce value for your employer. That way it's unlikely any AI will every outperform you.

Enhancing Web Application Performance through Database Optimization: A Comprehensive Study

nai3 from SQLServerCentral

In the contemporary digital landscape, web applications play a pivotal role in delivering services and facilitating interactions between users and businesses. However, the performance of these applications heavily relies on the efficiency of underlying databases. This comprehensive study aims to explore the intricate relationship between database optimization techniques and web application performance enhancement. The study begins by delineating the significance of web application performance and its correlation with database operations. It examines various factors affecting performance, including data retrieval, storage, and processing. Furthermore, it identifies common challenges such as latency, scalability issues, and inefficient query execution. Through an extensive review of the literature, this study evaluates state-of-the-art database optimization methodologies and their applicability to web applications. Techniques such as indexing, query optimization, denormalization, caching mechanisms, and data partitioning are scrutinized, highlighting their potential to mitigate performance bottlenecks. Moreover, the study investigates emerging trends and technologies in database management systems (DBMS), such as NoSQL databases, in-memory databases, and cloud-based solutions. It assesses their suitability for enhancing web application performance, considering factors like data volume, query complexity, and real-time processing requirements.

Pro Encryption in SQL Server 2022: Provide the Highest Level of Protection for Your Data

Additional Articles from SQLServerCentral

This in-depth look at the encryption tools available in SQL Server shows you how to protect data by encrypting it at rest with Transparent Data Encryption (TDE) and in transit with Transport Level Security (TLS). You will know how to add the highest levels of protection for sensitive data using Always Encrypted to encrypt data also in memory and be protected even from users with the highest levels of access to the database. The book demonstrates actions you can take today to start protecting your data without changing any code in your applications, and the steps you can subsequently take to modify your applications to support implementing a gold standard in data protection.

 Yesterday's Question of the Day (by Steve Jones - SSC Editor)

Implementing Change Data Capture

I have a complex environment that uses quite a few SQL Server 2022 servers. We have a powerful SQL Server running Enterprise that hosts most of our transaction data. However, there are remote locations that run Standard, Web, Express, and Express with Advanced Services editions for local collection of data before the data is transferred to our central Enterprise Edition server.

We are considering using Change Data Capture (CDC) to lower the amount of data we transfer from clients. Which editions can we implement this feature on?

Answer: Standard and Enterprise only

Explanation: CDC is an Enterprise and Standard edition feature only. Ref: Data Warehouse Features and Editions - https://learn.microsoft.com/en-us/sql/sql-server/editions-and-components-of-sql-server-2022?view=sql-server-ver16&preserve-view=true#data-warehouse

Backup with Checksum Show No Issues, While DBCC CHECKDB Reports Errors - I took a backup with the CHECKSUM option, which was successful and showed no errors. However, when I restored the same backup, it showed DBCC CHECKDB errors. I want to understand why the checksum did not detect any issues, but DBCC CHECKDB did. What are the issues that a checksum will not detect but DBCC […]
Linked Server Product Name? - Just came across something weird. Was wondering if anyone else has ever seen this.

Can index fragmentation cause the database to enter suspect mode? - My database was in suspect mode, and when I checked using DBCC CHECKDB, it returned errors. As mentioned in the link below, I used the REPAIR_ALLOW_DATA_LOSS option with the DBCC CHECKDB command, but few errors persisted. https://www.stellarinfo.com/support/kb/index.php/article/procedure-to-recover-sql-database-from-suspect-mode Later, I dropped and recreated the indexes. This resolved the issue. My question is whether index fragmentation could […]
