Guess who couldn't resist making yet another moodboard... 🥲 This time, one for y'all Q lovers, hehe.
Finding a screenshot that wasn't sad brown/gray (Skyfall and Spectre) or too dark with a bad looking Q (NTTD) wasn't easy... thanks @prismatic-bell for enhancing the colors on the one I ended up choosing ♥️
Oh, and yes, bottom left picture is by me.

I tried out SQL Murder Mystery !
Someone in my post about sql resources recommended it thank you so much!
It’s a short little web game that helps you get familiar with SQL. You have to search through the database for clues and investigate a murder basically.
I found it really fun ☜(˚▽˚)☞
Cute game. Would recommend.

SQL Injection Attacks:
Understanding the Risks and Implementing Prevention Measures
Introduction:
In today's interconnected world, where data is a valuable asset, protecting the integrity and security of databases is critical. SQL injection attacks are a significant threat that database administrators and developers face. These attacks take advantage of vulnerabilities in web applications to manipulate the underlying SQL queries, potentially resulting in unauthorized access, data breaches, and compromised systems. Understanding the risks associated with SQL injection attacks and putting effective prevention measures in place are critical for protecting sensitive data. In this article, we will look into the specifics of SQL injection attacks, as well as their potential consequences and preventive measures.
What exactly is SQL Injection?
SQL injection is a technique used by attackers to insert malicious SQL code into a database query in an application, allowing them to manipulate the query's behavior. Attackers can circumvent authentication mechanisms, access unauthorized data, modify or delete records, and even take control of the entire database server by taking advantage of inadequate input validation and sanitization practices.
SQL Injection Attack Risks and Consequences:
a. Unauthorized Access: SQL injection vulnerabilities can be used by attackers to bypass login systems and gain unauthorized access to sensitive data, user accounts, or administrative privileges.
b. Data Breach: SQL injection attacks can expose sensitive data, such as personally identifiable information (PII), financial data, or intellectual property. This can have serious legal, financial, and reputational ramifications for organizations.
c. Database Manipulation: Attackers can change, delete, or manipulate data in a database, potentially resulting in data corruption, operational disruptions, or financial losses.
d. Denial of Service: SQL injection attacks can cause database servers to become overloaded, resulting in system crashes or slowdowns and making the application inaccessible to legitimate users.
Preventive measures include:
a. Input Validation and Sanitization: Enforce strict input validation by validating and sanitizing user input before it is used in SQL queries. Use parameterized queries or prepared statements to ensure code and data separation, preventing malicious code injection.
b. Least Privilege Principle: Assign database accounts the bare minimum of privileges. Reduce the potential impact of a successful SQL injection attack by restricting access and limiting the permissions granted to application accounts.
c. Web Application Firewalls (WAF): Use WAFs that specialize in detecting and preventing SQL injection. These security solutions can detect and prevent malicious SQL queries from reaching the database server.
d. Regular Patching and Updates: Maintain all software, frameworks, and libraries with the most recent security patches. This contributes to addressing known vulnerabilities that attackers could exploit.
e. Educate and Train Developers: Raise developer awareness of the risks and consequences of SQL injection attacks. Teach them secure coding techniques, with an emphasis on input validation, parameterized queries, and proper error handling techniques.
f. Security Audits and Penetration Testing: Perform regular security audits and penetration testing to identify and remediate potential SQL injection vulnerabilities. Engage ethical hackers or security professionals to assess the security posture of the application.
Conclusion:
SQL injection attacks pose a significant risk to database security and integrity, potentially resulting in unauthorized access, data breaches, and compromised systems. Understanding the risks of SQL injection and implementing strong prevention measures are critical for organizations looking to safeguard their valuable data assets. Developers and administrators can mitigate risks and stay one step ahead of malicious actors by implementing secure coding practices, deploying web application firewalls, and conducting regular security audits. Remember that prevention is the key to preventing SQL injection attacks and ensuring the security of your database systems.

Today, at work, I created dynamic SQL queries in PHP so that I could retrieve credit hours and cost information for whatever courses were selected in a financial calculator we're building.
This was a challenge because my experience with PHP is limited and with SQL it is non-existent. The SQL part, ironically, was a little easier than figuring out how to integrate it with my php using the classes I was given to interact with my database.
However, it is a challenge I overcame! I had to ask my boss for specifics on how the class constructed the queries and how I should format the parameters but he was very helpful and I was able to get it done right before he left for the day.

Data Analytics Course with SQL
What is SQL? SQL course
Although Structured Query Language (SQL) itself is not a programming language, it is known to many as a programming language. SQL is a sub-language used in any database environment. With SQL, operations can only be performed on the database; Databases are used to add data to systems, modify data, retrieve data, and query data.
Importance of Data Analytics with SQL courses
By participating in the data analytics with SQL course designed by Innab Business School with special care and expert support, you will have one of the most sought-after qualifications of our time without any prior coding knowledge, and you will be one of the most sought-after employees on the labor market. In modern times, data is considered the most valuable asset of companies. Businesses with more data are able to more effectively minimize risks, whether in their internal management or in customer and competitor-oriented decisions. Companies are innovating more every day to make the growing data in their internal ERPs readable and make the right decisions. A structured language was needed to store data, manage it, process it and make various decisions, and for this purpose SQL was created.

Guys, I did
I did the hardest part - got the SQL working. The Google bar charts are now showing data!!!!!!
I sat down and was like "No breakfast or Stardew Valley until I get AT LEAST the hard bit done"
Started at 8:30am and it is now 11:34am and I did it.
What I also did was did a 'cry for help' to the Lead Developer on the CSS styling of the Google bar charts
CSS sucks sometimes!
Tumblr media
Update!!
Lead Developer also doesn't know how to fix the CSS issue!
He doesn't know if it's a Google Charts API issue of a Bootstrap 5 issue!
All he said "Well done" hehe!!! and that I completed the task and he would contact me later to put the page up live!
Another successful task! Now I can focus on my night coding class homework~!
Yay to me!
Lead Developer: It’s an easy task, like I’ve shown you here. Should be done by tomorrow preferably. Just move this chart under the rest and then add a new chart with new information. You think you can do it? 😊
Me: Heck yeah! Seems easy enough! 😎
Me, 6 days later: why is the Bootstrap styling not working? Why SQL query not working? Too scared to ask for help now since it’s going to 7 days since I got given the task.
(I’ll present back to him what I have tomorrow and he’ll have to help me from there)
