Imagine finding one book in a library of 10 million… with no catalogue. You wouldn’t start at shelf one every time. But that’s exactly what a database does when you don’t create an index. Without an index, it performs a full table scan —checking every row until it finds a match. An index doesn’t store more data. It simply tells the database where to look. That’s the difference between milliseconds and seconds. Before calling your query slow,ask yourself: Did you give your database a map? #DatabaseSeries #BackendEngineering #Indexing #SystemDesign #TechExplained

🛑 Your database is for data, not for JPEGs. Stop storing binary files in your SQL tables. ❌ What the Junior Misses: The Junior converts the image into a Base64 string or uses a BLOB (Binary Large Object) type and stuffs it directly into a table row. 1️⃣ The Failure: Databases are optimized for structured data, not heavy files. 2️⃣ The Cost: Your database backups become massive (taking hours instead of minutes), RAM is wasted caching images instead of queries, and you pay "Database Pricing" (expensive SSDs) for storage that could be on cheap disks. ✅ How the Senior Thinks: The Senior separates Metadata from Content. 1️⃣ Object Storage: Upload the actual file to a dedicated service like AWS S3, Google Cloud Storage, or Azure Blob. These are cheap, infinitely scalable, and designed for heavy files. 2️⃣ Database Reference: In your SQL table, you only store the URL or the File Path string (e.g., s3://users/avatar_123.jpg). 3️⃣ CDN (Bonus): Serve the image through a Content Delivery Network so the user downloads it from a server near them, not your main database. Keep your database lean. If you can't query it (like pixels in an image), it doesn't belong in the database. #systemdesign #softwareengineering

I built a note-taking app that supports text-to-speech, auto-playing notes, and AI writing assistant features. Tekno Notebook works offline and features text-to-speech, auto-playing notes, and an AI assistant powered by open-source and local AI models. So I'm happy to make it free for students and anyone who enjoys taking notes

Been experimenting with NotebookLM and it’s a really interesting way to organize information. Upload your docs, notes, or transcripts and it turns them into something you can actually interact with and ask questions about. For people building systems, doing research, or managing lots of info… this will help drastically with for all learning styles.

▶️ The execution of a SQL query is a multi-step internal process managed by the database management system (DBMS), which involves parsing, optimizing, and running the query based on a specific logical order of operations. ▶️ The Internal Process When a query is submitted to the database, it goes through several steps: ➡️ Parser/Analyzer: The DBMS first scans the query to ensure it follows the correct syntax and breaks it down into logical components. ➡️ Query Optimizer: This component is the "brain" of the process. It analyzes different ways to access the data and decides the most efficient plan (the "execution plan") to retrieve the results with minimum resource usage (CPU, memory, I/O). It considers available indexes, table statistics, and join methods. ➡️ Execution Engine: The engine then executes the finalized plan step by step, requesting data from the storage engine and processing it into the final result set. ➡️ Storage Engine: This underlying layer is responsible for the actual reading from and writing to disk or memory. ▶️ The Logical Order of Clauses - The standard logical order of execution for a SELECT query is: 1️⃣ FROM and JOIN: Identifying the tables involved and combining rows from them to form a working dataset. This is the very first step. 2️⃣ WHERE: The rows in the working dataset are then filtered based on the conditions specified in the WHERE clause. This limits the data before computationally intensive operations. 3️⃣ GROUP BY: If present, the filtered data is organized into groups based on the values in one or more columns, allowing aggregate functions (like COUNT, SUM, AVG) to be applied to each group. 4️⃣ HAVING: This clause filters the grouped data based on conditions involving aggregate functions, much like WHERE filters individual rows. 5️⃣ SELECT: It determines which columns, expressions, or calculations are included in the final output. 6️⃣ DISTINCT: If specified, duplicate rows are removed from the result set. 7️⃣ ORDER BY: The final result set is sorted according to the specified columns in ascending (ASC) or descending (DESC) order. 8️⃣ LIMIT / OFFSET: The fin #sqltips #sqlquery #sqldeveloper #sqlquery #execution
