SQL Fundamentals #1: SQL Data Definition

Last year in college , I had the opportunity to dive deep into SQL. The course was made even more exciting by an amazing instructor . Fast forward to today, and I regularly use SQL in my backend development work with PHP. Today, I felt the need to refresh my SQL knowledge a bit, and that's why I've put together three posts aimed at helping beginners grasp the fundamentals of SQL.

Understanding Relational Databases

Let's Begin with the Basics: What Is a Database?

Simply put, a database is like a digital warehouse where you store large amounts of data. When you work on projects that involve data, you need a place to keep that data organized and accessible, and that's where databases come into play.

Exploring Different Types of Databases

When it comes to databases, there are two primary types to consider: relational and non-relational.

Relational Databases: Structured Like Tables

Think of a relational database as a collection of neatly organized tables, somewhat like rows and columns in an Excel spreadsheet. Each table represents a specific type of information, and these tables are interconnected through shared attributes. It's similar to a well-organized library catalog where you can find books by author, title, or genre.

Key Points:

Tables with rows and columns.

Data is neatly structured, much like a library catalog.

You use a structured query language (SQL) to interact with it.

Ideal for handling structured data with complex relationships.

Non-Relational Databases: Flexibility in Containers

Now, imagine a non-relational database as a collection of flexible containers, more like bins or boxes. Each container holds data, but they don't have to adhere to a fixed format. It's like managing a diverse collection of items in various boxes without strict rules. This flexibility is incredibly useful when dealing with unstructured or rapidly changing data, like social media posts or sensor readings.

Key Points:

Data can be stored in diverse formats.

There's no rigid structure; adaptability is the name of the game.

Non-relational databases (often called NoSQL databases) are commonly used.

Ideal for handling unstructured or dynamic data.

Now, Let's Dive into SQL:

SQL is a :

Data Definition language ( what todays post is all about )

Data Manipulation language

Data Query language

Task: Building and Interacting with a Bookstore Database

Setting Up the Database

Our first step in creating a bookstore database is to establish it. You can achieve this with a straightforward SQL command:

CREATE DATABASE bookstoreDB;

SQL Data Definition

As the name suggests, this step is all about defining your tables. By the end of this phase, your database and the tables within it are created and ready for action.

1 - Introducing the 'Books' Table

A bookstore is all about its collection of books, so our 'bookstoreDB' needs a place to store them. We'll call this place the 'books' table. Here's how you create it:

CREATE TABLE books ( -- Don't worry, we'll fill this in soon! );

Now, each book has its own set of unique details, including titles, authors, genres, publication years, and prices. These details will become the columns in our 'books' table, ensuring that every book can be fully described.

Now that we have the plan, let's create our 'books' table with all these attributes:

CREATE TABLE books ( title VARCHAR(40), author VARCHAR(40), genre VARCHAR(40), publishedYear DATE, price INT(10) );

With this structure in place, our bookstore database is ready to house a world of books.

2 - Making Changes to the Table

Sometimes, you might need to modify a table you've created in your database. Whether it's correcting an error during table creation, renaming the table, or adding/removing columns, these changes are made using the 'ALTER TABLE' command.

For instance, if you want to rename your 'books' table:

ALTER TABLE books RENAME TO books_table;

If you want to add a new column:

ALTER TABLE books ADD COLUMN description VARCHAR(100);

Or, if you need to delete a column:

ALTER TABLE books DROP COLUMN title;

3 - Dropping the Table

Finally, if you ever want to remove a table you've created in your database, you can do so using the 'DROP TABLE' command:

DROP TABLE books;

To keep this post concise, our next post will delve into the second step, which involves data manipulation. Once our bookstore database is up and running with its tables, we'll explore how to modify and enrich it with new information and data. Stay tuned ...

SQL Injection in RESTful APIs: Identify and Prevent Vulnerabilities

SQL Injection (SQLi) in RESTful APIs: What You Need to Know

RESTful APIs are crucial for modern applications, enabling seamless communication between systems. However, this convenience comes with risks, one of the most common being SQL Injection (SQLi). In this blog, we’ll explore what SQLi is, its impact on APIs, and how to prevent it, complete with a practical coding example to bolster your understanding.

What Is SQL Injection?

SQL Injection is a cyberattack where an attacker injects malicious SQL statements into input fields, exploiting vulnerabilities in an application's database query execution. When it comes to RESTful APIs, SQLi typically targets endpoints that interact with databases.

How Does SQL Injection Affect RESTful APIs?

RESTful APIs are often exposed to public networks, making them prime targets. Attackers exploit insecure endpoints to:

Access or manipulate sensitive data.

Delete or corrupt databases.

Bypass authentication mechanisms.

Example of a Vulnerable API Endpoint

Consider an API endpoint for retrieving user details based on their ID:

from flask import Flask, request import sqlite3

app = Flask(name)

@app.route('/user', methods=['GET']) def get_user(): user_id = request.args.get('id') conn = sqlite3.connect('database.db') cursor = conn.cursor() query = f"SELECT * FROM users WHERE id = {user_id}" # Vulnerable to SQLi cursor.execute(query) result = cursor.fetchone() return {'user': result}, 200

if name == 'main': app.run(debug=True)

Here, the endpoint directly embeds user input (user_id) into the SQL query without validation, making it vulnerable to SQL Injection.

Secure API Endpoint Against SQLi

To prevent SQLi, always use parameterized queries:

@app.route('/user', methods=['GET']) def get_user(): user_id = request.args.get('id') conn = sqlite3.connect('database.db') cursor = conn.cursor() query = "SELECT * FROM users WHERE id = ?" cursor.execute(query, (user_id,)) result = cursor.fetchone() return {'user': result}, 200

In this approach, the user input is sanitized, eliminating the risk of malicious SQL execution.

An Overview of Microsoft SQL Server for Database Management

An extensive variety of applications that are associated with data analytics, business intelligence (BI), and transaction processing can be supported by Microsoft SQL Server, which is a relational database management system (RDBMS) that is utilized in corporate information technology environments. Database administrators (DBAs) and other professionals working in information technology are able to operate databases and query the data that they contain thanks to Structured Query Language (SQL), which is a standardized programming language.

SQL is the foundation upon which other relational database management systems (RDBMS) software is constructed. Transact-SQL, sometimes known as T-SQL, is the proprietary query language that Microsoft uses. SQL Server is intrinsically linked to them. Through the use of T-SQL, you are able to connect to a SQL Server instance or database, as well as communicate with other programs and tools.

Inside the architecture of SQL Server: What are the workings of SQL Server?

The basic basis upon which SQL Server is built is a table structure that adheres to the row-based model. Through the utilization of this structure, it is possible to establish connections between data items that are not only related but also placed in other tables. The usually necessary practice of storing data in many locations inside a database is rendered unnecessary as a result of this. In order to ensure that the data is accurate, the relational model also has the capability of providing relative integrity as well as additional integrity requirements.

The execution of database transactions is made more trustworthy by these checks, which are a component of a more thorough adherence to the concepts of atomicity, consistency, isolation, and durability. In other words, these checks are necessary for a more reliable execution of database transactions. In SQL Server, the Database Engine is the most fundamental component. It is responsible for managing all aspects of data storage, including access, processing, and security. As many as fifty instances of the Database Engine can be installed on a single host machine.

In addition to this, it is made up of a relational engine that processes commands and queries, as well as a storage engine that manages database files, tables, pages, indexes, data buffers, and transactions on the database. A wide range of database items, such as stored procedures, triggers, views, and other objects, are all created and executed by the Database Engine. This engine is responsible for maintaining the database. For the purpose of establishing a connection to Database Engine, it is necessary to have a client library or client tool that is functional in either a graphical user interface or a command-line interface, and that has at least one client library.

It is important to provide information regarding the instance name of the database engine system in order to achieve the establishment of a connection. Additionally, users have the right to choose whether or not they wish to provide information regarding the connection port and the protocol that is used by the network. The SQL Server Operating System, often known as SQLLOS, is situated so that it is subordinate to the Database Engine. It is SQLOS that is responsible for handling lower-level functions. In order to prevent separate versions of the database from being updated in a different manner, these characteristics include memory management, input/output (I/O) management, job scheduling, and data locking.

Above the Database Engine is a network interface layer, which is designed to make the process of exchanging requests and responses with database servers more straight forward. The Tabular Data Stream protocol, which was designed by Microsoft, is utilized and utilized by this layer. The writing of T-SQL statements at the user level, on the other hand, is under the purview of SQL Server database administrators and developers. In addition to a variety of other functions, these statements are utilized for the purpose of constructing and modifying database structures, managing data, implementing security measures, and backing up databases.

Securing SQL Server with its built-in features-

Users are able to update encrypted data without having to decrypt. There are three technologies that are included in the advanced security features that are supported in all editions of Microsoft SQL Server beginning with SQL Server 2016 Service Pack 1. These technologies are row-level security, which allows data access to be controlled at the row level in database tables; dynamic data masking, which automatically hides elements of sensitive data from users who do not have full access privileges; and row-level security.

More key security features of SQL Server include fine-grained auditing, which gathers specific information on database usage for the goal of reporting on regulatory compliance, and transparent data encryption, which encrypts data files that are kept in databases. Both of these capabilities are designed to ensure that sensitive information is protected. Microsoft also provides support for the Transport Layer Security protocol in order to guarantee the security of connections between SQL Server clients and database servers. This is done with the intention of ensuring the safety of the connections. The vast majority of the tools and other functionalities that are offered by Microsoft SQL Server are supported by Azure SQL Database, which is a cloud database service that is built on SQL Server Database Engine.

Moreover, support is provided for additional functionality. Customers have the option of running SQL Server directly on Azure through the use of an alternative approach known as SQL Server on Azure Virtual Machines. Through the use of this technology, the database management system (DBMS) on Windows Server virtual machines that are running on Azure can be configured. For the aim of transferring or extending on-premises SQL Server applications to the cloud, the Virtual Machine (VM) service is optimized. On the other hand, the Azure SQL Database is designed to be utilized in the process of developing new cloud-based applications. Additionally, Microsoft offers a data warehousing solution that is hosted in the cloud and is known as Azure Synapse Analytics.

The Microsoft SQL Server implementation that makes use of massively parallel processing (MPP) is the foundation upon which this service is constructed. Additionally, the MPP version, which was formerly a standalone product called as SQL Server Parallel Data Warehouse, is also available for use on-premises as a component of Microsoft Analytics Platform System. This version was initially produced by Microsoft. PolyBase and other big data technologies are incorporated into this system, which also incorporates the MPP version. There are a number of advanced security measures that are included in each and every edition of Microsoft SQL Server. These features include authentication, authorization, and encryption protocols. A user's identity can be verified by the process of authentication, which is done performed by Windows and SQL Server, in addition to Microsoft Entra ID.

The aim of authentication is to validate the user's identity. The user's capabilities are validated through the process of obtaining authorization. The authorization tools that come pre-installed with SQL Server give users the ability to not only issue permissions but also withdraw them and refuse them. Through the use of these capabilities, users are able to establish security priorities according to their jobs and restrict data access to particular data pieces. The encryption capabilities of SQL Server make it feasible for users to keep confidential information in a secure manner. There is the capability of encrypting both files and sources, and the process of encryption can be carried out with the use of a password, symmetric key, asymmetric key, or a certificate.

The capabilities and services offered by Microsoft SQL Server 2022-

A new edition of SQL Server, known as SQL Server 2022 (16.x). The data virtualization feature is a noteworthy new addition to SQL Server. This feature gives users the ability to query different kinds of data on multiple kinds of data sources using SQL Server. The SQL Server Analysis Services that Microsoft offers have also been enhanced in the version 2022 of SQL Server. The following amendments are included in these updates:

Improvements made to the encryption method for the schema writeoperation. In order to reduce the amount of data source queries that are necessary to produce results, the Horizontal Fusion query execution plan is optimized. Both the analysis of Data Analysis Expressions queries against a DirectQuery data source and the parallel execution of independent storage engine operations against the data source are things that are planned to be executed in parallel.

Power BI models that have DirectQuery connections to Analysis Services models are now supported by SQL Server 2022 along with other models. A number of additional new features that were included in SQL Server 2022 include the following list:

Azure Synapse Link for SQL allows for analytics to be performed in a near-real-time manner over operational data. Integration of object storage within the data platform itself. The Always On and Distributed availability groups are the two types of availability groups. For improved protection of SQL servers, integration with Microsoft Defender for Cloud Apps is required. By utilizing Microsoft Entra authentication, a secure connection may be established to SQL Server. Support for the notion of least privilege with the implementation of granular access control permissions and built-in server roles. Support for system page latch concurrency, Buffer Pool Parallel Scan, enhanced columnstore segment elimination, thread management, and reduced buffer pool I/O promotions are some of the updates that have been implemented to facilitate performance enhancements. 

Improvements in the performance of existing workloads can be achieved through the implementation of intelligent query processing features. Azure extensions that simplify management, server memory calculations and recommendations, snapshot backup support, Extensible Markup Language compression, and asynchronous auto update statistics concurrency are some of the features and capabilities that are included.

Additionally, SQL Server 2022 gives users access to a wide variety of tools, including the following and others:

Azure Data Studio is a tool.

The SQL Server Management Studio application.

The SQL Package.

Code written in Visual Studio.

In order for users to successfully install these features and tools, they are required to utilize the Feature Selection page of the SQL Server Installation Wizard throughout the process of installing SQL Server.

Conclusion-

SQL Server comes with a number of data management, business intelligence, and analytics solutions that are bundled together by Microsoft. SQL Server Analysis Services is an analytical engine that processes data for use in business intelligence and data visualization applications. SQL Server Reporting Services is a service that supports the creation and delivery of business intelligence reports. Also included in the data analysis offerings are R Services and Machine Learning Services, both of which were introduced for the first time in SQL Server 2016.

SQL Server Integration Services, SQL Server Data Quality Services, and SQL Server Master Data Services are all components of Microsoft SQL Server that are devoted to the handling of data. In addition, the database management system (DBMS) comes with two sets of tools for database administrators (DBAs) and developers. These tools are SQL Server Data Tools, which are used for designing databases, and SQL Server Management Studio, which is used for deploying, monitoring, and managing databases.

AI built-in

This new version leverages well-known T-SQL syntax and has AI integrated in, making it easier to construct AI applications and retrieval-augmented generation (RAG) patterns with safe, efficient, and user-friendly vector support. This new feature allows you to create a hybrid AI vector search by combining vectors with your SQL data.

Utilize your company database to create AI apps

Bringing enterprise AI to your data, SQL Server 2025 is a vector database that is enterprise-ready and has integrated security and compliance. DiskANN, a vector search technology that uses disk storage to effectively locate comparable data points in massive datasets, powers its own vector store and index. Accurate data retrieval through semantic searching is made possible by these databases’ effective chunking capability. With the most recent version of SQL Server, you can employ AI models from the ground up thanks to the engine’s flexible AI model administration through Representational State Transfer (REST) interfaces.

Furthermore, extensible, low-code tools provide versatile model interfaces within the SQL engine, backed via T-SQL and external REST APIs, regardless of whether clients are working on data preprocessing, model training, or RAG patterns. By seamlessly integrating with well-known AI frameworks like LangChain, Semantic Kernel, and Entity Framework Core, these tools improve developers’ capacity to design a variety of AI applications.

Top-notch performance and security

In terms of database security and performance, SQL Server 2025 leads the industry. Enhancing credential management, lowering potential vulnerabilities, and offering compliance and auditing features are all made possible via support for Microsoft Entra controlled identities. Outbound authentication support for MSI (Managed Service Identity) for SQL Server supported by Azure Arc is introduced in SQL Server 2025.

Additionally, it is bringing to SQL Server performance and availability improvements that have been thoroughly tested on Microsoft Azure SQL. With improved query optimization and query performance execution in the latest version, you may increase workload performance and decrease troubleshooting. The purpose of Optional Parameter Plan Optimization (OPPO) is to greatly minimize problematic parameter sniffing issues that may arise in workloads and to allow SQL Server to select the best execution plan based on runtime parameter values supplied by the customer.

Secondary replicas with persistent statistics mitigate possible performance decrease by preventing statistics from being lost during a restart or failover. The enhancements to batch mode processing and columnstore indexing further solidify SQL Server’s position as a mission-critical database for analytical workloads in terms of query execution.

Through Transaction ID (TID) Locking and Lock After Qualification (LAQ), optimized locking minimizes blocking for concurrent transactions and lowers lock memory consumption. Customers can improve concurrency, scalability, and uptime for SQL Server applications with this functionality.

Change event streaming for SQL Server offers command query responsibility segregation, real-time intelligence, and real-time application integration with event-driven architectures. New database engine capabilities will be added, enabling near real-time capture and publication of small changes to data and schema to a specified destination, like Azure Event Hubs and Kafka.

Azure Arc and Microsoft Fabric are linked

Designing, overseeing, and administering intricate ETL (Extract, Transform, Load) procedures to move operational data from SQL Server is necessary for integrating all of your data in conventional data warehouse and data lake scenarios. The inability of these conventional techniques to provide real-time data transfer leads to latency, which hinders the development of real-time analytics. In order to satisfy the demands of contemporary analytical workloads, Microsoft Fabric provides comprehensive, integrated, and AI-enhanced data analytics services.
