All About Microservices Architecture **Microservices Architecture** is an approach to software development where a large application is broken down into smaller, independent services that can operate and be deployed independently. Instead of building a monolithic application, which is a single, tightly-integrated unit, microservices architecture divides the functionality into separate services that communicate with each other through well-defined APIs (Application Programming Interfaces). Key characteristics of microservices architecture include: 1. **Modularity:** Each microservice represents a specific business capability and can be developed, deployed, and scaled independently. 2. **Independence:** Microservices are autonomous, meaning they can be developed, deployed, and updated without affecting the entire system. This independence allows for faster development cycles. 3. **Scalability:** Since each service is independent, you can scale only the specific microservices that require

What is Natural Language Processing (NLP) ? Natural Language Processing (NLP)* is a field of artificial intelligence (AI) that focuses on the interaction between computers and humans using natural language. It involves the development of algorithms and models that enable computers to understand, interpret, and generate human language. Here are key aspects of NLP: 1. *Text Understanding:* NLP systems aim to comprehend the meaning of written or spoken language. This involves tasks such as text classification, sentiment analysis, and named entity recognition. 2. *Speech Recognition:* NLP extends to processing spoken language, converting audio signals into text. This technology is used in voice assistants, transcription services, and more. 3. *Language Generation:* NLP systems can generate human-like text. This is employed in chatbots, language translation services, and content generation. 4. *Machine Translation:* NLP is fundamental to machine translation systems that enable the automatic

Rules are made to be broken but are also made for a reason. Our ‘go to’ is the widely known ‘rule of thirds’ and is considered in the majority of our intentional compositions. But what other compositions do we use? 1 - Golden Spiral : Based on the Fibonacci numbers, this composition uses arcs infinitely resembling a spiral shape, which can be used to create balanced and aesthetically pleasing photos. 2 - Cross : A simple but harmonious composition using two lines, creating a midsection crosshair with the subject in the center of the frame. 3 - Tunnel : Similar to ‘leading lines’ tunnel composition is used to draw your eye to a subject using depth. 4 - L Shape : The L-shape composition appears when the elements create the “L” shape which can be (and often is) multiplied. The static horizontal and vertical lines this kind of composition presents create the feeling of rest, stillness, and harmony. 5 - S Curve : The curved lines in an S-curve composition add a sense of movement to an other

What is Concurrency Control? Concurrency Control in Database Management System is a procedure of managing simultaneous operations without conflicting with each other. It ensures that Database transactions are performed concurrently and accurately to produce correct results without violating data integrity of the respective Database. Concurrent access is quite easy if all users are just reading data. There is no way they can interfere with one another. Though for any practical Database, it would have a mix of READ and WRITE operations and hence the concurrency is a challenge. DBMS Concurrency Control is used to address such conflicts, which mostly occur with a multi-user system. Therefore, Concurrency Control is the most important element for proper functioning of a Database Management System where two or more database transactions are executed simultaneously, which require access to the same data. Potential problems of Concurrency Here, are some issues which you will likely to face wh

Web database The Web-based database management system is one of the essential parts of DBMS and is used to store web application data. A web-based Database management system is used to handle those databases that are having data regarding E-commerce, E-business, blogs, e-mail, and other online applications. While many DBMS sellers are working for providing a proprietary database for connectivity solutions with the Web, the majority of the organizations necessitate a more general way out to prevent them from being tied into a single technology. Here are the lists of some of the most significant necessities for the database integration applications within the Web. These requirements are standards and not fully attainable at present. There is no ranking of orders, and so the requirements are as follows: The ability and right to use valuable corporate data in a fully secured manner. Provides data and vendor's autonomous connectivity that allows freedom of choice in selecting the DBMS f

SQL Injection The SQL Injection is a code penetration technique that might cause loss to our database. It is one of the most practiced web hacking techniques to place malicious code in SQL statements, via webpage input. SQL injection can be used to manipulate the application's web server by malicious users. SQL injection generally occurs when we ask a user to input their username/userID. Instead of a name or ID, the user gives us an SQL statement that we will unknowingly run on our database. For Example - we create a SELECT statement by adding a variable "demoUserID" to select a string. The variable will be fetched from user input (getRequestString). demoUserI = getrequestString("UserId"); demoSQL = "SELECT * FROM users WHERE UserId =" +demoUserId; Types of SQL injection attacks SQL injections can do more harm other than passing the login algorithms. Some of the SQL injection attacks include: Updating, deleting, and inserting the data: An attack can mo
