The main constituent of any database is its tables, in order to make data accessibility custom there is concept of Views in other words we can say that with the help of Views of a table we can restrict any user to access only that data which is supposed to be accessed by him. Now on the basis of characteristic and features of the views we can distinguish between Views and Materialized Views. In this article, we will discuss the important differences between Views and Materialized Views in SQL. But before, let’s have look into the basics of views and ... Read More
Static SQLStatic SQL refers to those SQL statements which are fixed and can be hard coded into the application. As static sqls are fixed queries, these statements can be analyzed and optimized and do not require any specific handling for security purposes.Dynamic SQLDynamic SQL refers to those SQL statements which are generated dynamically based on user's input and run in the application. Dynamic Sqls helps to develop general and flexible applications. Dynamic SQL may need more permissions and security handling and a malicious user can create dangerous code as well.Following are some of the important differences between Static Routing and ...

Embedded SQL Embedded SQL is a method that combines SQL with a high−level programming language's features. It enables programmers to put SQL statements right into the source code files used to set up an application. Database operations may be carried out effortlessly by developers by adding SQL statements to the application code. The source code files having embedded SQL statements should be preprocessed before compilation because of the issue of interpretation of SQL statements by the high−level programming languages in embedded SQL. The terms EXEC SQL and END_EXEC must be used before and after each SQL statement in the source ... Read More
Embedded SQL is a powerful method that allows the integration of high−level programming languages with database management systems (DBMS). It acts as a bridge between applications and databases which helps in data manipulation and communication. Various database management systems offer embedded SQL, giving developers the freedom to select the one that best serves their requirements. Popular DBMS that support Embedded SQL are Altibase, IBM Db2, Microsoft SQL Server, Mimer SQL, Oracle Database, PostgreSQL, and SAP Sybase. Need of Embedded SQL The goal to make database interactions simpler for application developers and end users determines the demand for embedded SQL. ... Read More
Structured Query Language (SQL) is a programming language. SQL is used to manage data stored in a relational database. SQL has the ability to nest queries. A nested query is a query within another query. A nested query allows for more complex and specific data retrieval. In this article, we will discuss nested queries in SQL, their syntax, and examples. Nested Query In SQL, a nested query involves a query that is placed within another query. The output of the inner query is used by the outer query. A nested query has two SELECT statements: one for the inner query ... Read More
Small businesses, due to their lack of cybersecurity resources, have become an easy target for cybercriminals. Start-ups in most of the cases have weak security measures, which leaves them vulnerable to ransomware, data breaches, and other online dangers. This increasing danger highlights how important it is for small businesses to recognize their risks and take preventative measures to safeguard their operations.Why Small Businesses are Prime Targets for Cyberattacks?In this section, I have listed down some of the prime reasons why small businesses become victims of cyberattacks - Absence of Strict Security MeasuresSmall businesses may have limited resources, making it difficult to ...

In this article we will learn to insert styled text into a JTextPane component in Java. The JTextPane component is a versatile text editor that supports rich text features, including the ability to style text with different fonts, colors, and sizes. By leveraging the StyledDocument and Style classes, you can insert styled text dynamically into a JTextPane using Java Swing. Insert styled text in a JTextPane component using the SimpleAttributeSet and StyleConstants classes. With that, we will also use StyledDocument. Java Swing The Swing API is a collection of flexible GUI components designed to simplify the development of Java-based front-end ... Read More
In this article, we will learn to calculate the product of the unique prime factors of a given number using Java. Prime factorization plays a crucial role in many mathematical and computational problems, and understanding how to work with prime factors can help you solve complex challenges efficiently. Problem Statement Given a positive integer n, the task is to find the product of the unique prime factors of n. The objective is to calculate the product of all distinct prime factors of n that divide it exactly. Input 68 Output 34 Since the unique prime factors of 68 are 2 ... Read More
In this article, we will learn to calculate the GCD of more than two numbers in Java. We will discuss two approaches, the recursive method and an optimized approach using the Euclidean algorithm. The Greatest Common Divisor (GCD) of two or more integers is the largest integer that divides all the numbers without leaving a remainder. When it comes to an array of numbers, finding the GCD means determining the GCD of all the elements in the array. Problem Statement Given an array of integers, find the GCD of all the elements.Example −Input {7, 49, 177, 105, 119, 42} Output ... Read More
