A fully heterogeneous distributed database system will support different database management systems (DBMS) that may even support different models running under different computer systems.

A database management system (DBMS) is a piece of software used to store and retrieve user data while taking necessary security precautions. It is made up of several programs that manipulate the database.

When an application requests data, the DBMS accepts the request and tells the operating system to give the requested data. A DBMS facilitates the storage and retrieval of data for users and other third-party software in complex systems.

Users can design their own databases using DBMS, depending on their needs. The term "DBMS" refers to both the application programs and the database user. Between the data and the software application, it offers an interface.

A string is a type of data used in programming that is similar to integers and floating point numbers, but it represents text rather than numerical values. It is made up of a string of characters, which can also include spaces and numbers.

As an illustration, the words "hamburger" and "I ate 3 hamburgers" are both strings. If properly specified, even "12345" could be regarded as a string. To make sure that a string is recognized as a string and not a number or variable name, programmers typically have to enclose strings in quotation marks.

int fact(int num);

int main() {

 int num = 5;

 printf("The factorial of %d is %d\n", num, fact(num));

 return 0;

}

// Function definition

int fact(int num) {

 int result = 1;

 for (int i = 1; i <= num; i++) {

   result *= i;

 }

 return result;

}

Explanation:

The fact() function takes an integer as a parameter and calculates the factorial of that number by using a for loop to multiply the numbers from 1 to the given number. It then returns the result of the calculation.

In this example, the main() function calls the fact() function and passes the value 5 as an argument. The fact() function calculates the factorial of 5 and returns the result, which is then printed to the console by the main() function.

To calculate Response time, R.T = Time(at which the process get the cpu for 1st time) - Arrival Time(A.T)

Average Response time =(0+1+2 )/3 = 1second.

Turnaround Time, T.T = Exit time - A.T(Arrival Time) ,So for the SJF, T.T for B = (12-0) = 12 sec.

so, for FIFO, T.T for B = 8 seconds = (8-0) seconds.

What is Shortest Job First in cpu scheduling?

A scheduling strategy known as "shortest task first" chooses the process with the shortest execution time to run next. Preemptive or non-preemptive ordering is both possible for shortest job first.

Shortest job first is thought to be the best practice due of its simplicity. It also cuts down on the typical amount of time that other operations take to execute.

The terms shortest job first (SJF), shortest job next (SJN), and shortest process next are frequently used (SPN).

There are also some drawbacks to the shorter tasks being completed first. One effect of having several shorter processes is that it may result in process starvation for longer jobs.

Another is the need to be aware of each process's approx. anticipated execution time. This is frequently so difficult in so many system or cases.

A. Normalization. Normalization is a process used to organize a database in a way that reduces redundancy and dependency.

Normalization is a common technique used to improve the performance of a database by reducing the amount of data that needs to be accessed and processed. By organizing the data in a more efficient manner, normalization can help to improve the overall performance of a database, particularly when it is accessed frequently or by multiple users.

Client-side input validation and server-side input validation are both techniques used to validate user input and ensure that it is in the correct format.

A set of instructions for working with data is called a query. To carry out these instructions, you run a query. As well as returning outcomes — which can be arranged, gathered, or sifted — a question can likewise make, duplicate, erase, or change information.

The most fundamental reason for a query's poor performance is that it processes too much data. Some queries simply require extensive data shifting and cannot be avoided. But that's unusual; Changes can be made to most bad queries to access less data. The two-step process of analyzing a poorly performing query has proven useful to us:

Check to see if your application is obtaining more data than necessary. In most cases, this indicates that it is accessing too many rows, but it could also be accessing too many columns. Determine if the MySQL server is analyzing more rows than necessary. Action queries come in four varieties: make-table queries, append queries, delete queries, update queries, and so on. Action queries modify the data in the tables they are based on, with the exception of make-table queries, which create new tables. If you make changes with an action query that you later decide you didn't want to make, you will typically need to restore the data from a backup copy because these changes cannot be easily undone, such as by pressing CTRL+Z. Before running an action query, you should always ensure that you have a fresh backup of the underlying data.

A telephone number is a set of digits that is assigned to a landline telephone subscriber station that is connected to a phone line, to a wireless electronic telephony device, such as a radio telephone or a mobile telephone, or to other devices in order to transmit data over the public switched telephone network (PSTN) or other public and private networks.

When switching calls, a telephone number serves as an address using a system of destination code routing. On the calling party's originating phone set, the calling party enters or dials a telephone number, and the originating phone set sends the entered or dialled numbers as a signal to a phone exchange. The exchange concludes the call by connecting it to the called party over the PSTN or to a different subscriber who is locally connected.
