Answer:

False.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

In database management, the term "schema" is used to denote a representation of data.

A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.

A relational database can be defined as a type of database that is structured in a manner that there exists a relationship between its elements.

In the physical table of a relational database, a record used in the logical design of a database corresponds to a row.

You will write code to manipulate strings using pointers but without using the string handling functions in string.h. Do not include string.h in your code. You will not get any points unless you use pointers throughout both parts.
You will read in two strings from a file cp4in_1.txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i] = a[i], but rather *c *a is allowed. You will not get any points unless you use pointers.
Example:
Input file output file
ABCDE APBQCRDSETFG
PQRSTFG arrow abcdefghijklmnopgrstuvwxyz
acegikmoqsuwyz

The new software organization requires a new point of sale and stock control system for their many stores throughout Pakistan to replace their aging mini-based systems.
A sales assistant will be able to process an order by entering product numbers and required quantities into the system. The system will display a description, price, and available stock. In-stock products will normally be collected immediately by the customer from the store but may be selected for delivery to the customer's home address for which there will be a charge. If stock is not available, the sales assistant will be able to create a backorder for the product from a regional warehouse. The products will then either be delivered directly from the regional warehouse to the customer's home address, or the store for collection by the customer. The system will allow products to be paid for by cash or credit card. Credit card transactions will be validated via an online card transaction system. The system will produce a receipt. Order details for in-stock products will be printed in the warehouse including the bin reference, quantity, product number, and description. These will be collected by the sales assistant and given to the customer. The sales assistant will be able to make refunds, provided a valid receipt is produced. The sales assistant will also be able to check stock and pricing without creating an order and progress orders that have been created for delivery.

You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.

One of your suppliers has recently been in the news. Workers complain of long hours, hot and stuffy workrooms, poor lighting, and even no functioning bathrooms. Some workers are less than 14 years old. Workers are paid 10 cents for each piece they complete, and fast workers are capable of finishing 50 pieces.

The divBySum method is intended to return the sum ofall the elements in the int arrayparameter arr that are divisible by the intparameter num. Consider the following examples, in whichthe array arrcontains {4, 1, 3, 6, 2, 9}.The call divBySum(arr, 3) will return 18,which is the sum of 3, 6, and 9,since those are the only integers in arr that aredivisible by 3.The call divBySum(arr, 5) will return 0,since none of the integers in arr are divisibleby 5.Complete the divBySum method using anenhanced for loop. Assume that arr isproperly declared and initialized. The method must use anenhanced for loop to earn full credit./** Returns the sum of all integers inarr that are divisible by num* Precondition: num > 0*/public static int divBySum(int[] arr, int num)

Write a function that takes number between 1 and 7 as a parameter and prints out the corresponding number as a string. For example, if the parameter is 1, your function should print out one. If the parameter is 2, your function should print out two, etc. If the parameter is not between 1 and 7, the function should print an appropriate error message. In your file, you should include a main() that allows the user to enter a number and calls your function to demonstrate that it works.
