Answer:

definition

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.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

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.

Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.

Hence, the data definition component of a database management system (DBMS) is used to create and maintain the data dictionary.

Kitty [74]

Answer:

The correct answer is letter "A": commit with fallback.

Explanation:

American Professor Alfred A. Marcus (born 1950) in his book "<em>The Future of Technology Management and the Business</em>" (2015) describes that hedging may be a strategy to shield businesses from the rapidly evolving world they face as a result of the continuous implementation of technology in the market. According to Marcus, there are 5 hedge approaches that firms should implement:

  1. Gamble on the most probable:<em> work on the product with the highest success rate. </em>
  2. Take the robust route: <em>invest in as many products as possible. </em>
  3. Delay until further clarity emerges:<em> waiting for a proper moment to react in front of market changes. </em>
  4. <u>Commit with a fallback</u>:<em> adapt according to the market. </em>
  5. Try to shape the future:<em> innovate.</em>

HELP ME ILL GIVE BRAINLY Input 50 numbers and then output the average of the negative numbers only. Write in pseudocode!
Mumz [18]

Answer:

The explanation is for 10 inputs though. You'd have to follow these steps to find input 50 numbers.

Explanation:

This is how I wrote it in the Plain English programming language which looks like pseudo-code but compiles and runs (to save you all the rest of the steps):

To run:

Start up.

Write "Enter 10 numbers separated by spaces: " on the console.

Read a reply from the console.

Loop.

If the reply is blank, break.

Get a number from the reply.

Add 1 to a count.

Add the number to a total.

Repeat.

Write "The total is: " then the total on the console.

Put the total divided by the count into an average.

Write "The average is: " then the average on the console.

Refresh the screen.

Wait for the escape key.

Shut down.

xxMikexx [17]

Answer:

Here is the GamePoints constructor:

GamePoints::GamePoints() :

/* Your code goes here */

{

teamLions = 500;

teamDolphins = 500;

}    

Explanation:

Here is the complete program:

#include  //to use input output functions

using namespace std; //to identify objects like cin cout

class GamePoints {  //class GamePoints

   public: GamePoints(); // constructor of GamePoints class

   void Start() const;  //method of GamePoints class

   private: //declare data members of GamePoints class

   int teamDolphins; // integer type private member variable of GamePoints

   int teamLions; }; // integer type private member variable of GamePoints

   GamePoints::GamePoints()  //constructor

    { teamLions = (500), teamDolphins= (500); }   //assigns 500 to the data members of teamLions  and teamDolphins of GamePoints class

   void GamePoints::Start() const    { //method Start of classs GamePoints

       cout << "Game started: Dolphins " << teamDolphins << " - " << teamLions << " Lions" << endl; }  //displays the values of teamDolphins and teamLions i.e. 500 assigned by the constructor

       int main() //start of main() function

       { GamePoints myGame;  // creates an object of GamePoints class

       myGame.Start(); //calls Start method of GamePoints class using the object

       return 0; }

The output of the program is:

Game started: Dolphins 500 - 500 Lions
