It is true. RDBMS enforce integrity rules automatically. Integrity rules are automatically enforced by RDBMSs.

Integrity rules are automatically enforced by RDBMSs. Because it contains the design choices made regarding tables and their structures, a data dictionary is frequently referred to as "the database designer's database." Any character or symbol intended for mathematical manipulation may be contained in character data.

Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of RDBMS. Each table row in a relational database is a record with a distinct ID known as the key.

It is simple to determine the associations between data points because the table's columns carry the properties of the data and each record typically has a value for each property.

The older computer had a CPU that ran at 266MHz compared to a current CPU that runs 3.7GHz. How many times faster is the new CPU
sergij07 [2.7K]

Answer:

Number of times new computer faster than old computer = 13.90 times (Approx)

Explanation:

Given:

Clock speed of old computer = 266 MHz

Clock speed of new computer = 3.7 GHz

266MHz = 0.266GHz

Find:

Number of times new computer faster than old computer

Computation:

Number of times new computer faster than old computer = Clock speed of new computer / Clock speed of old computer

Number of times new computer faster than old computer = 3.7 / 266

Number of times new computer faster than old computer = 3.7 / 0.266

Number of times new computer faster than old computer = 13.90 times (Approx)

Programmers use a(n) ____ when they need the computer to repeatedly process one or more program instructions until some conditio
Arlecino [84]

Answer:

Loop

Explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Programmers use a(n) <u>loop</u> when they need the computer to repeatedly process one or more program instructions until some condition is met, at which time the <u>loop</u> ends.

<u><em>Loops</em></u> repeat a certain set of instructions until a certain condition is acuired and then exit out of the loop. There are a couple of different types of loops such as For Loop, While Loop, and Do-While loop. Each repeats a set of instructions but for a different set of times.

<u><em>For Loops</em></u> repeat for a fixed amount of Times or until the condition is met and it breaks out of the loop. Meanwhile,  <em><u>While</u></em> and <em><u>Do-While</u></em> loops keep repeating until the condition is me, but the Do-While checks the condition at the end of the loop.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

As it is a good practice that C# broughtback the concept of GOTO statement and Pointer? If your answer isyes then how C# control
zhenek [66]

Answer:

No for GOTO

Yes for Pointer

Explanation:

<u>GOTO statement</u>

This declaration is used to pass control to the program's marked declaration. The label is the valid identifier and is positioned just before the declaration from which the control is transmitted.

It becomes hard to trace a program's control flow, making it hard to comprehend the program logic. Any program in C language can be written without using a GOTO statement.

<u>Pointers</u>

A C # pointer is nothing but a variable holding another type of memory address. However, in C # pointer only the memory address of the value types and arrays can be declared.

C # supports pointers to a restricted extent. Unlike reference kinds, the default trash collection system does not track pointer kinds. Pointers are not allowed to point  to a type of structure containing a type of reference or a type of reference.

During the garbage collection process, the C #garbage collector can move objects in memory as they wish. The C #offers a unique fixed keyword for telling Garbage Collector not to move an item. This implies that the place of the value kinds referred to is fixed in memory. This is called pinning in C #.
