Data type refers to the kind of data a variable in any programming language can hold.

For example int is used to store integer numeric values. A String is used to hold alpha numeric values.

int i = 10;

String name = "Rocky";

etc.

Each data type has its own characteristics and size.

Linked organization in data structure is the organization of data records that are linked together by references. These links are also known as connectors.

System availability is closely tied to the financial health of a company. If customers cannot get access to the company's servers then they can't order products and the company receives no revenue.

Since a company wants its servers to be as available as possible it has to consider problems relating to security. There are security attacks that prey on the availability of the company network, either by exploiting weaknesses or by using techniques such as a denial of service.

In any case, availability is not tied solely to security but it is very large part of it.

Microsoft Access

ADODB = ActiveX Data Objects for Data Base. The ADODB is collection of methods to access the data from the database for Applications developed using Microsoft Visual Studio. Example: Taken from Microsoft's MSDN-Oct-2005
CLEAR
LOCAL oConn as "adodb.connection"
LOCAL oRS as "adodb.recordset"
oConn = CREATEOBJECT('adodb.connection')
oRS = CREATEOBJECT('adodb.recordset')
cConnStrng = ;
"Provider=vfpoledb;Data Source="+HOME(2)+"Northwind\Northwind.dbc"
oConn.Open(cConnStrng)
oConn.BeginTrans()
oConn.Execute("UPDATE Customers SET contactname = 'Patricio X. Simpson';
WHERE customerid='CACTU'")
oRS = oConn.Execute("SELECT * FROM customers WHERE customerid = 'CACTU'")
?oRS.Fields("contactname").Value
oConn.RollbackTrans()
oRS.Requery()
?oRS.Fields('contactname').Value
oRS.Close()
oConn.Close()

Yes, but it cannot be done in C as intuitively as it can be done in C++:

struct X {

X (const int i): m {i} {} // converts an int to an X [C++ only]

X& operator= (const int i) { m=i; return *this; } // assign an int to an X [C++ only]

int m;

};

Usage:

X x {42}; // construct X from int

x = 0; // assign an int to an X

In C we must use a conversion function:

struct X convert (const int i) { // convert an int to an X

struct X;

x.m = i;

return x;

}

Usage:

struct X x;

x = convert (42);

XML file can be used for exchanging data . This is so because in XML file data is stored in form of nodes and sub nodes .Ex Facebook status is stored in one node then there are sub nodes for like, comment and share .

Database is collection of tables. Tables contains the data in rows & columns. The columns are defined with a Name, Data type, Length & few other parameters. The columns is nothing but the field. If you know Microsoft excel, consider a worksheet as a database table. You define a Name to each & every column and you format the cell as General, Date, Currency etc. This is also called as Field name.

Is a logical description of some portion of database that is required by user to perform some task.

"Guided Approach" is an approach proposed by Schmidt, that can be used for teaching office reading exercises. It allows an instructor to emphasize the thirteen component skills that are subsets of the two main skills, verifying and comprehending detail.

A computerised hotel reservation system gives an instant 'picture' of which rooms are booked, occupied or vacant.

A nominal variable is where you assign a number to a category. Imagine a variable called "animal" where 1=sheep, 2=cow, 3=dog, etc. Calculating the average, standard deviation or other continuous measures of "animal" in this context wouldn't make any sense. That is, an average "animal" of, say, 4.567 with standard deviation of 1.234 doesn't mean anything.

You could, however, calculate a mode, which is the most frequently occurring category.

• Sharing of Data and Resources
• Communication
• Flexibility (E.G., I have a Mac but also use departments compute power when I need it)

This operation does not violate the chest, and is combined with a bracing technique.

Who certifies the results of any poll? Generally it is the polling agency itself, through conducting spot checks on accuracy. No government agency oversees poll results, so there is nothing to make them "official," with the exception of election polls.

Election polls are are not scientific polls, as they are not random samples of public opinion. Instead, everyone eligible to vote casts a ballot. Election polls are the only "official" polls.

AS

A composite attribute consists of a group of values from more than one domain. For example, the Address attribute consists of several domains such as house number, street number, city, country, etc.

seen then.

Consider this example.

You are standing at a place p. You are to goto q. There are intermediate places C1,C2 ...

You want to minimize distance travelled.

Greedy Method of Solving

You don't want to try all intermediate places. You goto the nearest intermediate place. Why? You feel by going to the nearest intermediate place, you will minimize the distance to q.

Dynamic Programming

You try all the places, but you store the previous result. Eg: To reach C3 in minimum distance, you reached by C1. So you store C1. So if you want to go to C5, by C3, you will goto C1 then C3 and then check if going from C3 to C5 is nearest.

I would suggest you read Intro to Algorithms by CLRS to understand in greater detail.
