Database Design

The DNS database features a distributed hierarchical tree structure containing what are called resource records (RR) of various types: Start of Authority (SOA), IP addresses, SMTP mail exchanges, name servers, pointers for reverse look ups, and domain name aliases. DNS is a naming system for any device connected to either the Internet or to a private network. See the ICANN web site for more information.

The motherboard, the processor (CPU), the random access memory (RAM), the Hard Drive and a power supply. You will also need a video card, if you want to see it on a monitor and a sound card, if you want to hear it through speakers. Many motherboards have the video card and sound card built into them. Also a Mouse, Keyboard and an operating system (windows, linux, Mac OS).

Pizza Hut, along with many other companies owned by YUM Brands, uses extensive I.S. technology to create world class, real-time data about the operations of every corporate owned unit. Service times are calculated and used to find the best uses for labor and sales trends are obtained from customer information on a database that is used to make analytical strategic business decisions. Thus, Pizza Hut retains customers and obtains new customers through a robust Information System (I.S.) that delivers a competitive advantage to the company.

'hz' refers to a frequency, not a unit of storage, while the word 'bits' refers to a fraction of a unit of computer storage. Therefore, this question has no logical answer.

Further, the use of a lower case 'm' may denote a unit of one millionth of a unit (as in 'micro' terms), while an upper-case 'M' may specify one million units (as in 'mega' terms). This asks the question, then, 'What was the questioner looking for?'

Your studies should include those disciplines and technologies that facilitate your carrier path. If for example you wish to become an Oracle Database developer then you would want to take up studies that train you in and certify your development in Oracle database systems.

A table stores data. Tables have fields in them, like name, address, date of birth etc. They are often likened to columns. One individual set, like your name, address and date of birth is a record. So tables have records in them. In a relational database there is more than one table and these tables are related to each other. So one table might store all your personal details and another my store all your employment details. By having at least one common field, like an employee number, these two tables can be related to each other. Access is a database application and has the capability to create relational databases.

An action performed is something that you did.

A performed action is an action that exists.

To retrieve or modify data in the database query are used. There are four types of commands in SQL. Select command is data retrieval language command and is used to retrieve data from a database.

In database there Four types of languages which contains various commands. Select command is the only command that is used for retrieval of data.

It is used as a connection between the hardware and the liveware.

Secure group communication in mobile ad hoc networks is often dynamic and impromptu, and thus re-

quires efficient and automated secure group management and seamless combination of secure groups with

distributed applications running upon them. CRTDH sceme by Balachandran et. al. [75] has been proposed

in 2005. This scheme has been used in later access control frameworks like in [76]. The scheme considers the

Chinese Remainder Theorem and Diffie-Hellman Key exchange to achieve distributed key-management for

SGC in wireless ad hoc networks. Assuming a group of n users, U1;U2; :::Un has to be formed, the following

operations are performed by each member Ui (where i = 1; 2; :::n) to obtain the shared group key.

Ui selects the Diffie-Hellman private share xi and broadcasts the public share yi = gximodp. Ui then

receives the public shares from all other members in the group and computes the DH key shared with each

of them. as mij = yxi

i mod p, where j = 1; :::; i 1; i + 1; :::n and j = i. Least Common Multiple (LCM)

of all the DH keys calculated is noted as lcmi. Ui then randomly selects ki, such that ki < min(mij ; 8j),

which will be its share of the group key. Ui also selects an arbitrary number D such that D = ki and another

number Dp such that the gcd(Dp; lcmi) = 1. Each member then solves the CRT

crti = ki mod lcmi

crti = D mod Dp

and broadcasts it to the group. After Ui receives the crt values from all the other members in the group and

calculate kj = crtj mod mij , for all j = i and compute the group key GK = k1 k2 :::kn As can be seen

from the above steps, the Chinese Remainder Theorem is used to send each member's key share (disguised)

to all the other members in the group. The Difie-Hellman key exchange is performed to derive the modulo

value in the CRT calculation. To understand the details of the scheme, let us consider a member U1 in a

group of 4 members. The first two steps of the protocol involve the generation and distribution of the DH

public share by each member in the group. U1 selects a DH private share x1 and computes its DH public share y1 = gx1 mod p. U1 then broadcasts the DH public share y1 to all the other members in the group. In

Step 3 of the protocol, all the mij values are generated, which are nothing but the DH keys shared between

U1 and the other members. U1 calculates three m values m12;m13;m14 which are equal to yx12; yx13; yx14

respectively. y2; y3; y4 are the DH public shares of members U2;U3;U4 broadcasted in Step 2. The three DH

keys (m12;m13;m14) generated by U1 are equal to m21;m31;m41 generated by U2;U3;U4 respectively. U1

then calculates the LCM of the DH keys m12;m13andm14. This LCM value will be later used for the CRT

calculation in Step 6. Step 5 of the protocol involves the generation of a random key share k1 by U1. This

k1 share has to be less than all DH keys m1;m2andm3 and the lcm1 value since we want the other members

to obtain k1 and not k1(modmij) or k1(modlcm1) respectively. In the next step, U1 generates an arbitrary

number D and Dp which will be used in solving the CRT. The Dp value should be selected such that Dp

and lcmi are co-primes, in order to solve the CRT. Also, the number D should not be equal to k1, since if

they are, then the solution to the CRT will be equal to the group key, k1. After solving the CRT in Step 6,

the solution is broadcasted to the group in Step 7. U1 solves the CRT to obtain crt1 and broadcasts it to

the the group. U1 also receives the CRT values crt2; crt3; crt4 from the other members in the group. U1 can

obtain k2; k3; k4 by performing the following operations.

k2 = crt2( mod m12)

k3 = crt3( mod m13)

k4 = crt4( mod m14).

The individual ki shares are then XOR-ed to obtain the group key GK. Similarly all the members in the group arrive at the same group key, since the following holds kj = crtj mod LCMj = crtj mod mij. Any member,

such as Ui, receives the (broadcast) values crt1 from U1; :::; crti 1 from Ui 1; crti + 1from Ui + 1; :::;and

crtn from Un. Ui can then compute k1; :::; ki 1; ki+1; :::and kn using m(i; 1); :::;m(i; i 1);m(i; i+1); ::: and

m(i; n) respectively. Along with its own ki;Ui has all the elements for computing the group key. As a result,

all the members will compute the same key.

Database is used for storing data that are related. We need database in every field for storing data.

Although an area code is a numeric value, it is not in fact a measurement in the usual sense of "quantitative data." It is more analogous to a name (a nominal scale, per S. S. Stevens) than a quantity; thus, I would classify the area code as qualitative, rather than quantitative, data.

The components of an e-marketplace are: Customers, Sellers, Products and services, Infrastructure, Front end, Back end, Intermediaries, Other business partners, and Support services.

An ER diagram is an "Entity Relationship" diagram, which illustrates the relationships between the entities in a data model.

A data model for a timetable management system might have entities like Days, Periods and Rooms. Its ER Diagram would then show that a Day is broken down into multiple Periods, and each Room might be used for multiple Periods.

Short answer: legal risk and public goodwill.

Assume first that the question is about 'corporate' information. There is a tension between transparancy, accountability, and individual privacy. To balance these tensions, some U.S. industries publish guidelines, e.g., education has FERPA guidelines and medical has HIPPA guidelines. The financial sector has guidelines also. Similar guidelines are published by other countries. Step outside those guidelines and you risk legal action. Even if your industry is not one of the above, information confidentiality standards are becoming generaly accepted in the public mind. It is good business even good marketing to meet those expectations and say so. All this is about corporate information collected on individuals.

What about corporate information about the corporation. This is a different topic and there are long established standards on what inforation should be disclosed and what information is proprietary. Check with your audtiting or legal resources.

Hi,

High level Data modelling is the process of define and analyze the data requirement.

People create databases. If you have a list of names of your friends on paper or in your phone, that is a database that you have created. Businesses create them to store information on things like their staff or products they sell or their customers. Doctors and hospitals have ones for patients. Schools, colleges and universities have ones for their students. All sorts of people and organisations have them. Some software companies create software to create databases like Oracle or Microsoft Access etc.
