Data Integrity.

In the e-Business environment, it is vital that the users, whether B2B, B2C or any other EC, must be able to rely upon the integrity of the data in the system.

This is particularly important for customers, because they don’t have access to information contacts within an organisation.

Standard methods such as Validation and Verification are important however, in the e-Business environment it is necessary to utilise far more sophisticated methods in addition.


What is Data Integrity?

Simply put, it is the validity of data.


How can it be compromised?

• Human error: on entry of data and when the data is transmitted.
• Software: bugs or viruses.
• Hardware: e.g. disk crashes.
• Natural disasters: fires, floods etc.

How can you reduce the likelihood of these threats?

• Back up regularly
• Control access to data via security measures
• Design user interfaces that prevent the input of invalid data.
• Use error detection and correction software when transmitting data.

Some of these features will now be described in more detail.


Software bug: An error or defect that causes software to malfunction – often caused by conflicts in software when applications try to run in tandem.

User interface: (UI) the junction between a user and a computer program. An interface is a set of commands or menus through which a user communicates with a program. A command-driven interface is one in which you enter commands. A menu-driven interface is one in which you select command choices from various menus displayed on the screen.

Graphical user interfaces (GUIs) use windows, icons and pop-up menus.


Error detection: In communications, error detection refers to a class of techniques for detecting garbled messages. Two of the simplest techniques are checksum and CRC.

checksum: A simple error-detection scheme in which each transmitted message is accompanied by a numerical value based on the number of set bits in the message. The receiving station then applies the same formula to the message and checks to make sure the accompanying numerical value is the same. If not, the receiver can assume that the message has been garbled.

CRC: Short for cyclic redundancy check, a common technique for detecting data transmission errors. Transmitted messages are divided into predetermined lengths that are divided by a fixed divisor. According to the calculation, the remainder number is appended onto and sent with the message. When the message is received, the computer re-calculates the remainder and compares it to the transmitted remainder. If the numbers do not match, an error is detected. A number of FTP’s, including Zmodem, use CRC in addition to checksum.


More sophisticated techniques include:

MNP – Microcom Networking Protocol: a communications protocol developed by Microcom Inc. Used by high speed modems, it (MNP) supports several different classes of communication, each higher class provides additional features. Modems can support one or more classes. Class 4 provides error detection and automatically varies the transmission speed based on the quality of the line. Class 5 provides data compression, Class 6 attempts to detect the highest transmission speed of the modem at the other end of the connect and transmit at that speed.

The most common levels of MNP support are Class 4 and Class 5, often called MNP-4 and MNP-5. Using the data compression techniques provided by MNP-5, devices can double normal transmission speeds. Because MNP is usually built into the modem hardware, it affects all data transmission. In contrast, software protocols, such as Xmodem and Kermit, affect only file transfer operations.


CCITT – Comite Consultatif International Telephonique et Telegraphique: an organization that sets international communications standards, CCITT (now known as ITU) has defined many important standards for data communications, including the following:

Group 3; Group 4; V.21; V.22; V.22bis; V.29; V.32; V.32bis; V.34; V.42; V.42bis; V.90; X.25; X.400 and X.500 – descriptions follow ..











Group 3: The universal protocol for sending Fax documents across telephone lines.

Group 4: A protocol for sending FAX documents over ISDN networks – supports images up to 400 dpi resolution.

V.21: The standard for full-duplex communication at 300 baud in Japan and Europe.

V.22: The standard for half-duplex communication at 1200 bps in Japan and Europe.

V.22bis: The world standard for full-duplex modems sending and receiving data across telephone lines at 1200 or 2400 bps.

V.29: half-duplex modem standard for sending and receiving data across telephone lines at 1200, 2400, 48000 or 9600 bps – this is the protocol used by fax modems.

V.32: full-duplex standard for sending and receiving data across telephone lines at 4800 or 9600 bps. V32 modems automatically adjust their transmission speeds based on the quality of the lines.

V.32bis: V.32 extended to speeds of 7200, 12000 and 14400 bps.

V.34: full-duplex standard for sending and receiving data across telephone lines at up to 28000 bps – automatically adjust the transmission speed based on the line quality.

V.42: An error-detection standard for high-speed modems. V42 can be used with digital telephone networks.

V.42bis: A data compression protocol that can enable modems to achieve a data transfer rate of 34000 bps.

V.90: full-duplex standard for sending and receiving data across telephone lines at up to 56600 bps.

X.25: The most popular packet-switching protocol for WANs.

X.400: The universal protocol for e-mail.

X.500: An extension to X.400 that defines addressing formats so that all e-mail systems can be linked together.

hi i posted my super rare values in the correct bit
and pressed post thread and then only the 1st 2s entences of the thread was there so i did it again and the same thing happened
plz dnt give me an infraction for spamming cause i havent done anythng wrong could u plz go to this threads and post saying what happened thank you
im still not sure what happened and i am going to contact habbox ty
