A computer firewall limits the data that can pass through it and protects a networked server or client machine from damage by unauthorized users.
Firewalls can be either hardware or software-based. A router is a good example of a hardware device that has a built-in firewall.Software programs that monitor and restrict external access to a computer or network can also serve as firewalls. A network firewall only allows authorized traffic from the Internet to flow in and out of the network.

ODBC

Stands for "Open Database Connectivity." With all the different types of databases available, such as Microsoft Access, Filemaker, and MySQL, it is important to have a standard way of transferring data to and from each kind of database.
Any application that supports ODBC can access information from an ODBC-compatible database, regardless of what database management system the database uses.
For a database to be ODBC-compatible, it must include an ODBC database driver. This allows other applications to connect to and access information from the database with a standard set of commands. The driver translates standard ODBC commands into commands understood by the database's proprietary system.

IMAP

Business Intelligence Dashboard

A business intelligence dashboard is a data visualization tool that displays the current status of metrics and key performance indicators (KPIs) for an enterprise. Dashboards consolidate and arrange numbers, metrics and sometimes performance scorecards on a single screen. They may be tailored for a specific role and display metrics targeted for a single point of view or department. The essential features of a BI dashboard product include a customizable interface and the ability to pull real-time data from multiple sources.

Business Information Warehouse

Business Information Warehouse (sometimes shortened to "Business Warehouse" or BW) is a packaged, comprehensive business intelligence product centered around a data warehouse that is optimized for (but not limited to) the R/3 environment from SAP.

CFML

CFML (ColdFusion Markup Language) is a Web page markup language that allows a Web site developer to create pages with variable information (text or graphics) that is filled in dynamically (on the fly) in response to variables such as user input. Along with the usual Hypertext Markup Language (HTML) tags that determine page layout and appearance, the page creator uses CFML tags to bring in content based on the results of a database query or user input.

JRE software is available as both a standalone environment and a Web browser plug-in, which allows Java applets to be run within a Web browser.

KDE

Stands for "K Desktop Environment." KDE is a contemporary desktop environment for Unix systems. It is a Free Software project developed by hundreds of software programmers across the world. Both the KDE source code and the software itself are made freely available to the public.
KDE's primary benefit is the modern graphical user interface GUI it provides for Unix workstations. While Unix systems are notoriously difficult for novice users to operate, KDE makes it possible for the average user to work on a Unix system

Kernel

To understand what a kernel is, you first need to know that today's operating systems are built in "layers." Each layer has different functions such as serial port access, disk access, memory management, and the user interface itself. The base layer, or the foundation of the operating system, is called the kernel. The kernel provides the most basic "low-level" services, such as the hardware-software interaction and memory management. The more efficient the kernel is, the more efficiently the operating system will ru

Horizontal Market Software

A horizontal market is one that supplies goods to a variety of industries instead of just one. Therefore, horizontal market software is software that can be used by several different types of industries.
For example, word processing and spreadsheet programs are horizontal market applications because they can be used by many types of businesses and consumers.

EPS

Stands for "Encapsulated PostScript." EPS is a PostScript image file format that is compatible with PostScript printers and is often used for transferring files between various graphics applications. EPS files will print identically on all PostScript-compatible printers and will appear the same in all applications that can read the PostScript format.

Source Code

Every computer program is written in a programming language, such as Java, C/C++, or Perl. These programs include anywhere from a few lines to millions of lines of text, called source code.
Source code, often referred to as simply the "source" of a program, contains variable declarations, instructions, functions, loops, and other statements that tell the program how to function. Programmers may also add comments to their source code that explain sections of the code. These comments help other programmers gain at least some idea of what the source code does without requiring hours to decipher it.

Open Source

When a software program is open source, it means the program's source code is freely available to the public. Unlike commercial software, open source programs can be modified and distributed by anyone and are often developed as a community rather than by a single organization. Since the source code of an open source program can be modified by anyone, it makes sense that the software is also free to download and use.

Firmware

Firmware is a software program or set of instructions programmed on a hardware device. It provides the necessary instructions for how the device communicates with the other computer hardware. Firmware is typically stored in the flash ROM of a hardware device

Dashboard

Dashboard is a user-interface feature Apple introduced with the release of Mac OS X 10.4 Tiger. It allows access to all kinds of "widgets" that show the time, weather, stock prices, phone numbers, and other useful data.

Android

Android is a mobile operating system developed by Google. It is used by several smartphones, such as the Motorola Droid, the Samsung Galaxy, and Google's own Nexus One.
The Android operating system (OS) is based on the open Linux kernel. Unlike the iPhone OS, Android is open source, meaning developers can modify and customize the OS for each phone. Therefore, different Android-based phones may have different graphical user interfaces GUIs even though they use the same OS.

Redundancy

Redundancy is a system design in which a component is duplicated so if it fails there will be a backup.Redundancy has a negative connotation when the duplication is unnecessary or is simply the result of poor planning.

PL/SQL

In Oracle database management, PL/SQL is a procedural language extension to Structured Query Language (SQL). The purpose of PL/SQL is to combine database language and procedural programming language. The basic unit in PL/SQL is called a block, which is made up of three parts: a declarative part, an executable part, and an exception-building part.
Because PL/SQL allows you to mix SQL statements with procedural constructs, it is possible to use PL/SQL blocks and subprograms to group SQL statements before sending them to Oracle for execution. Without PL/SQL, Oracle must process SQL statements one at a time and, in a network environment, this can affect traffic flow and slow down response time. PL/SQL blocks can be compiled once and stored in executable form to improve response time.

Meta data

Metadata is data that describes other data, and is mainly used for electronically-portrayed information. Metadata helps collect the who, what, where, when, why and how of data and presents it all in a short summary. The summarized information can help display the basics about the data, which can make finding and identifying it easier.

Metadata can be used for a number of different kinds of data files, such as images, videos, text documents and web pages. The metadata descriptions of each file can provide information such as the file’s size, when it was created, what language it is in, and what programs were used to create or modify it, as well as a short description of the file’s contents

CMDB

A configuration management database (CMDB) is a database that contains all relevant information about the components of the information system used in an organization's IT services and the relationships between those components. A CMDB provides an organized view of data and a means of examining that data from any desired perspective.

SQL

SQL (Structured Query Language) is a standard interactive and programming language for getting information from and updating a database. Although SQL is both an ANSI and an ISO standard, many database products support SQL with proprietary extensions to the standard language. Queries take the form of a command language that lets you select, insert, update, find out the location of data, and so forth. There is also a programming interface

Restore Point

A restore point is a saved "snapshot" of a computer's data at a specific time. Restore points are a component of the Windows System Restore utility. By creating a restore point, you can save the state of the operating system and your own data so that if future changes cause a problem, you can restore the system and your data to the way it was before the changes were made. When a restore point is established, your computer creates a backup copy of all data at that particular time.

DKNF

Domain/key normal form (DKNF). A key uniquely identifies each row in a table. A domain is the set of permissible values for an attribute. By enforcing key and domain restrictions, the database is assured of being freed from modification anomalies. DKNF is the normalization level that most designers aim to achieve.

3NF

Third normal form (3NF)- At the second normal form, modifications are still possible because a change to one row in a table may affect data that refers to this information from another table. For example, using the customer table just cited, removing a row describing a customer purchase (because of a return perhaps) will also remove the fact that the product has a certain price. In the third normal form, these tables would be divided into two tables so that product pricing would be tracked separately.

2NF

Second normal form (2NF). At this level of normalization, each column in a table that is not a determiner of the contents of another column must itself be a function of the other columns in the table. For example, in a table with three columns containing customer ID, product sold, and price of the product when sold, the price would be a function of the customer ID (entitled to a discount) and the specific product.

1NF

First normal form (1NF). This is the "basic" level of normalization and generally corresponds to the definition of any database, namely:

* It contains two-dimensional tables with rows and columns.
* Each column corresponds to a sub-object or an attribute of the object represented by the entire table.
* Each row represents a unique instance of that sub-object or attribute and must be different in some way from any other row (that is, no duplicate rows are possible).
* All entries in any column must be of the same kind. For example, in the column labeled "Customer," only customer names or numbers are permitted.

Normalization

In creating a database, normalization is the process of organizing it into tables in such a way that the results of using the database are always unambiguous and as intended. Normalization may have the effect of duplicating data within the database and often results in the creation of additional tables.

Normalization is typically a refinement process after the initial exercise of identifying the data objects that should be in the database, identifying their relationships, and defining the tables required and the columns within each table.

KBA

Knowledge-based authentication (KBA) is an authentication scheme in which the user is asked to answer at least one "secret" question. KBA is often used as a component in multifactor authentication (MFA) and for self-service password retrieval.

Hyperion, IBM, and Oracle initiated the development of JOLAP intending it to be a counterpart to Java Database Connectivity (JDBC) specifically for OLAP.

CDO

Collaboration Data Objects (CDO) is Microsoft's technology for building messaging or collaboration applications or adding these capabilities to existing applications.
CDO is really an additional scripting interface to an existing Microsoft messaging model, the Messaging Application Programming Interface (MAPI). Collaborative Data Objects are made available through two CDO libraries. These libraries let you address programmable messaging objects (including folders, messages, recipient addresses, attachments, and other messaging components). These objects are extensions to the programmable objects, such as forms and controls, that are offered as part of Microsoft's Visual Basic program development environment.

Customer Segmentation

Customer segmentation is the practice of dividing a customer base into groups of individuals that are similar in specific ways relevant to marketing, such as age, gender, interests, spending habits, and so on. Using segmentation allows companies to target groups effectively, and allocate marketing resources to best effect.
Customer segmentation procedures include: deciding what data will be collected and how it will be gathered; collecting data and integrating data from various sources; developing methods of data analysis for segmentation; establishing effective communication among relevant business units (such as marketing and customer service) about the segmentation; and implementing applications to effectively deal with the data and respond to the information it provides.

The term originally referred to the large cabinets that housed the central processing unit and main memory of early computers

Ad Hoc Network

Ad Hoc" is actually a Latin phrase that means "for this purpose." It is often used to describe solutions that are developed on-the-fly for a specific purpose. In computer networking, an ad hoc network refers to a network connection established for a single session and does not require a router or a wireless base station.
Basically, an ad hoc network is a temporary network connection created for a specific purpose (such as transferring data from one computer to another). If the network is set up for a longer period of time, it is just a plain old local area network (LAN).

Analytic Database

An analytic database is a read-only system that stores historical data on business metrics such as sales performance and inventory levels. The information is updated on a regular basis to incorporate recent transaction data from an organization’s operational systems. An analytic database is specifically designed to support business intelligence (BI) and analytic applications, typically as part of a data warehouse or data mart.

Front-end and back-end are terms used to characterize program interfaces and services relative to the initial user of these interfaces and services.
A "front-end" application is one that application users interact with directly.
A "back-end" application or program serves indirectly in support of the front-end services, usually by being closer to the required resource or having the capability to communicate with the required resource.

Snowflake Schema

A normalized version of the STAR schema in which dimension tables are partially or fully normalized. Not generally recommended because it compromises query performance and simplicity for understanding.

Surrogate Key

It is an artificial key field, usually with system-assigned sequential numbers, used in the dimensional model to link a dimension table to the fact table. In the dimensional table, the surrogate key is the primary key which becomes a foreign key in the fact table.

STAR Schema

Referential Integrity

Referential Integrity refers to two relational tables that are directly related. Referential Integrity between related tables is established if non-null values in the foreign key field of the child table are primary key values in the parent table.

MOLAP

Multidimensional Online Analytical Processing is an analytical processing technique in which multidimensional data cubes are created and stored in separate proprietary databases.

ROLAP

Relational Online Analytical Processing(ROLAP) is an alternative to the MOLAP (Multidimensional OLAP) technology. While both ROLAP and MOLAP analytic tools are designed to allow analysis of data through the use of a multidimensional data model, ROLAP differs significantly in that it does not require the pre-computation and storage of information. Instead, ROLAP tools access the data in a relational database and generate SQL queries to calculate information at the appropriate level when an end user requests it.

HOLAP

Hybrid Online Analytical Processing is an approach to analytical processing that combines the MOLAP and ROLAP techniques. HOLAP allows storing part of the data in a MOLAP store and another part of the data in a ROLAP store. The degree of control that the cube designer has over this partitioning varies from product to product

Data Mart

A data mart is a subset of an organizational data store, usually oriented to a specific purpose or major data subject that may be distributed to support business needs. Data marts are analytical data stores designed to focus on specific business functions for a specific community within an organization. Data marts are often derived from subsets of data in a data warehouse, though in the bottom-up data warehouse design methodology the data warehouse is created from the union of organizational data marts.

CORBA

Common Object Request Broker Architecture(CORBA) is a standard defined by the Object Management Group (OMG) that enables software components written in multiple computer languages and running on multiple computers to work together. CORBA is useful because it enables separate pieces of software written in different languages and running on different computers to work together as a single application or set of services. More specifically, CORBA is a mechanism in software for normalizing the method-call semantics between application objects that reside either in the same address space (application) or remote address space (same host, or remote host on a network)

CASE

Computer Aided Software Engineering (CASE) is the scientific application of a set of tools and methods to a software system which is meant to result in high quality, defect-free and maintainable software products. It also refers to methods for the development of information systems together with automated tools that can be used in the software development process

OLAP

The Toolkit can also be used to diagnose and fix problems that may be related to compatibility.

ACD

An Automatic Call Distributor (ACD) is a telephone facility that manages incoming calls and handles them based on the number called and an associated database of handling instructions. Many companies offering sales and service support use ACDs to validate callers, make outgoing responses or calls, forward calls to the right party, allow callers to record messages, gather usage statistics, balance the use of phone lines, and provide other services.
ACDs often provide some form of Automatic Customer/Caller Identification (ACIS) such as that provided by Direct Inward Dialing (DID), Dialed Number Identification Service (DNIS), or Automatic Number Identification (ANI).

Data Aggregation

Data aggregation is any process in which information is gathered and expressed in a summary form, for purposes such as statistical analysis. A common aggregation purpose is to get more information about particular groups based on specific variables such as age, profession, or income. The information about such groups can then be used for Web site personalization to choose content and advertising likely to appeal to an individual belonging to one or more groups for which data has been collected.

B-tree

A B-tree is a method of placing and locating files (called records or keys) in a database. (The meaning of the letter B has not been explicitly defined.) The B-tree algorithm minimizes the number of times a medium must be accessed to locate a desired record, thereby speeding up the process.
B-trees are preferred when decision points, called nodes, are on hard disk rather than in random-access memory (RAM).
