Terms in this set (21)
Atomicity, Consistency, Isolation, Durability. Properties of a database that help guarantee data integrity.
Adobe Flash Player
A web browser plugin which allows a variety of multimedia and interactive content to be included in web pages.
A database in which all data is stored in a single central location.
A database in which data is stored on multiple computers in separate physical locations. Various techniques are used to synchronise the data to prevent data integrity problems.
In a web environment, refers to software that runs in the user's browser rather than on the web server.
Methods used to ensure multiple (concurrent) operations can be performed on a database without causing data integrity problems. Related to ACID and record locking.
Customer relationship management (CRM) system
A computerised system for managing an organisation's customer, sales, and marketing information. This might also include customer sales and technical support.
Software added to web browsers to extend their functionality.
Technique used in databases to prevent a record being accessed by more than one user at a time. This prevents data integrity problems (such as a change by one user while another is reading it).
Mobile phone with capabilities typically including Internet access and a camera.
Portable device, often with a touch screen.
Part of ACID. A way of ensuring that database transactions either happen in their entirety, or not at all. For example, a payment from A to B must have money subtracted from person A and credited to person B. Atomicity means either both transactions occur, or neither do.
Part of ACID. Ensures that data in a database is always in a consistent state - i.e. that it follows all data validation rules. (Note that this is not the same as being correct).
Part of ACID. Ensures that one database transaction cannot unintentionally affect another. For example, two transactions to alter the same record cannot run at the same time.
Part of ACID. Durability means that once a transaction has occurred, it must "stay occurred", even if the power is lost or the hard disk crashes or there is some other disaster. This typically records a record of all transaction (a transaction log) to be kept.
Quick Response Code. A type of 2D bar code that can store more data than a regular UPC bar code.
The process of automatically customising a standard letter with individual names and addresses from a database.
Encoding system to store text, with support for multiple languages and alphabets, and thousands of characters. Compare ASCII.
Content Management System. Software which allows management of a web site without web design skills. Content is stored in a database and published in different ways, such as on a web site, in a printed booklet, or in different languages. Sometimes called a WebCMS.
Virtual Private Network
Allows a secure private connection over a public network, using an encrypted 'tunnel'. For example, a remote computer can securely connect to a LAN, as though it were physically connected.
Comma Separated Values
File format for transferring data, which stores fields and records in a plain text file, separated by commas. See also TSV (Tab Separated Values).
