Data integration involves combining data residing in different sources and providing users with a unified view of these data. This process becomes significant in a variety of situations, which include both commercial (when two similar companies need to merge their databases) and scientific (combining research results from different bioinformatics repositories, for example) domains.

The assurance that information can only be accessed or modified by those authorized to do so. Measures include controlling the physical environment of networked terminals and servers, access control, and maintaining rigorous authentication practices.

A key (a variable value that is applied to a string or block of text to encrypt or decrypt it) that is used to encrypt or decrypt data only and is not used to encrypt or decrypt other keys, as some encryption formulas call for.

A Data lake is a large storage repository that "holds data until it is needed", in its native format. The term was coined by James Dixon, Pentaho chief technology officer.

The time it takes for data packets to be stored or retrieved. In Business Intelligence (BI), data latency is how long it takes for a business user to retrieve source data from a data warehouse or business intelligence dashboard.  

A policy-based approach to managing the flow of an information system's data throughout its life cycle: from creation and initial storage to the time when it becomes obsolete and is deleted. well as applications.

The service provided by the Data Link layer of function defined in the Open Systems Interconnection (OSI) model for network communication. 

The protocol layer in a program that handles the moving of data in and out across a physical link in a network. The Data-Link Layer is layer 2 in the Open Systems Interconnect (OSI) model for a set of telecommunication protocols.

Data List is a list of data in any format.

The Data Loader is an easy to use graphical tool that helps you to get your data into Salesforce objects. By integrating Force.com API, you can also use Data Loader to extract data from database objects, perform bulk deletions by exporting the ID fields for the data you wish to delete.

A data log is a piece of information (raw data) stored about a particular transaction along with the time of its occurance for future purpose.

Data loss prevention (DLP) is a strategy for making sure that end users do not send sensitive or critical information outside the corporate network. The term is also used to describe software products that help a network administrator control what data end users can transfer.

A set of information security tools used  to stop users from sending sensitive information outside of the corporate network. DLP products use business rules to examine file content and tag confidential information so that users cannot disclose it.

Data management is the development and execution of architectures, policies, practices and procedures in order to manage the information lifecycle needs of an enterprise in an effective manner.

The exponential growth of data across organizations has increased the demand for better Data Management techniques and the rise of Data Managers. Data Managers don't simply oversee the storage of information in a system. As technology changes and new advances are made, data managers must keep up with the current developments in database design, architecture, storage & retrieval and safeguard data from hackers and security breaches.

Data mapping is a process used in data warehousing by which different data models are linked to each other using a defined set of methods to characterize the data in a specific definition. This definition can be any atomic unit, such as a unit of metadata or any other semantic. This data linking follows a set of standards, which depends on the domain value of the data model used.
