2. Change data capture - Wikipedia

   en.wikipedia.org/wiki/Change_data_capture

   In databases, change data capture (CDC) is a set of software design patterns used to determine and track the data that has changed (the "deltas") so that action can be taken using the changed data. The result is a delta-driven dataset .

3. Extract, transform, load - Wikipedia

   en.wikipedia.org/wiki/Extract,_transform,_load

   Some ETL systems have to scale to process terabytes of data to update data warehouses with tens of terabytes of data. Increasing volumes of data may require designs that can scale from daily batch to multiple-day micro batch to integration with message queues or real-time change-data-capture for continuous transformation and update.

4. Automatic identification and data capture - Wikipedia

   en.wikipedia.org/wiki/Automatic_identification...

   Capturing data can be done in various ways; the best method depends on application. In biometric security systems, capture is the acquisition of or the process of acquiring and identifying characteristics such as finger image, palm image, facial image, iris print, or voiceprint which involves audio data, and the rest all involve video data.

5. Staging (data) - Wikipedia

   en.wikipedia.org/wiki/Staging_(data)

   The staging area supports efficient change detection operations against target systems. This functionality is particularly useful when the source systems do not support reliable forms of change detection, such as system-enforced timestamping, change tracking or change data capture (CDC).

6. Slowly changing dimension - Wikipedia

   en.wikipedia.org/wiki/Slowly_changing_dimension

   In data management and data warehousing, a slowly changing dimension (SCD) is a dimension that stores data which, while generally stable, may change over time, often in an unpredictable manner. [1] This contrasts with a rapidly changing dimension , such as transactional parameters like customer ID, product ID, quantity, and price, which undergo ...

7. Data scraping - Wikipedia

   en.wikipedia.org/wiki/Data_scraping

   A screen fragment and a screen-scraping interface (blue box with red arrow) to customize data capture process. Although the use of physical "dumb terminal" IBM 3270s is slowly diminishing, as more and more mainframe applications acquire Web interfaces, some Web applications merely continue to use the technique of screen scraping to capture old screens and transfer the data to modern front-ends.

8. Data logger - Wikipedia

   en.wikipedia.org/wiki/Data_logger

   A data logger (also datalogger or data recorder) is an electronic device that records data over time or about location either with a built-in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer), and called digital data loggers (DDL).

9. Data integration - Wikipedia

   en.wikipedia.org/wiki/Data_integration

   Data integration refers to the process of combining, sharing, or synchronizing data from multiple sources to provide users with a unified view. [1] There are a wide range of possible applications for data integration, from commercial (such as when a business merges multiple databases) to scientific (combining research data from different bioinformatics repositories).
