ADO.NET is a data access technology from the Microsoft.NET Framework that provides communication between relational and non-relational systems through a common set of components. ADO.NET is a set of computer software components that programmers can use to access data and data services from a database. It is a part of the base class library that is included with the Microsoft.NET Framework. It is commonly used by programmers to access and modify data stored in relational database systems, though it can also access data in non-relational data sources. ADO.NET is sometimes considered an evolu ...

ANSI 834 Enrollment Implementation Format

The ANSI 834 EDI Enrollment Implementation Format is a standard file format in the United States for electronically exchanging health plan enrollment data between employers and health insurance carriers. The Health Insurance Portability and Accountability Act HIPAA requires that all health plans or health insurance carriers accept a standard enrollment format: ANSI 834A Version 5010. An 834 file contains a string of data elements, with each representing a fact, such as a subscriber’s name, hire date, etc. The entire string is called a data segment. The 834 is used to transfer enrollment in ...

Approximate inference

Approximate inference methods make it possible to learn realistic models from big data by trading off computation time for accuracy, when exact learning and inference are computationally intractable.

Association rule learning

Association rule learning is a rule-based machine learning method for discovering interesting relations between variables in large databases. It is intended to identify strong rules discovered in databases using some measures of interestingness. Based on the concept of strong rules, Rakesh Agrawal, Tomasz Imielinski and Arun Swami introduced association rules for discovering regularities between products in large-scale transaction data recorded by point-of-sale POS systems in supermarkets. For example, the rule { o n i o n s, p o t a t o e s } ⇒ { b u r g e r } {\displaystyle \{\mathrm {on ...

Atomicity (database systems)

In database systems, atomicity is one of the ACID transaction properties. An atomic transaction is an indivisible and irreducible series of database operations such that either all occur, or nothing occurs. A guarantee of atomicity prevents updates to the database occurring only partially, which can cause greater problems than rejecting the whole series outright. As a consequence, the transaction cannot be observed to be in progress by another database client. At one moment in time, it has not yet happened, and at the next it has already occurred in whole. An example of an atomic transacti ...

Automated tiered storage

Automated tiered storage is the automated progression or demotion of data across different tiers of storage devices and media. The movement of data takes place in an automated way with the help of a software or embedded firmware and is assigned to the related media according to performance and capacity requirements. More advanced implementations include the ability to define rules and policies that dictate if and when data can be moved between the tiers, and in many cases provides the ability to pin data to tiers permanently for specific periods of time. Implementations vary, but are class ...

Data field

A data field is a place where you can store data. Commonly used to refer to a column in a database or a field in a data entry form or web form. Fields can contain data to be entered and to display the data.


Data thinking

Data thinking is the generic mental pattern observed during the processes of picking a subject to start with, identifying its parts or components, organizing and describing them in an informative fashion that is relevant to what motivated and initiated the whole processes. This term was created by Mario Faria and rogério Panigassi in 2013, when they wrote a book about scientific data analysis, data management and how these practices were able to achieve their goals.



Data Management API is the interface defined in the X/Open document "Systems Management: Data Storage Management API" dated February 1997. XFS, IBM JFS, VxFS, AdvFS, StorNext and IBM Spectrum Scale file systems support DMAPI for Hierarchical Storage Management.


Locks with ordered sharing

In databases and transaction processing the term Locks with ordered sharing comprises several variants of the Two phase locking concurrency control protocol generated by changing the blocking semantics of locks upon conflicts. One variant is identical to Strict commitment ordering.


Online complex processing

Online complex processing is a class of realtime data processing involving complex queries, lengthy queries and/or simultaneous reads and writes to the same records.


Storage model

A storage model is a model that captures key physical aspects of data structure in a data store. On the other hand, a data model is a model that captures key logical aspects of data structure in a database. The physical storage can be a local disk, a removable media, or storage accessible via the network.
