Built on top of AppleTalk Session Protocol ( for legacy AFP over DDP ) or the Data Stream Interface ( for AFP over TCP ), it provides services for authenticating users ( extensible to different authentication methods including two-way random-number exchange ) and for performing operations specific to the Macintosh HFS filesystem.

Data compression methods allow in many cases to represent a string of bits by a shorter bit string (" compress ") and reconstruct the original string (" decompress ") when needed.

Data analysis encompasses methods for processing both quantitive ( numerical ) and qualitative ( non-numerical ) research data.

Such modification can be applied to the PDU ( Protocol Data Unit ), to the time relations between the exchanged PDUs, or both ( hybrid methods ).

Most such methods do rely on comparisons between the sequence to be predicted and sequences of known structure in the Protein Data Bank and thus account for environment indirectly, assuming the target and template sequences share similar cellular contexts.

* Data Facility Product ( DFP ) ( Provides access methods to enable I / O to DASD subsystems and Tape )

Data mining is the process of applying these methods with the intention of uncovering hidden patterns in large data sets.

Data mining methods have also been applied to dissolved gas analysis ( DGA ) in power transformers.

Core Data also does not provide the equivalent of an EOModelGroup — the NSManagedObjectModel class provides methods for merging models from existing models, and for retrieving merged models from bundles.

Data collection methods are meant to capture the " social meanings and ordinary activities " of people ( informants ) in " naturally occurring settings " that are commonly referred to as " the field.

Data are not simply returned in the form of a written report but instead are fed back in open joint sessions, and the client and the change agent collaborate in identifying and ranking specific problems, in devising methods for finding their real causes, and in developing plans for coping with them realistically and practically.

Guidelines for correct application of statistical methods to POD tests can be found in ASTM E2862 Standard Practice for Probability of Detection Analysis for Hit / Miss Data and MIL-HDBK-1823A Nondestructive Evaluation System Reliability Assessment, from the U. S. Department of Defense Handbook.

Electronic Data Processing ( EDP ) can refer to the use of automated methods to process commercial data.

The group has developed methods to represent human relationships using XHTML called XHTML Friends Network ( XFN ) and XHTML Meta Data Profiles ( XMDP ), for use in weblogs.

Since analytics can require extensive computation ( See Big Data ), the algorithms and software used for analytics harness the most current methods in computer science, statistics, and mathematics.

Productive inefficiency, Resource-market inefficiency and X-inefficiency might be analyzed using Data Envelopment Analysis and similar methods.

Data constraints can be addressed by reconstructing baseline data from secondary data or through the use of multiple methods.

Data within an enterprise can be stored in various formats, including relational databases ( which themselves come in a large number of varieties ), text files, XML files, spreadsheets and a variety of proprietary storage methods, each with their own indexing and data access methods.

Data on such comparisons together with data on the effect of light intensity are given in Table 1.

Data links such as Link 11, 16, 22 and BOWMAN, JTRS and even TETRA provide the means of transmitting data ( such as images, targeting information etc.

Data communications can be especially important for artillery because by using structured messages and defined data types fire control messages can be automatically routed and processed by computers.

The RODS laboratory's first efforts eventually led to the establishment of the National Retail Data Monitor, a system which collects data from 20, 000 retail locations nation-wide.

The 1. x releases focused on managing key / value data storage and are referred to as " Data Store " ( DS ).

Also in case of Single Instructions Multiple Data — a case when a lot of data from the same type has to be processed, modern processors can disable parts of the pipeline so that when a single instruction is executed many times, the CPU skips the fetch and decode phases and thus greatly increases performance on certain occasions, especially in highly monotonous program engines such as video creation software and photo processing.

Data collected include population data ( citizenship, place of residence, place of birth, position in household, number of children, religion, languages, education, profession, place of work, etc.

Cellular Digital Packet Data ( CDPD ) was a wide-area mobile data service which used unused bandwidth normally used by AMPS mobile phones between 800 and 900 MHz to transfer data.

* Data conditioning, the use of data management techniques in a computer system

The Data Encryption Standard ( DES, or ) is a previously predominant algorithm for the encryption of electronic data.
