Data typically reside in the storage in structures that look completely different from the way the data look in the conceptual and external levels, but in ways that attempt to optimize ( the best possible ) these levels ' reconstruction when needed by users and programs, as well as for computing additional types of needed information from the data ( e. g., when querying the database ).

Data structures ( fields, records, files and objects ) optimized to deal with very large amounts of data stored on a permanent data storage device ( which implies relatively slow access compared to volatile main memory ).

Data typically reside in the storage in structures that look completely different from the way the data look in the conceptual and external levels, but in ways that attempt to optimize ( the best possible ) these levels ' reconstruction when needed by users and programs, as well as for computing additional types of needed information from the data ( e. g., when querying the database ).

Data structures not containing code, like those above, are called plain old data structure.

Data structures are generally based on the ability of a computer to fetch and store data at any place in its memory, specified by an address — a bit string that can be itself stored in memory and manipulated by the program.

* Data structures course with animations

* 3D microtubule structures in the EM Data Bank ( EMDB )

Solved structures are usually deposited in the Protein Data Bank ( PDB ), a freely available resource from which structural data about thousands of proteins can be obtained in the form of Cartesian coordinates for each atom in the protein.

, the Protein Data Bank has over 55, 000 atomic-resolution structures of proteins.

The images below are of Lipscomb's structures from the Protein Data Bank displayed in simplified form with atomic detail suppressed.

Once the model of a molecule's structure has been finalized, it is often deposited in a crystallographic database such as the Cambridge Structural Database ( for small molecules ), the Inorganic Crystal Structure Database ( ICSD ) ( for inorganic compounds ) or the Protein Data Bank ( for protein structures ).

Data derived from the work of Oceanographers is used in marine engineering, in the design and building of oil platforms, ships, harbours, and other structures that allow us to use the ocean safely.

There are over 100 3D structures of tyrosine kinases available at the Protein Data Bank.

Data structures of FooProtocol defined using the ASN. 1 notation:

* PDBsum has links to three-dimensional structures of various alcohol dehydrogenases contained in the Protein Data Bank

Data structures are implemented in a programming language as data types and the references ( e. g. relationships, links and pointers ) and operations that are possible with them.

* 3D hemocyanin structures in the EM Data Bank ( EMDB )

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 management 4GLs such as SAS, SPSS and Stata provide sophisticated coding commands for data manipulation, file reshaping, case selection and data documentation in the preparation of data for statistical analysis and reporting.

In telecommunication, Advanced Data Communication Control Procedures ( or Protocol ) ( ADCCP ) is a bit-oriented data link layer protocol used to provide point-to-point and point-to-multipoint transmission of data frames that contain error control information.

* At the Data Link Layer: The IEEE 802. 2 protocol at the Logical Link Control sublayer of the data link layer may provide both connectionless and connection-oriented services.

The Flight Data Subsystem ( FDS ) and a single eight-track digital tape recorder ( DTR ) provide the data handling functions.

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.

* Electronic Technical Data used to provide data for the combat modelling applications

Furthering this, Linked Data also introduces Dereferenceable Uniform Resource Identifiers, which provide data-by-reference which is found in object-oriented programming and object-oriented databases in the form of object identifiers.
