  Data Structure Sample Questions
A data structure is a way of storing data in a computer so that it can be used efficiently.
Different kinds of data structures are suited to different kinds of applications.
Answer: A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other.

  UDDI V2.03 Data Structure Specification
Data structures are described by substructure breakdowns in tables of the following form.
If the businessService data is rendered into XML and has no containing parent that has within its data a businessKey, the value of the businessKey that is the parent of the businessService is required to be provided.
If the bindingTemplate data is rendered into XML and has no containing parent that has within its data a serviceKey, the value of the serviceKey that is the ultimate containing parent of the bindingTemplate is required to be provided.

  Data Structure
A data structure is a scheme for organizing the data required to support one or more business systems.
It is independent of the way in which the data are physically arrayed in secondary storage.
A fundamental nature of the data structure is that every cell points to its four edges, and every edge points to its two neighboring cells.

  Data structure Summary
Data structures are implemented using the data types, references and operations on them provided by a programming language.
After the data structures are chosen, the algorithms to be used often become relatively obvious.
A data structure can be viewed as an interface between two functions or as an implementation of methods to access storage that is organized according to the associated data type.

After the data structures are chosen, the algorithm (A precise rule (or set of rules) specifying how to solve some problem) s to be used often become relatively obvious.
The fundamental building blocks of most data structures are array (An orderly arrangement) s, record (A document that can serve as legal evidence of a transaction) s, discriminated union (additional info and facts about discriminated union) s, and reference (The act of referring or consulting) s.
A data structure can be viewed as an interface between two functions or as an implementation of methods to access storage that is organized according to the associated data type (additional info and facts about data type).

 Encyclopedia: Data structure
In theoretical computer science, an abstract data structure is an abstract storage for data defined in terms of the set of operations to be performed on data and computational complexity for performing these operations, regardless the implementation in a concrete data structure.
In computing, a persistent data structure is a data structure which always preserves the previous version of itself when it is modified; such data structures are effectively immutable, as their operations do not (visibly) update the structure in-place, but instead always yield a new updated structure.
Data is arranged into records, and a special item is added to each record called a pointer (a link field), which contains a link to the next record etc. Renaming each record as a node and we have a complex data structure called a linked list.

 Macroscopic Data Structure Analysis and Optimization
This thesis presents a new class of techniques named ``Macroscopic Data Structure Analyses and Optimizations'', which is a new approach to the problem of analyzing and optimizing pointer-intensive programs.
Data Structure Analysis is a context-sensitive pointer analysis which identifies data structures on the heap and their important properties (such as type safety).
Automatic Pool Allocation uses the results of Data Structure Analysis to segregate dynamically allocated objects on the heap, giving control over the layout of the data structure in memory to the compiler.

 Modeling the enterprise data architecture
The idea is to map the major data areas in the enterprise on one axis, and the various types of models on the other axis, ranging from highly business-focused models to very detailed system structures.
Data should be recorded as accurately and completely as possible, by the most informed source, as close as possible to its point of creation, in an electronic form at the earliest opportunity, and in an auditable and traceable manner.
Data structures must be under strict change control, so that the various business and system implications of any change can be properly managed.

 Tree Data Structure
The tree data structure is defined in the files tree.def and tree.h in the GCC source code.
This structure is the link between a language front-end and the GCC back-end.
Once the Trie data structure is implemented, you will use it to write a program to generate an index for a text document.

 Triangulation Algorithms and Data Structures
The quad-edge data structure is popular because it is elegant, because it simultaneously represents a graph and its geometric dual (such as a Delaunay triangulation and the corresponding Voronoï diagram), and because Guibas and Stolfi give detailed pseudocode for implementing the divide-and-conquer and incremental Delaunay algorithms using quad-edges.
Despite the fundamental differences between the data structures, the quad-edge-based and triangle-based implementations of Triangle are both faithful to the Delaunay triangulation algorithms presented by Guibas and Stolfi [10] (I did not implement a quad-edge sweepline algorithm), and hence offer a fair comparison of the data structures.
Precisely the same data structure, ghost triangles and all, is used in the sweepline implementation to represent the growing triangulation (which often includes dangling edges).

 Data Structures
A data structure is a group of data elements grouped together under one name.
Therefore, one of the most important advantages of data structures is that we can either refer to their members individually or to the entire structure as a block with only one identifier.
Structures can also be nested so that a valid element of a structure can also be on its turn another structure.

Atomic level data sits in a data warehouse and is time variant (i.e., accurate as of some moment in time now passed).
A data model that represents the inherent structure of data without regard to either individual use or hardware or software implementation.
This type of data warehouse is difficult to build because it requires users from different divisions to come together to define a common data model for the warehouse.

OLAP is structured to allow large sums of data to be analyzed, usually in an aggregated fashion, while also allowing the user to drill-down into the details.
A data warehouse is structurally different from a data mart in that the data warehouse must serve the needs of the entire corporation.
Typically the data mart is fed data from the data warehouse, whereas the data warehouse is fed data from the operational systems, old legacy systems as well as from other pockets of data such as flat files and spreadsheets.

 Stack (data structure) Summary
As an abstract data type, the stack is a container (data structure) of nodes and has two basic operations: push and pop.
As data items are added to the stack, the stack pointer is displaced to indicate the current extent of the stack, which expands away from the origin (either up or down, depending on the specific implementation).
If data is moved to the wrong location on the stack, or an oversized data item is moved to a stack location that is not large enough to contain it, return information for procedure calls may be corrupted, causing the program to fail.

 Part 1: An Introduction to Data Structures
If you're unfamiliar with the term, data structures are abstract structures, or classes, that are used to organize data and provide various operations upon their data.
In this first part of the six-part series, we'll look at why data structures are important, and their effect on the performance of an algorithm.
Since the data structure used by an algorithm can greatly affect the algorithm's performance, it is important that there exists a rigorous method by which to compare the efficiency of various data structures.

 XML and Java technologies: Data binding, Part 1: Code generation approaches -- JAXB and more
Finally, special types of data such as numbers and dates can be converted to internal representations on input, rather than being left as text; this allows your application to work with the data values much more efficiently.
Using generated code you can be certain that your data objects are properly linked to the XML document, unlike the mapped binding approach where you need to specify the linkage directly and make sure you've properly covered all the structure variations.
For general data binding usage where XML documents are involved but aren't the main focus of the application, one of the other data binding approaches would probably be simpler.
