	Stack (data structure) - Wikipedia, the free encyclopedia
		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.

	Tree (data structure) - Wikipedia, the free encyclopedia
		In computer science, a tree is a widely-used computer data structure that emulates a tree structure with a set of linked nodes.
		In an unordered tree, a tree is a tree in a purely structural sense - that is to say, given a node, there is no order for the children of that node.
		A tree on which an order is imposed -- for example, by assigning different natural numbers to each child of each node -- is called an ordered tree, and data structures built on them are called ordered tree data structures.

	Data Model Dictionary
		Data Store - A data store in a PAM represents a place to put information, either temporarily from process to process, or permanently as a final or finished result of a process.
		Data affiliated with a particular process should be collated in a natural manner; however, should there be tens of data pertaining to a specific process, secondary definition of sub-processes is desirable.
		Structured Query Language (SQL) - SQL is a language used to communicate with a DBMS and provides a fairly common syntax for applications to use.

		For example, each tree structure can provide the minimum and maximum path lengths from the root to a leaf, and the hash table can provide the number of buckets used, etc. These statistical operations are not provided in the generic dictionary interface because they are not applicable to each data structure.
		Every data structure is opaque to the user; only a pointer to it may be stored by the client program.
		Thus, the programmer may change the underlying data structure used, and hence the performance characteristics of the application, by simply changing a single line of code - the line which creates the dict structure.

	Spatial Data Structure (Site not responding. Last check: 2007-10-23)
		A spatial data structure is a data structure which is capable of storing and sorting objects based on multidimensional keys.
		The two-dimensional structures, such as the PR quadtree and PM1/PM3 quadtree, can store objects based on two values, such as the longitude and latitude (x, y) of a base.
		Three-dimensional structures, such as a K-d tree or a PM1 octree, can store objects based on three values, such as the longitude, latitude, and sea level (x, y, z) of a base.

		An active data dictionary is automatically updated as changes occur in the database.
		The data dictionary is a more general software utility used by designers, users, and administrators for information resource management.
		Data dictionaries are also used to document the database design process itself and can accumulate meta-data ready to feed into the system catalog.

	Dictionary of Algorithms and Data Structures
		This is a dictionary of algorithms, algorithmic techniques, data structures, archetypical problems, and related definitions.
		We do not include algorithms particular to business data processing, communications, operating systems or distributed algorithms, programming languages, AI, graphics, or numerical analysis: it is tough enough covering "general" algorithms and data structures.
		Data Structures and Algorithms is a wonderful site with illustrations, explanations, analysis, and code taking the student from arrays and lists through trees, graphs, and intractable problems.

	NOAO Image Data Structure Definitions
		The data structures are created by the data acquisition systems for use by observers, data reduction systems, and archives.
		Because multiple amplifiers read the CCD data in different orders, as described in an "amplifier" coordinate system, there will be relative flips between the different amplifiers though the pixels may be flipped when they are written to an image raster by the data acquisition system.
		The actual pixel data from an exposure are recorded in a section of the image called the "data section".

	Guile Scheme - Dictionaries in General
		A dictionary is defined to be any data structure that binds keys to values.
		Guile Scheme does not contain a universal "dictionary type" of which all actual dictionaries are instances and it does not contain a set of generic dictionary procedures that can operate on any dictionary, regardless of its actual type.
		Another aspect of the dictionary calling convention is that for each type of dictionary data structure, three dictionary types are generally provided: one each for the possibilities of comparing keys using

	CS123: Dictionary
		Pointer-based data structures, such as linked lists and trees, store information by keeping each piece of data in one object that is linked to other data by reference to objects parts of the memory.
		Pointer-based data structures are more flexible and allow the amount of information to grow or shrink over time.
		However, array based data structures are often faster, especially if you know the index, because then you can go immediately to the data without having to follow a chain of references.

	Exercise: Data Structure Scenarios
		In many data structures classes, it is common for lectures to focus on the theoretical underpinnings of the various structures and for projects to focus on implementing a specific data structure.
		Often, the current data structure topic being covered in lecture would be an answer, but not necessarily the best one.
		The data structure GrabBag is similar to a stack or a queue, but instead of the first or last element being removed on a pop or dequeue, a random element is removed on a grab.

	Dictionary Data Structure (Site not responding. Last check: 2007-10-23)
		Sometimes called "AssociativeArray", "Map", or "HashTable" (the latter is strictly an implementation of a dictionary).
		In a dictionary, you store a value with an associated key and then you may retrieve this value later using the key.
		In RDBMS (RelationalDatabase) terms, a dictionary has 2 columns, one of which is a primary (unique) key.

	Dictionary Data Structure (Site not responding. Last check: 2007-10-23)
		A dictionary data structure is one which is capable of storing objects in sorted order based on key such as a string or an integer.
		The main purpose of the dictionary is to provide us with an easy way to see what data points we have already entered into our SoftWar database.
		The term data dictionary will be used in class to refer to this component, or to a collection of components having this role.

		Returns true if the given key is in the dictionary, or false if the key is not in the dictionary.
		The test driver works by first inserting all of the words in the first file into a dictionary, the checking the dictionary to make sure it contains (1) all of the words in the second (subset) file, and (2) all of the words in the first (complete) file.
		In the report, you will run the test driver on each combination of dictionary classes and input files and then comment on the performance of the different data structures.

	Day 23 -- Working with Data Structures in Java
		In this example, a very elementary data structure such as an array might be the best solution, since all that is required of the data structure is the storage of multiple images.
		The primary difference between these data structures is that arrays and vectors are better at referencing elements via a numeric index, whereas linked lists are better at accessing data in a purely sequential manner.
		You began the lesson with a brief overview of data structures in general and why it is important to have a solid understanding of how to use them.

		All keys for these dictionary structures are strings with a fixed maximum length.
		In this mode the programmer may prefer to use the "caching" versions if they expect to retrieve the same keys many times and if the number of keys to touch is not huge (say, in the millions).

	1.1.1 Dictionaries (Site not responding. Last check: 2007-10-23)
		Dozens of different data structures have been proposed for implementing dictionaries including hash tables, skip lists, and balanced/unbalanced binary search trees -- so choosing the right one can be tricky.
		In practice, it is more important to avoid using a bad data structure than to identify the single best option available.
		An essential piece of advice is to carefully isolate the implementation of the dictionary data structure from its interface.
