The glossary includes definitions of terms used in the statements in the framework. These terms are defined for readers of the framework and are not necessarily intended to be the definitions or terms that are seen by students.
Data Types and Data Structures
In this post we will be looking briefly at, and at a high-level, the various data types and data structures used in designing software systems, and from which specific types of algorithms can subsequently be built upon and optimized for. There are many data structures, and even the ones that are covered here have many nuances that make it impossible to cover every possible detail. But my hope is that this will give you an interest to research them further. A data type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. An abstract data type ADT describes the expected behaviour associated with a concrete data structure.
Heap (data structure)
In computer science , a data structure is a data organization, management, and storage format that enables efficient access and modification. Data structures serve as the basis for abstract data types ADT. The ADT defines the logical form of the data type. The data structure implements the physical form of the data type. Different types of data structures are suited to different kinds of applications, and some are highly specialized to specific tasks. For example, relational databases commonly use B-tree indexes for data retrieval,  while compiler implementations usually use hash tables to look up identifiers. Data structures provide a means to manage large amounts of data efficiently for uses such as large databases and internet indexing services.
The Dictionary of Algorithms and Data Structures DADS is an online, publicly accessible dictionary of generally useful algorithms, data structures, algorithmic techniques, archetypal problems, and related definitions. In addition to brief definitions, some entries have links to related entries, links to implementations, and additional information. DADS is meant to be a resource for the practicing programmer, although students and researchers may find it a useful starting point. DADS has fundamental entries in areas such as theory, cryptography and compression, graphs, trees, and searching, for instance, Ackermann's function, quick sort, traveling salesman, big O notation, merge sort, AVL tree, hash table, and Byzantine generals. DADS also has index pages that list entries by area and by type. Currently DADS does not include algorithms particular to business data processing, communications, operating systems or distributed algorithms, programming languages, AI, graphics, or numerical analysis.
A data structure is a particular way of organizing data in a computer so that it can be used effectively. For example, we can store a list of items having the same data-type using the array data structure. This page contains detailed tutorials on different data structures DS with topic-wise problems.

Development of this dictionary started in under the editorship of Paul E. This is a dictionary of algorithms, algorithmic techniques, data structures, archetypal problems, and related definitions. Algorithms include common functions, such as Ackermann's function.
In computer science , a heap is a specialized tree -based data structure which is essentially an almost complete  tree that satisfies the heap property : in a max heap , for any given node C, if P is a parent node of C, then the key the value of P is greater than or equal to the key of C. In a min heap , the key of P is less than or equal to the key of C. The heap is one maximally efficient implementation of an abstract data type called a priority queue , and in fact, priority queues are often referred to as "heaps", regardless of how they may be implemented. In a heap, the highest or lowest priority element is always stored at the root.
The Algorithm Design Manual pp Cite as. Changing a data structure in a slow program can work the same way an organ transplant does in a sick patient. Important classes of abstract data types such as containers, dictionaries, and priority queues, have many different but functionally equivalent data structures that implement them. Changing the data structure does not change the correctness of the program, since we presumably replace a correct implementation with a different correct implementation. However, the new implementation of the data type realizes different tradeoffs in the time to execute various operations, so the total performance can improve dramatically. Like a patient in need of a transplant, only one part might need to be replaced in order to fix the problem.
