Efficiency can be defined as a measurement of the average execution time and memory space which is required by an algorithm (program) to complete work on a set of data. Efficiency of an algorithm is usually characterized by its order. (Daintith 2004).
Big-O notation is used to…
In the context of the above brief discussion, Big O notation can be defined as a description of the growth rate of the order of a function T(N) as N becomes very large (Ellard 1997).
In C++, the only difference between classes and structures is that all the members and base classes in structure are public by default, whereas, classes have private members and base classes by default.
Dynamic Objects are those objects whose lifetimes are independent of the existence of the scope in which they were created and therefore, they give programmers a greater flexibility in managing the objects (Kafura 1996).
In C++, a dynamic object can be created using a “new” operator which returns a pointer to a newly constructed object. On the other hand, to destruct a dynamic object in C++, a “delete” operator is used which takes an argument of a pointer variable that holds the pointer to the object that is returned by the “new” operator at the time of creating a dynamic object (Kafura 1996).
The free store is a dynamic memory area which is available to allocate (by using the “new” operator) and deallocate (by using the “delete” operator) storage for objects during the execution of the program.
A “null pointer” is a special kind of pointer which is distinguishable from all other pointer values and is not the address of any object or function. It is used to refer to the pointer which is “not allocated” or “not pointing anywhere yet”. However, it is important to note that a null pointer is not the same as an uninitialized value (Summit 1994).
(a) A destructors is the special kind of function with the same name as its class prefixed by a ~ (tilde) which is called for a class object to deallocate memory and do other cleanup for a class object and its class members when the object passes out of scope or is explicitly deleted. For example:
An AVL tree, also called height balanced, is ...

Therefore it is scientific that a true data mining software application or technique must be able to change data presentation criterion and also discover the previously unknown relationships amongst the data types. Data mining tools allow for possible prediction of the future trends and behaviors, hence enabling for formation of proactive, knowledge-driven decisions.
ABSTRACT DATA STRUCTURES Introduction A data type is acknowledged as an abstract data type when it is expressed in terms of processes on it, and its implementation is concealed (with the intention that it can be replaced with another application such as effectiveness purposes, as well as this will not change anything in the existing computer program).
Interoperability has enhanced the patient care and efficient research against diabetes and other health related disorders. But, diabetes data sharing and interoperability is associated with some critical issues including privacy and security of data and data management system, interface problems and usage of legacy systems.
Interviews can be used as a technique to ensure that a manager hires qualified employees in the firm. Interviews are defined as meaningful conversations between an interviewer(s) and a respondent(s) where the latter is asked a set of questions by the former in an effort to acquire knowledge on a particular subject (Oatey, 1999).
The transcription protocol was done on an informal basis. It was more of a conversational and on a one on one private setup. Both the interviewer and the respondent were very responsive to one another's overtures. Based on the interview, the Executive divulged his major concerns to affecting his company.
The assignment involves producing a database application and specifying a logical schema describing the data, giving a physical schema of the database, and also giving the relational table definitions written in SQL.
The database is to be used for answering random queries, primarily about the number and quality of protein structures that have been released by different individuals and institutions.
