In-memory is important for performance, but it takes a lot more to deliver a Business Discovery platform. Traditional BI based on queries and cubes may run in memory for faster response time, but they still require IT to manually maintain the data associations users depend on. It’s what QlikView does with in-memory technology that really makes a difference. When a QlikView document is published on a QlikView Server, the content it contains becomes available for consumption by any user with privileges to access it. • When a user first opens a QlikView document, data is loaded in memory. The compressed and unaggregated dataset is loaded off the disk and into the QlikView Server’s RAM (random access memory). • Users explore data via selections. Central to QlikView is the concept of a user-defined selection state. As users click around in a QlikView document, they indicate which subsets of data they are interested in analyzing and which subsets should be ignored. QlikView takes advantage of the highly indexed nature of the unaggregated dataset. QlikView dynamically presents a subset of all the data available to the QlikView document based on the selection state. This happens in real time as the user executes clicks. • Upon selection, aggregates render instantly. On the fly, QlikView renders aggregates as intuitive and interactive user interface objects: charts, graphs, tables,etc. Users interact with objects in QlikView documents through any supported client.Users can create their own objects using the collaboration features of QlikView.
Nursing theory is the term given to the body of knowledge that is used to support nursing practice. Nursing theory is a framework designed to organize knowledge and explain phenomena in nursing, at a more concrete and specific level. Theory-guided, evidence-based practice is the hallmark of any professional discipline. Almost 90% of all Nursing theories are generated in the last 20 years. A paradigm is a model that explains the linkages of science, philosophy, and theory accepted and applied by the discipline. Recipient of care, including physical, spiritual, psychological, and sociocultural components. Actions, characteristics and attributes of person giving care. Concepts are the building blocks—the primary elements—of a theory. Constructs are concepts developed or adopted for use in a particular theory. The key concepts of a given theory are its constructs. They epresent ways of thinking about a problem or ways of representing how complex things work the way that they do.
Models may draw on a number of theories to help understand a particular problem in a certain setting or context. They are not always as specified as theory. Variables are the operational forms of constructs. They define the way a construct is to be measured in a specific situation. Match variables to constructs when identifying what needs to be assessed during evaluation of a theory-driven program.

Orem’s Self care deficit theory in nursing Self-care maintains wholeness. Nursing is using knowledge for human betterment. Individuals maintain stability and balance through adjustments and adaptation to the forces that impinges them. Individual as a behavioural system is composed of seven subsystems. Attachment, or the affiliative subsystems – is the corner stone of social organisations. Behavioural system also includes the subsystems of dependency, achievement, aggressive, ingestive-eliminative and sexual. Disturbances in these causes nursing problems. The individual is a biopsychosocial adaptive system within an environment. The individual and the environment provide three classes of stimuli-the focal, residual and contextual. Neuman’s model includes intrapersonal, interpersonal and extrapersonal stressors.
Nursing is concerned with the whole person. Nursing actions (Primary, Secondary, and Tertiary levels of prevention) focuses on the variables affecting the client’s response to stressors. Imogene King’s Goal attainment theory Transactions provide a frame of reference toward goal setting. A conceptual model of nursing from which theory of goal attainment is derived. From her major concepts (interaction, perception, communication, transaction, role, stress, growth and development) derived goal attainment theory. ·Perceptions, Judgments and actions of the patient and the nurse lead to reaction, interaction, and transaction (Process of nursing). Nancy Roper, WW.Logan and A.J.Tierney A model for nursing based on a model of living Individuality in living. A conceptual model of nursing from which theory of goal attainment is derived.
