• With In-memory processing the source database is queried only once instead of accessing the database every time a query is run thereby eliminating repetitive processing and reducing the burden on database servers. • By scheduling to populate In-memory database overnight the database servers can be used for operational purposes during peak hours. Disadvantages of In-memory BI • With increase in number of users and data volumes the amount of RAM needed also increases which in turn affects the hardware costs. Who is it for? While In-memory processing has a great potential for end users it is not the answer to everyone. Important question organizations need to ask is if slower query response times are preventing users from making important decisions. If company is a slow moving business where things don’t change often then in-memory solution is not effective. Organizations where there is a significant growth in data volume and increase in demand for reporting functionalities that facilitate new opportunities would be a right scenario to deploy in-memory Business

Even though some people believe repressed memories should stay hidden because it would only hurt the person that it belongs to, I think it is better to have the memory and deal with it, and not having a piece of your life missing. A situation I can think of comparing this to would be another incident of memory failure.

    The biological approach to the basis of memory is explained in terms of underlying biological factors such as the activity of the nervous system, genetic factors, biochemical and neurochemicals. In general terms memory is our ability to encode, store, retain and recall information and past experiences afterwards in the human brain. In biological terms, memory is the recreation of past experiences by simultaneous activation or firing of neurons. Some of the major biopsychological research questions on memory are what are the biological substrates of memory, where are memories stored in the brain, how are memories assessed during recall and what is the mechanism of forgetting.

    Introduction According to information processing model, short term memory has a limited capacity to hold information (Atkinson & Shriffin, 1968). The span of short term memory is said to be limited to about seven items (+2) (Miller, 1956 as cited in Terry, 2000). Short-term memory is also an active memory where we do our active memory processing (Lefrancois, 2000).
