Cloud Intelligence. There are 3 new things in the cloud intelligence compared to the old business intelligence. 1. Elasticity Dynamic on-demand pro-visioning of resources. For cloud computing‚ this term has mostly been used in relation to scaling up/down the performance‚ e.g.‚ the number of processing nodes. While this form of elasticity is obviously also relevant for cloud intelligence‚ an even more important type of elasticity is the ability to dynamically bring in new data sources to meet

Normalization Normalization is a method for organizing data elements in a database into tables. Normalization Avoids • Duplication of Data – The same data is listed in multiple lines of the database • Insert Anomaly – A record about an entity cannot be inserted into the table without first inserting information about another entity – Cannot enter a customer without a sales order • Delete Anomaly – A record cannot be deleted without deleting a record about a related entity.

The entity-relationship model (or ER model) is a way of graphically representing the logical relationships of entities (or objects) in order to create a database. entity type is a collection of entity instances sharing similar properties Strong Entity Vs Weak Entity An entity set that does not have sufficient attributes to form a primary key is termed as a weak entity set. An entity set that has a primary key is termed as strong entity set. A weak entity is existence dependent. That is the

Multiple Intelligences and Emotional Intelligence those writers David Miller Sadker and Myra Pollack Sadker claims that intelligent test is not mental for it is cultural. “Some of us grew up in communities where IQ was barely mentioned.”(p77)The world intelligence does not have universal meaning. In one culture doing something is taken as intelligent task whereas the something turns — to be valueless for the other. Therefore instead of single intelligence there are multiple intelligences.

NORMALIZATION OF DATABASE NORMALIZATION- is the process for evaluating and correcting table structures to minimize data redundancies‚ thereby‚ reducing the livelihood of data anomalies. The normalization process involves assigning attributes to tables based on the concept of determination. Normalization works through a series of stages called normal forms. 3 Stages of Normalization 1. 1NF or FIRST NORMALIZATION FORM 2. 2NF or SECOND NORMALIZATION FORM 3. 3NF or THIRED NORMALIZATION

Although‚ data is separated into different and more complex tables during normalization‚ the process of normalizing a database can help to organize data more efficiently by minimizing redundancy and providing more accurate records. During the process‚ column and field names are consolidated into more specific ones to avoid repetition of data. In many cases‚ tables are divided into two or more tables and linked via a relationship using their Primary Keys and/or Foreign Keys. The main goal is to
