    Why Distance Counseling Works
    Isn’t it true that when admission officers evaluate student applications they really don’t know the student? Other than the interview that some colleges offer, acceptance decisions are based on a written document, the application. For students to portray themselves in the best light, their GPA’s, test scores, essays and recommendations must paint the best possible picture. In addition to local students, I am currently working with students and families in 16 states and 5 count

    Telecom Expense Management Defeats Billing Errors
    How do you tell if your company's telecom bill is correct? Even a home phone bill can be so intimidating that most people just pay it without much inspection. According to the Aberdeen Group, telecom is one of the largest and most poorly organized spend categories in most companies. Eighty-five percent of telecom invoices are not audited, even though seven to twelve percent of all charges are in error, which indicates the pressing need for better telecom expense management.The design principles of the dimensional model, which is commonly used in data warehousing, are described in this article series. Dimensional models capture business performance measurements, which are used to support decision making. Dimensional model The descriptive simplicity and high performance in query execution, are characteristics which have contributed to the increased use of the dimensional model in data warehouse infrastructures. The symmetry and descriptive simplicity can be seen at the conceptual model (see resource link) which relates to retail sales monitoring (data warehousing technology has been introduced initially in retailing).

    Relational data models are use to implement the above conceptual model (as depicted in the resource link).

    This model is easily understood by Business analysts, in contrast with other operational systems models (‘normalized data models’ in relational modeling language). In a relational modeling representation, the model in its simple form, consists of a central ‘fact table’ and ‘dimension tables’ which are connected to the ‘fact table’ via reference keys (fo

    How to Make a Career - Life Change
    Have you’ve felt like your job doesn’t match your talents, skills and attributes with who you are and what you’re doing? Have you wanted to make a career/life transition, and don’t know where to start? Let’s take a look at the topics to consider making a life/career change. Making a career/life change is a process. It isn’t something you can think about for a few hours that will result in your “dream job”. Sometimes we want the life/career change to be fulfilled quickly, a

    A Strategic Look At Do's and Don'ts of Board Meeting Minutes
    Do you serve on a board of directors and experience significant inaccuracies and inconsistencies in board minutes? Do you know that board minutes are really a very important resource to governing boards? Minutes of board meetings provide evidence that a board has exercised care in decision-making. The minutes also substantiate that a board is operating in accordance with its Bylaws and other documents and rules.Although there is recognition that board minutes are imp

    The Two Faces of Unemployment
    What does it really mean when unemployment is discussed?There is unemployment and there is being unemployed. Being unemployed is simply not having work when a person is willing to work. Unemployment is a little broader in scope and what we will concentrate on. Unemployment is being without work or related to a job loss.The Two Faces of Unemployment comprise the positive aspects and the negative aspects. Most of us are very aware of the negative aspects such as

    The Great Freelance Boom
    Before the turn of the new millennia, freelancing in any field was thought of as being for those who absolutely do not want to deal with a boss, but who do not get paid squat. To an extent, that belief is still apparent today even though the whole concept of freelancing has changed completely.These days, there are an abundance of freelancers in virtually any field, but the surprise is that there are even more jobs available to these freelancers than ever before. Plus,

In a relational modeling representation, the model in its simple form, consists of a central ‘fact table’ and ‘dimension tables’ which are connected to the ‘fact table’ via reference keys (foreign keys in relational modeling language). This form is called ‘star schema’. Fact table The ‘fact table’ is the central table in a dimensional model, which stores the measurements (facts) on which analytical processing takes place. All measurements adhere to the same level of detail. The most useful measurements are usually additive or semi-additive, in order to allow analytical processing (numerical calculations which produce additional ‘derived’ facts). During analytical processing, thousands or millions of fact rows are retrieved and numerical processing is applied on facts or fact combinations. Facts which are stored in a fact table, should be captured at the most detailed (or most granular) level (also called ‘atomic level’, meaning something that cannot be divided). On the other hand, maintaining aggregate facts, limits the analysis (or drill down) capability on certain d
