NORMALIZATION TUTORIAL (EXTRA) 1. Given the dependency diagram‚ answer items a-c: [pic] a. Identify and discuss each of the indicated dependencies. C1 ( C2 represents a partial dependency‚ because C2 depends only on C1‚ rather than on the entire primary key composed of C1 and C3. C4 ( C5 represents a transitive dependency‚ because C5 depends on an attribute (C4) that is not part of a primary key. C1‚ C3 ( C2‚ C4‚ C5 represents a set of proper functional

constructing of Relational Database using an EER Model 4.1 The steps involved in the design of relational database are 1) Developing the conceptual model – Drawing the ER/ EER diagram 2) Transforming the Conceptual model into a set of relations – relational schema and 3) Normalizing the relations. Once ER / EER model has been developed for the application ‚ ER/ EER diagram can be mapped into a relational model . ER/ EER diagram consists of the following components. 1)

The free group with two generators a and b is composed of all finite strings that are formed from the four symbols a‚ a−1‚ b and b−1 given that no a is directly next to an a−1 and no b is directly next to a b−1. Two such strings can be concatenated and converted into a string of this type by repeatedly replacing the "forbidden" substrings with the empty string. For example: abab−1a−1 concatenated with abab−1a yields abab−1a−1abab−1a‚ which contains the substring a−1a underlined in the example‚ and

An entity set that does not possess sufficient attributes to form a primary key is called a weak entity set. One that does have a primary key is called a strong entity set. For example‚ The entity set transaction has attributes transaction-number‚ date and amount. Different transactions on different accounts could share the same number. These are not sufficient to form a primary key (uniquely identify a transaction). Thus transaction is a weak entity set. For a weak entity set to be meaningful

Data Marts Advantages The implementation of data marts enable users to gain faster access to common data utilizing a technique called dimensional data modeling‚ which optimizes data for reports. For example‚ since data is prepared in common format‚ users with little or not training at all‚ can browse a data mart and obtain information as needed. Data marts can improve end user response time‚ as it contains raw data which allows computer systems to focus on a single task‚ thus‚ improving performance

There are 4 major types of bridges. We have a separate page for each type of bridge. Please go to one of the following pages. Beam - The beam type is the simplest type of bridge. The beam bridge could be anything as simple as a plank of wood to a complex structure. It is made of two or more supports which hold up a beam. Arch - In the arch type of bridge‚ weight is carried outward along two paths‚ curving toward the ground. Suspension/Cable-stayed - The deck (trafficway) of a suspension bridge
