Relational Databases Lee Rudd Abstract Data for our programs are stored in various formats. The most commonly used format is in the form of a database since databases are not dependent on a single program or hardware platform. These databases are stored in five structures of hierarchical‚ network‚ relational‚ multidimensional‚ and object-oriented. Hierarchical structure organizes data in a one to many relationship. The network goes of the hierarchical structure by organizing data in

there has been a controversial issue dealing with building a national DNA database. This issue has been brought up over the discussion of the actual database and what kinds of effects will come out of it‚ if it actually happens to go through. Some people think the database will be a force in crime fighting. Others think it is a violation of civil liberties. In the early 1900s‚ “fingerprinting‚” a new crime-fighting database‚ was developed. With the exception of identical twins‚ no two people have

1. Advantages of database over Advantages of spread sheets; One of the advantages of database is that it reduced data redundancy this is because in databases‚ there is an identifier. The identifier is the primary key‚ where when it is entered‚ all other details‚ which saved under the primary key‚ will be revealed. Therefore‚ there’ll be less repetition of data. Next‚ databases improved data integrity‚ which it will guaranteed the data proven to be correct. Linked to the primary key function‚ the

Vernacular architecture Ronald Brunskill defined it accurately in saying: “A building designed by an amateur without any training in design; the individual will have been guided by a series of conventions built up in his locality‚ paying little attention to what may be fashionable. The function of the building would be the dominant factor‚ aesthetic considerations‚ though present to some small degree‚ being quite minimal. Local materials would be used as a matter of course‚ other materials being

Gothic Architecture Gothic Architecture is a very interesting topic that I chose because of its unique style. It was originated in the 12th century France to the 16th century‚ and it was also known as Frankish work.

Allen) “A diagram architecture is not necessary an architecture produced through diagrams.... Instead‚ diagram architecture is an architecture that behaves like a diagram‚ indifferent to the specific means of its realization." (Par. 13) This paragraph points out the answer that beginners architecture students struggled to find. In the process of design‚ I try to find the potential through the translation from reality to the abstract diagram. While I wonder if the architecture should carefully be

Geometry PJ Architecture and Geometry Architecture and geometry are perfect complements of each other they go hand to hand in so many ways let’s discuss some of these ways. Architecture has geometry written all over it if geometry never existed Architecture wouldn’t have existed either. First of all geometry is the reason that we can calculate and measure the sizes and shapes of certain structures for us to use. Geometry allows us pin point exactly how much more we may need or less ‚ without
