Storing Organizational Information-Database
1.Descride two primary method of
integriting information across multiple database?
Firstly forward integration takes
information entered into a given system and send it automatically to all
downstream system and process.Secondly backward integration takes information
entered into given system and send it automatically to all upstream system and
process.
2.Describe the benefit of
data-driven web site ?
Allow the website owner to make
changes any time,a statis website requires a programmer to make updates,having
a data-driven website enables to site to grow faster than would be possible
with a static site and even the most competent programmer charged with the task

which information is stored.Attributes also called fields or colums are
characteristic or properties of an entity class.Secondly keys and relationships.
4.Evaluate the advantages of the
rational database model?
Firstly increase
flexibility.increased scalability and performance,reduced information
redundancy,increased information integrity(quality) and increased information

dimensional of information at one time.In a database warehouse and data marts
information is multidimensional it contains layers of colums and rows.Each
layer in a data warehouse or data marts represents information according to an
additional dimension.Dimensions could such things as
