HC1041 IT for Business: Discussion on Databases, Data Marts, and HTML

This assignment delves into three key areas of Information Technology for Business. It begins by examining Object-Oriented Databases (OODB), highlighting their advantages such as extensibility, improved performance, and enriched modeling capabilities, while also acknowledging disadvantages like lack of standardization and complexity. The discussion then shifts to data marts, defining them as specialized subsets of data warehouses designed to serve specific user groups within an organization. Finally, the assignment touches upon HTML (HyperText Markup Language), emphasizing its crucial role in web development for creating and structuring web documents using tags and attributes. This provides a foundational understanding of these technologies within a business context. Desklib offers a wealth of similar solved assignments and past papers to aid students in their studies.

Question 1
Object-Oriented Database (OODB) has booth advantage and disadvantages. The advantages
include extensibility, improved performance, and enriched modeling capabilities, applicability to
advanced applications, support for long-duration, support for schema evolutions and capability to
handle a large variety of data types. On extensibility, this type of database allows one to build
other data types from already existing data types. OODB also enables easy modeling of the ‘real
world.' The advantages of OODB include lack of support in terms of security, complexity,
competition, lack of standards, lack of experience and lack of universal data model, (Ogunlere
and Idowu, 2015). OODB do not have a data model that has universally agreed upon and most of
the available models do not have a strong theoretical foundation. Also, they are more complex
compared to other types of databases and also the use of OODB is not popular with some people
not accepting it.
Question 2
A data mart is the access layer of a data warehouse that is used to provide users with data. A data
mart is different from a data warehouse and it can generally be said to be a subset of a data
warehouse. A data mart serves a storehouse of data that serves a specific community and it is
specifically designed to meet the needs of a specific group of users, (Jukic, Vrbsky, and
Nestorov, 2016). For example, a data mart can only serve the sales or finance department of an
organization. On the other hand, a data warehouse is a central repository for all historical data of
an organization.
Question 3
HTML refers to HyperText Markup Language. HTML is very important and is needed in the
Web since it is used to create documents on the Web. HTML uses attributes and tags to define
and structure the web document layouts.
