IT for Business2 IT for Business 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.
