1. Investigate the different approaches an RDBMS can take to implementing relational views. What approaches do the major commercial RDBMS take?

2. Investigate one of the many data models not discussed in this chapter, critically evaluating its potential for use in web database applications. Possible data models for investigation include the associative data model (see www.lazysoft.com/index. html), object-orientated and object-relational data models (Date (2004) or Elmasri & Navathe (2007) are good starting points.)
