· The database may hold some information as rules rather than tables (eg the 'forebear' relation we used in examples
· Only need one language. RDBMS often use two languages, COBOL to code the program, and another language to interface with the user (SQL).
· May do complicated analysis of data

5 What advantage is there to using algebraic equations instead of numerical values when defining the dimensions of a CAD model?
Using algebraic equations allows for greater flexibility and scalability in defining the dimensions of a CAD model. By using variables instead of fixed numerical values, the model can be easily adjusted and adapted to different sizes or configurations without having to manually change each individual dimension. Additionally, algebraic equations enable parametric modeling, where changes to one dimension automatically update all related dimensions, saving time and reducing errors in the design process.
How do you value an option?
Options are valued using a theoretical model known as the "Black Scholes Model". The black scholes model prices options based on what are known as "Greeks", which are mathematical parameters of variables that influences the price of an option. However, this is a theoretical model because it cannot take into consideration the actual supply and demand of an option in the market and such forces does take the price of an option away from their theoretical value.

How are options priced?
Options are priced using a theoretical model known as a "Black Scholes Model". The black scholes model price options based on a set of mathematical parameters known as the "greeks" which covers the variables that influence options prices. However, this is only a theoretical model because it cannot take into consideration the actual demand and supply condition of specific options in the market. Actual demand and supply most often move the price of an option away from its theoretical value.
Does the constant growth model takes into consideration the capital gains earned on a stock?
Yes, the constant growth model, also known as the Gordon Growth Model, considers capital gains indirectly through the expected growth rate of dividends. It assumes that dividends will grow at a constant rate over time, and since stock prices generally reflect the present value of future dividends, any expected growth in dividends contributes to potential capital gains. Therefore, while the model primarily focuses on dividend income, it inherently accounts for capital gains through the growth rate of those dividends.

Limitations and benefits of rational database model?
One of the advantages of a relational database model is that the broken keys and records and the data complexity are usually simplified. The disadvantage of the relational database model is that it requires sophisticated processing power which is very costly.
What are the advantages and disadvantages of prototyping model?
One advantage of prototyping is the fact that you can make changes to the model before building the actual model. One disadvantage of prototyping is that it can take too long.
Advantage of relational model over hierarchical model?
Use of primary keys less data redundancy compatible with inconsistencies associated with database anomalies
What is the most popular database model?
Relational Database Model
Advantages and disadvantages of build and fix model?
You can get all of the work done before fixing it. This makes it easier to see the mistakes as a whole.
What is database model?

What is a good way to represent a database?
Relational model of database is a good way to represent the database. Also network data model and hierarchical model can be used depending on the requirements.
What is the difference between data model and database model?
A database is a collection of tables that is used for some purpose (typically an application of some sort). A database model is a description of that database, and describes how the tables relate to each other. Typically, a model is designed first, then the actual database is implemented using the model as a blueprint.
What are the advantages and disadvantages of Associative model?
With the Associative model there is not record. When assembling all of the current information on a complex order the data storage needs to be re-visited multiple times. This could pose as a disadvantage. Some calculations seem to suggest that Associative database would need as many as four times the data reads as the relational database.
