Access database design and programming by Steven Roman

By Steven Roman

I've been utilizing entry and VBA for many years, with none formal education in relational database or programming. during this concise ebook, Steven Roman controlled to provide a robust starting place within the conception of relational databases, VBA and DAO.

Armed with this information, I now have the boldness to dig deeper in those 3 themes and research extra complicated material.

One draw back even though: i discovered the final a part of the e-book on ADO really complicated. Steven Roman prefers DAO to ADO and it shows.

I however provide the ebook five stars, because the first 3 components of the e-book are stellar.

Ak} {B} For instance, it is probably safe to say that: {PubName,PubPhone} {PubID} which is just another way of saying that there is only one publisher with a given name and phone number (including area code). It is very important to understand that a functional dependency means that the attributes on the left completely determine the attributes on the right for now and for all time to come, no matter what additional data may be added to the database. Thus, just as the concept of a key relates to entity classes (table schemes) rather than individual entity sets (tables), so does functional dependency.

More specifically, CityPopulation is strictly an informational attribute (not for identification of houses), but it gives information about cities, not house addresses. Thus, this table scheme is not in second normal form. We can be a little bit more formal about the meaning of second normal form as follows. Referring to the previous example, we have the dependency: {City} {CityPopulation} where CityPopulation does not belong to any key, and where City is a proper subset of a key, namely, the key {City, Street, HouseNumber}.

In other words, the informational 51 TEAM FLY PRESENTS attributes provide information specifically about the entities in this entity class and not about some other entities. Let us illustrate with an example. Consider a simplified table scheme designed to store house addresses. One possibility is: {City,Street,HouseNumber,HouseColor,CityPopulation} The CityPopulation attribute is out of place here because it is an attribute of cities, not house addresses. More specifically, CityPopulation is strictly an informational attribute (not for identification of houses), but it gives information about cities, not house addresses.
