This document discusses entity relationship (ER) models. It describes ER models as concise descriptions of user data requirements that help visualize entities and relationships in a domain. The basic elements of an ER model are entities, attributes, and relationships. An example ER model is presented for a student academic information system that models students, courses, professors, labs, and projects as entities and how they relate. Key concepts like entity sets, relationship types, participation constraints, and weak entity types are also explained.
The document provides an overview of caching in ASP.NET, including output caching to cache entire pages, fragment caching to cache parts of pages, and data caching to cache application data in memory for faster access. It discusses using the @OutputCache directive and Cache object to control caching along with settings like duration, location, and varying caches based on parameters or headers. Caching can improve performance and scalability by reducing server response times and CPU loads but requires testing to identify benefits and avoid hidden problems.
The document provides examples of different types of plays and playwrights including:
- Playwright Marc Blitzstein and his play The Cradle Will Rock from 1938
- Playwright E.E. Cummings and his play Santa Claus: A Morality from 1946
- Playwright Robert Browning and his closet drama Pappi Passes from 1841
- Playwright Joseph Hardy and his romantic comedy Broadway from 1979
It also lists stock characters such as Nazis, jocks, and nerds and defines the term "hubris" but does not provide a completed example for each literary term category such as high comedy, low comedy, classical tragedy, or revenge tragedy.
