This project includes a SQL Server database and a Visual Studio project that simulate the transactions at a chain of grocery stores. It has stores, employees, products, ingredients in the products, manufacturers, and brands. When the simulation runs it generates customer transactions, employee work history, store history (open/closed/on fire/etc.), coupons, coupon usage, and product price history. As this data accumulates you can use it to teach SQL programming and query design.
The source code for the simulation project is included and can be used as an object lesson for software development courses, particularly C# and OOP.

The foreground Veil of material that lies in front of the Orion Nebula is the best studied sample of the interstellar medium because we know where it is located, how it is illuminated, and the balance of thermal and magnetic energy. In this work, we present high-resolution STIS observations toward the Trapezium, with the goal of better understanding the chemistry and geometry of the two primary Veil layers, along with ionized gas along the line of sight. The most complete characterization of the rotational/vibrational column densities of H2 in the almost purely atomic components of the Veil are presented, including updates to the Cloudy model for H2 formation on grain surfaces. The observed H2 is found to correlate almost exclusively with Component B. The observed H2, observations of CI, CI*, and CI**, and theoretical calculations using Cloudy allow us to place the tightest constraints yet on the distance, density, temperature, and other physical characteristics for each cloud component. We ﬁnd the H2 excitation spectrum observed in the Veil is incompatible with a recent study that argued that the Veil was quite close to the Trapezium. The nature of a layer of ionized gas lying between the Veil and the Trapezium is characterized through the emission and absorption lines it produces, which we ﬁnd to be the blueshifted component observed in S III and P III absorption. We deduce that, within the next 30–60 thousand years, the blueshifted ionized layer and Component B will merge, which will subsequently merge with Component A in the next one million years.
In an effort to promote an image of Allied unity on the eve of Operation Overlord, the Allied invasion of Western Europe, a Joint Anglo-American Film Commission was established with the goal of making a series of short documentaries on the liberation of the continent. Unfortunately, despite the prior planning, the plans for a series of joint films fell victim to competing ideologies about how to showcase the allied campaign. In an effort to salvage the situation the American film maker George Stevens was brought in to make a single long documentary, highlighting the campaign from D-Day to VE-Day. The resulting film, The True Glory, won an Oscar for best documentary of 1945, but in fact was the result of a failure of Allied film propaganda policy.
