This is known as azimuth - if an object isat an azimuth of 45 degrees it is in the Northeast direction relativeto an observer. AzimuthRange shows the TOTAL arc the sun traverses in the sky each day.On February 14, the sun rises (comes above the horizon) at an azimuthof 131.4 degrees and sets (goes below the horizon) at an azimuth of229.3 degrees in Barrow, Alaska. This gives an Azimuth Range (thedifference between the sunrise and sunset azimuth) of 97.9 degreesfor that day.The graph belowshows the Azimuth Range, in degrees, the sun traverses in the skyeach day in Barrow, Alaska.Use the informationabove to answer the following questions in complete sentences. According to the graph, what is the sun doing in the first, horizontal part (A)? What does the second, inclined part (B), of the graph signify? What is happening in the third, horizontal part (C), of the graph? Describe each lettered part of the graph in terms of its slope. (Remember, slope equals rate of change.) A. B. C.

  • Extend the curve of part B so that it intersects both the x and y-axis. What is the x-intercept of B and what is its meaning?

  • What is the y-intercept of B and what is its meaning? a) What is the equation of line A? b) What is the equation of line C? Name two ordered pairs on curve B. Using the ordered pairs, write the equation of the line that fits B.

Predict what the graph will do next, after part C. Why? Table ofContents

CsiDb is a C++ library that was developed for internal use at Thomson Reuters in one of its Creative Solutions line of desktop accounting applications. It is part of a software layer that mediates access to an underlying SQL DBMS. It augments an older in-house object-relational mapping subsystem. The latter system was considered capable for database updates, providing reasonable ease of use to the application developers, as well as a layer that could enforce complex business rules that could not be readily expressed directly by the DBMS. However, the object-relational subsystem was a performance bottleneck when reading data, in part because it made it cumbersome to tailor data views to specific application needs. CsiDb was an answer to this problem, providing application developers with a library interface that allowed them to build custom queries more easily and dynamically (the form of queries depending e.g. on user input), without themselves having to learn an antiquated and anemic dialect of SQL, and often without waiting for the few available database experts on the development team to design views and add them to the schema.


I read Date and Darwen's "A Guide to the SQL Standard" in 1998 and its precise, concise description of an SQL with features far beyond those implemented by any existing product inspired me to develop ThinkSQL ( ) - an SQL server with powerful constructs from the latest standard. The criticisms of the language in the guide hinted at a better way, and reading Foundation for Future Database Systems (The Third Manifesto) (Second edition). Addison-Wesley (2000) (TTM) certainly provided the details. It took several readings to fully understand the scope of the shift.
