| Question | Answer |
|---|---|
| variables | Named memory holders that contain numbers like ints or doubles can have mathematical operations performed with them just like numbers themselves can |
| access modifiers | are words that go before the declaration of a variable that govern whether or not different types of class files outside of the containing file can see these variables; typically "public" or "private" |
| flowchart | using the diamond shape, arrows, rectangles and other shapes you can make one of these to show the flow of logic in a given process or method or class. |
| private | is an access modifier that indicates that the containing class and ONLY the containing class can see a variable or property directly |
| public | is an access modifier that indicates ANY class, not just the containing one, can directly see and use or alter that variable or property; this means sub-classes, other unrelated classes or just other classes in a project |
| asynchronous | these are method calls that are processed in a separate thread from the main application thread; this speeds up a web page to do other things while the asynchronous call can handle its own tasks separately. |
| Application improvement | this means improving the software by: •the way it is organized •what types of languages it uses •using different software programs on the server It does NOT mean making changes to any of the involved hardware or the network connection |
| invoke | means to call something to start it, such as a web service or a method |
| Console.Write | is the library method of the Console object that C# uses to output to the console like Java uses System.out.println |
| * | an SQL wildcard character that means to select all the data available in a table; it means to include every column heading when executing a query |
| ORDER BY | an SQL command indicating to arrange the data returned from a query statement in a particular sequence |
| SQL | a very common query language that is used to ask questions to a database to get specific answers back that contain data needed to answer the question |
| transaction statement | using one of these in SQL means that all the changes requested by a statement must actually execute without any error or all the changes will be canceled and the entire database will go back to the way it was before the statement was attempted |
| normalization | this is done to a database to reduce redundant data in it; it results in a faster running database, a smaller database and an easier to maintain database; it does NOT increase the size of the database |
| pooling | is done with database connections to speed up the process of connecting to a networked multi-user environment; connections are a time-intensive process and are done ahead of time with users just approved to use an existing connection for speed's sake |
