• NoSQL vs Relational Coding Styles

  - by Chris Henry

  When building objects that make use of data stored in a RDBMS, it's normally pretty clear what you're getting back, as dictated by the tables and columns being queried. However, when dealing with NoSQL, document-based systems, it's less clear what is being retrieved. What are common methods of keeping track of structure in which data is stored?

• Accessing Arbitrary Columns from an R Data Frame using with()

  - by johnmyleswhite

  Suppose that I have a data frame with a column whose name is stored in a variable. Accessing this column using the variable is easy using bracket notation: df <- data.frame(A = rep(1, 10), B = rep(2, 10)) column.name <- 'B' df[,column.name] But it is not obvious how to access an arbitrary column using a call to with(). The naive approach with(df, column.name) effectively evaluates column.name in the caller's environment. How can I delay evaluation sufficiently that with() will provide the same results that brackets give?

• Centralizing / Abstracting MSSQL Data from Multiple Tables / Databases

  - by davemackey

  If one has a number of databases (due to separate application front-ends) that provide a complete picture - for example a CRM, accounting, and product database - what methods are available to centralize/abstract this data for easy reporting? Essentially, I'm wondering if there is a way to automatically pull data from multiple databases into a central repository that is continuously updated from the three databases and which can be used for reporting? I'm also open to alternative best practice suggestions?

  It starts to bore me that I always have to ask questions about trifles.

I can then start playing around with the data in my program. I don't want to use library's, only standard C++ functions, and the program should work in Windows 98.

• Which are the most noteable things which make working with Core Date so different than with MySQL?

  - by mystify

  One thing I have in mind is, that datasets in Core Data (or lets say: managed objects) have no ID like known from other databases such as MySQL. Also, they're not in a specific guaranteed order. What else makes Core Data much more "special" compared to working with a relational database like MySQL? Besides the whole object graph persisting and ORM stuff?
