database design - How strict should I be with creating a separate association table? -


Say I have a table with a report_type column and I only have 2 reports Is it worth it to create a report_types table for them, and then it refers to this table with a foreign key? Or is it acceptable to store report type as a string in that column?

Things to consider: / P>

  • Can the type add?
  • Do you have the possibility of other tables which refer to report types (such as for collecting statistics or auditing)?
  • Are you likely to use these values ​​in other contexts (like GUI drop-down widgets)?
  • Do you need to associate the additional data (such as the long description) with the report type?

I know that it takes a little bit like overwork to create a table, just to hold two rows and very clearly the gods will support you if you have a column And decide to stay with the check barrier. But if you already have a bunch of code lookup tables to implement restricted sets of values, then there is also a value in stability, well.

Eclipse CDT variable colors in editor -

I know how the editor changes colors for some things But is there a way to do that all the variables are different colors?

Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
