I moved the data into Excel where I could manipulate it. Please consider putting “keepers” in a separate column. Why? Because there are two disparate pieces of information in the same column. It is always preferable to have a single data type per column as it avoids complications when sorting or arranging the data. This would also enable you to add other information such as “historical”, “obsolete”, “lost”, “commercial”, etc.
side though: I really need to write a guide on data organization, management, and manipulation. Publications about data “analysis” and “mining” are so outdated now that they are actually slowing down the use and interpretation of results.
Done, although in my perspective it is a collection.
A database is a collection of normalized tables with a common set of keys. I have provided this database in spreadsheet format to ease the import process by others. It is not intended as a consumer end-product.
Please help me understand what you are conveying with “keepers”. To me, it means they are unusually good, perhaps among the best to be grown. I am inferring that you have most or all of them growing. Does this match your meaning?
