Dim trafferth ynghylch yr olion-troed ecolegol, ond cefais drafferth deall "normalise", yn arbennig gan fy mod i 'n clywed y gair yn bennaf mewn cysylltiad â normaleiddio dwyieithrwydd ayb. Cefais hyn gan gynrychiolydd y cwsmer: "Normalisation Again, I find this very confusing. It means reducing the total to be a "per unit" measure, e.g. per person, per square metre, which can then be used as an basis for future measurements, or for comparisons with other footprint studies. "Standardise" is not quite right. We might invent "unitise" but that won't help. I will have to ponder this question further." Ar y we cefais: In relational database design, the process of Normalisation is organising table data to minimise duplication. "Normalisation involves dividing a database into 2 or more tables and defining relationships between the tables. The objective of normalisation is to isolate data so that additions, deletions and modifications of data fields can be made in just one table and then propagated (spread) through the rest of the database using pre-defined relationships" Callach? Gwelaf fod cyfieithaid yn yr un maes ar y we yn defnyddio "normaleiddio". Ydy hyn yn ddigon da? Ydy rhywun wedi defnyddio rhywbeth arall? Llawer o ddiolch, Ann
