Tmp Project Collection
The Critical Care and Medicine Database has a flexible method of quickly adding additional values required for temporary projects.
For a list of projects we have collected and their collection instructions, see Category:Project.
Storage as attribute-value groups
Adding an actual new field to our database is not trivial, so in to get maximum flexibility our temporary project data is stored in attribute-value groups rather than in new fields for each project. The L TmpV2 table stores the data.
- L TmpV2.project stores the project (or attribute name); there is no tight convention; but a lot of projects only need one entry but some need more, and for those two similarly named project entries will be used.
- L TmpV2.item contains the value for that project
- there are also a boolean, integer, real and notes field in each record of L TmpV2 that can be used to store additional data
The project and item fields are limited to entries in S tmp table, which are supplied in a drop-down.
