Hi Sir, The way you have laid out all the crucial variables in BDS structure makes it easy to understand the basis of creating the dataset and subsequently which variables will be used in displays. This is a great representation instead of staring at the metadata spreadsheet. Thank you. :-)
Glad that you found the explanation useful. When we say 'timepoint', it has a broad definition to cover analysis visit, date, time, timepoint of collection as well. It also includes derived records like LOCF etc. So, we can technically only have 'one record per parameter per timepoint' - not 'one or more'. I do not mean to disagree with you but just conveying my intepretaion of it.
Hi Monika, the generic definition as ADaM IG is 'A BDS dataset contains one or more records per subject, per analysis parameter, per analysis timepoint.' . I meant the same when I said 'one record per parameter per timepoint'. When defining the record structure for a specific dataset in the define.xml, we generally do not use 'or more' part of the IG definition.
Hi Harsh, I will try to create one for ADSL.. but there is no such 'standard' occds variables as they are based on a specific SDTM dataset.. you can watch my videos on SDTM AE an CM concept maps for standard variables in them in th SDTM playlist of this channel

Hi, glad you liked the approach. Thank you.
Very easily & beautifully explained to a totally new SAS User. Keep doing the good work.
Thank you, I will
One or more record, not one record - BDS structure. Very easy way of explanation and very much useful.

Thank you so much for this video. Please keep making more videos if you have time.
Thank you, I will
Wonderful video. Explained very well. Could you please do a similar video for ADam Occurance data structure variables.
Glad you liked it, Nithya. Will create soon.
Sir, Thank you....I am just confused
BDS structure is one or more record per analysis parameters per analysis time point???

it's not mandatory that BDS has only one record per parameter per timepoint, it's only recommended
Agree Rajesh. Thank you.
Hi..Thanks for posting very useful videos..do you provide SAS training?
No Vamshi Krishna, we do not provide training. Glad that you found the videos helpful, thank you.
Sir Can you explain difference between arm and actarm....
Hi, it is covered here in this lesson.
www.mycsg.in/tasks.php?area=TASKS&concept=SDTMGEN&lesson=TASKS_SDTMGEN_L072
Hi mycsg ，can you share some video about recist 1.1 criteria? Thanks!
Will do soon
Hi, please upload videos about different flags of bds structure. thanks in advance😊
Hi Kirtik, I am working on it, will upload soon.
Sir please make video on ADSL and OCCDS variables.
sure, will try to add as soon as possible
Thankyou sir ❤️
sir can you upload adsl and occds variable remember concept map
