Inventory system.. Reads and writes

How does one go about building a highly transactional inventory system where
one goes about searching , adding and decrementing inventory..?
Can one share their high level architectural design ?
I am afraid of intensive blocking . When one goes about buying an item from
an inventory, how do you prevent others from not seeing it or even buying it
?
Would really love to hear how this is implemented ?Hassan,
Check the inventory models here:

surrounding that. With everyone hitting the same one or 2 tables, how can i
ensure there is no blocking along with the fact that I can have a 1000 +
users concurrently viewing the inventory while inventory is being
decremented when a customer buys the item and inventory is incremented when
more items are reordered. And make sure no 2 people also book the same 1
item say as an example thats available..
