A computer-implemented method for propagating changes to a live website includes logically moving a second immutable delta partition located in a staging database of a staging environment to a production environment. The second immutable delta partition is a replica of a first immutable delta partition located in the staging database of the staging environment. The computer-implemented method further includes logically moving a second delta index located in the staging database to the production environment based on altering the second delta index for the staging database to reference: (i) unique network addresses corresponding to data partitions located in a production database of the production environment and (ii) a unique network address of the second immutable delta partition located in the staging database.

Immutable partitioning for databases

Managing product acquisition based on product characteristics is provided. Characteristics of a product in an electronic shopping cart are determined based on product provider data and product data corresponding to the product. A number of product characteristic points for the product in the electronic shopping cart is calculated based on mapping the determined characteristics of the product to user-defined product points. It is determined whether the calculated number of product characteristic points for the product in the shopping cart is less than or equal to a user-defined product characteristic point budget. In response to determining that the calculated number of product characteristic points for the product in the shopping cart is greater than the user-defined product characteristic point budget, a warning is displayed on a user client device that the user-defined product characteristic point budget is exceeded.
