Catalogue management is the information about the products and items which the website is keen to offer. The information stored under catalogue management can be a product's cost, dimension, color, and so on, that is meta information of a product. This information, unlike session information, is read centric. But like session data, catalogue data has seen evolution starting with RDBMS systems which were the natural choice back then because of lack of choices to store data. The problem with RDBMS system was that it did not offer performance. Also, the fixed schema centric systems added to the problems since the meta information of products changed with the products themselves. Some products had color, length, breadth, and height whereas some had author, number of pages, and ISBN. Creating schemas to accommodate this requirement was always cumbersome and, at some point or another we have faced this problem.
