In traditional AISs,journals provide a chronological listing of transactions.In a relational database designed according to the REA data model,event entities store information about transactions.Thus,the information normally found in a journal is contained in the tables used to record data about events.For example,each row in the Sales event table contains information about a particular sales transaction.Thus,a sales journal can be produced by writing a query that displays the appropriate entries in the sales table for a given period.In a similar manner,queries of the Order Inventory event and Cash Disbursements event tables can be used to generate purchases and cash disbursements journals.
