General Ledgers and T-accounts
A ledger is a document or computer file that shows all business transactions by account. Note that the general ledger, the core of every accounting system, contains all of the same entries as that posted to the general journal—the only difference is that the data are sorted by date in a journal and by account in the ledger. The general ledger is useful for reviewing all of the activity related to a single account. T-accounts, explained in Appendix 23, are representations of ledger accounts and are frequently used to describe or analyze accounting transactions.
