Hi! Why does certain transactions have "(null)" at the end? Is it because there are not entities (customer, vendors, etc) at the end? For invoices for example the we would have the name of the customers at the end in brackets.
Update: I added a screenshot just to show what I mean (i censored parts of the prefix)
NULL is used in computing most often (always?) to signify "not a value." This is different than zero: in a bank database, a zero value means no money, while a NULL value means there has been no value assigned to the balance.
This is a specialized usage, but increasingly common as more people learn to program.
Almost the only time you hear or see null is in the legal expression ‘null and void’, while nil normally indicates that a football team has scored no goals. If the bottom line of your bank statement shows neither a credit nor a debit, what you have is a zero balance.
