sql - Keeping track of total inventory, sales, etc; stored procedure or something like elastic search -


i'm creating inventory management , sales tool e-commerce site. i'm new programming, , i'm curious best way keep track of totals. example company sells 200 products day, , able keep track of total amount of products sold in dollars, units sold, , graph data. able graph month's worth of these numbers (may 14: 145 units sold, $14,545, $2000 profit, may 15: etc). best way of doing this?

i thought creating total's table, , every time new order comes adds order value previous total's amount, seems cloudy quick if order doesn't logged.

doing select , adding total's each day month seems bad performance wise.

what options have , recommend best solution?

i recommend against creating totals table. while building report summarizes totals transactional data may seen cause performance problem, in practice might not bad think. 2 hundred orders per day on thirty days isn't many records modern relational database systems.

if did run significant performance issue 1 report, 1 thing run report during off-hours business may have , cache results of run in table use when wants view report. however, before going trouble recommend trying out mentioned above , see if performance of issue.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
