 ====== atomic redesign ======
+**note:** change point of view into [[reports update]]
 Right now most calculations going with help of module calc which combine data from different tables into one big structure located in memory.

 This we help us to minimize amount of cpu spent to calculate reports and get the database less confuse.
+We will work under database structure with implementation of the functions and do corrections of data step-by-step until the end of redesign.
 Ok, now we may review each screen where we edit data about each movie to see how the atomic concept will work so
+===== what this concept should bring us =====
+ok, the concept should help us to get next things
+  *fix invoice feature
+  *modified exchange rates
+  *good user's logging
+  *avoid bugs and crazy situations
+  *get the engine better and stable
+===== table atomic structure =====
+Goal: have one table for all data coming for the film with three keys (wh, films_id, cinemas_id).
+The data in the table may be repeated, this way don't get us a lot of data but may help to decrease amount of  joins between tables to get work faster. Such approach in use in non-sql databases like moodle. Also duplicate of exchange rate for example, or use gbo as nbo+tax may decrease amount of bugs.
+|field   |Type  |Description  |
+|id  | int  | primary key |
+|wh  |date  |the date of the record  |
+|films_id   |int   |films id   |
+|cinemas_id   |int   |cinemas id   |
+|users_id   |int   |the id of the user who entered this record  |
+|box_1st_day   |int(null)  |box offices 1st atomic record (to bind atomic records into long sequence)  |
+|gbo  |float  |GBO  |
+|nbo  |float  |NBO  |
+|tax  |float  |TAX  |
+|attd  |int  |attendance  |
+|tpfs_id  |int  |format of video (from box office record)   |
+|screen_amount   |int   |amount of screens (from box office record, or 0)  |
+|used_exchrate  |float  |the exchange rate used for this record (applied automatically)  |
+|record_type  |int  |the type of the record: 1 -- box office, 2 -- flat, 3 -- premier, etc   |
+|fixed_id   |int(null)  |optional parameter used for fixed invoice feature -- fix of the entered data in future  |
+possible issue here if the film may be running in several formats (tpfs_id). As I see in current FDM this managed by different names of the same cinema, like "Limegrove" and "Limegrove 3d". But in box offices we always had only one theather format of movie. So I may say about this is not an issue for now.
 ===== Box office form =====
+contains 7 atomic days; each day can be edited while the form is not locked; **note** though the days prior day current may be locked for correct everyday dgbos data;
-===== Flat sale office form =====
+all days will be locked after whole form clicked as locked
+we may use new table bo_records, where first_atomic is first day when the sequence is started, and then the flag whether the form is locked or not.
+===== Flat sale form =====
+enough simple: one atomic day when the sale is happened
 ===== Premier form =====
+also simple: one day being added and locked at once
 ===== Terms form =====
+terms applied to all atomic data used anywhere so no changes both in logic and data
 ===== Exchange rates =====
+Exchange rates applied for the atomic day at the moment when it's entered.
+so here we may have a rule: never change old exchange rate; maybe change the table to use exchange rate for every day, not month as today
