BPM tu'ufa'atasiga tu'ufa'atasia

Talofa, Sa ta'ua e Habr!

O la matou kamupani e faʻapitoa i le atinaʻeina o fofo faʻapitoa a le ERP-vasega, o le leona o loʻo nofoia e faiga faʻapisinisi ma se aofaʻiga tele o pisinisi faʻatatau ma faʻasalalauga pepa a la EDMS. O fa'aliliuga o lo'o i ai nei oa matou oloa e fa'avae i luga o tekinolosi JavaEE, ae o lo'o matou fa'ata'ita'i malosi fo'i i microservices. O se tasi o itu sili ona fa'afitauli o ia fofo o le tu'ufa'atasia lea o subsystems 'ese'ese o lo'o i totonu o pitonu'u lata ane. O faʻafitauli tuʻufaʻatasia e masani lava ona tatou maua ai le tiga tele, e tusa lava po o le a le fausaga o sitaili, tekinolosi faʻapipiʻi ma faʻavae tatou te faʻaogaina, ae talu ai nei na i ai le alualu i luma i le foia o ia faʻafitauli.

I le tusiga ou te aumaia i lou mafaufau, o le a ou talanoa e uiga i le poto masani ma suʻesuʻega fausaga o loʻo i ai i le NPO "Krista" i le nofoaga atofaina. O le a tatou vaʻavaʻai foʻi i se faʻataʻitaʻiga o se fofo faigofie i se faʻafitauli tuʻufaʻatasia mai le manatu o se tagata faʻapipiʻi talosaga ma saili mea o loʻo natia i tua o lenei faigofie.

Fa'ailoga

O faʻataʻitaʻiga faʻataʻitaʻiga ma faʻamatalaga faʻapitoa o loʻo faʻamatalaina i totonu o le tusiga o loʻo tuʻuina mai e aʻu e faʻavae i luga o le poto masani a le tagata lava ia i le tulaga o galuega faʻapitoa. O nei fofo e le fai mai e lautele ma atonu e le sili ona lelei i lalo o isi tulaga o le faʻaaogaina.

O le a le mea e fai i ai le BPM?

Ina ia taliina lenei fesili, e tatau ona tatou suʻesuʻe loloto teisi i faʻamatalaga patino o faʻafitauli faʻaaogaina oa tatou fofo. O le vaega autu o le pisinisi faʻatatau i la tatou faiga masani fefaʻatauaʻiga o loʻo tuʻuina atu faʻamatalaga i totonu o faʻamaumauga e ala i fesoʻotaʻiga faʻaoga, tusi lesona ma faʻamaonia otometi o lenei faʻamaumauga, faʻatinoina e ala i nisi o galuega, lolomiina i se isi faiga / faʻamaumauga faʻamaumauga / faʻamaumauga, fatuina lipoti . O le mea lea, o le galuega autu a le faiga mo tagata faʻatau o le faʻaogaina o latou faiga pisinisi i totonu.

Mo le faʻafaigofie, matou te faʻaogaina le faaupuga "pepa" i fesoʻotaʻiga e pei o se faʻamatalaga o se seti o faʻamaumauga tuʻufaʻatasia e se ki masani e mafai ai ona "sootai" se faʻasologa o galuega.
Ae fa'afefea le manatu fa'atasi? A uma mea uma, o le tuʻufaʻatasiga galuega e faʻatupuina e le fausaga o le faiga, lea e "tipi" i ni vaega E LEʻI i luga o le talosaga a le tagata faʻatau, ae i lalo o le faatosinaga a mea eseese:

• i lalo o le tulafono a Conway;
• o se taunuuga o le toe faʻaaogaina o subsystems na fausia muamua mo isi oloa;
• i le faitalia a le tufuga, e fa'atatau i mana'oga e le fa'atinoina.

O loʻo i ai se faʻaosoosoga tele e vavae ese le faʻaogaina o manatu mai le pisinisi pisinisi o le galuega autu, ina ia aua neʻi faʻaleagaina le faʻaogaina o pisinisi faʻatasi ai ma mea faʻapipiʻi tuʻufaʻatasia ma faʻamalolo ai le tagata faʻapipiʻi talosaga mai le manaʻoga e suʻesuʻe i faʻamatalaga patino o le fausaga fausaga o le faiga. O lenei faiga e iai le tele o mea lelei, ae o le faʻataʻitaʻiga e faʻaalia ai lona le aoga:

• foia faʻafitauli tuʻufaʻatasia e masani lava ona toe foʻi i tua i filifiliga sili ona faigofie i le tulaga o fesoʻotaʻiga fesoʻotaʻiga ona o le faʻatapulaʻaina o vaega faʻalauteleina i le faʻatinoga o le galuega autu (o le le lelei o le tuʻufaʻatasiga faʻatasi o loʻo talanoaina i lalo);
• tu'ufa'atasiga tu'ufa'atasiga o lo'o a'afia pea i manatu autu pisinisi pe a mana'omia ni fa'amatalaga mai se isi faiga fa'avae;
• e le amana'ia e le tagata fa'apipi'i talosaga le tu'ufa'atasiga ma e faigofie ona motusia e ala i le suia o le galuega;
• o le faiga e le toe avea ma se tasi atoa mai le manatu o le tagata e faaaogāina, "suiga" i le va o subsystems e avea ma iloa, ma le toe faia o tagata faaaoga e aliali mai, amataina le fesiitaiga o faamatalaga mai le tasi subsystem i le isi.

O le isi auala o le mafaufau lea i fegalegaleaiga tuʻufaʻatasia o se vaega taua o le manatu autu pisinisi ma le faʻaogaina o galuega. Ina ia taofia le fa'atupuina o tusi pasi mai le si'itia, o le fa'atupuina o feso'ota'iga tu'ufa'atasiga fou e tatau ona faigofie ma leai se taumafaiga, ma sina avanoa e filifili ai se fofo. E sili atu le faigata ona fai nai lo le mea e foliga mai: o le meafaigaluega e tatau ona lava le malosi e tuʻuina atu ai i le tagata faʻaoga le manaʻomia o filifiliga eseese mo lona faʻaaogaina, e aunoa ma le faʻatagaina o ia e "fanaina o ia i le vae." E tele fesili e tatau ona taliina e se inisinia i le tulaga o galuega tuʻufaʻatasia, ae e le tatau ona mafaufau i ai se tagata faʻapipiʻi talosaga i ana galuega i aso taʻitasi: tuaoi o fefaʻatauaiga, tutusa, atomicity, saogalemu, scaling, uta ma le tufatufaina o punaoa, taʻavale, faʻatautaia, tufatufaina ma fesuia'i tulaga, ma isi. E tatau ona ofoina atu i le au atina'e talosaga ni fa'ata'ita'iga faigofie o fofo lea ua natia ai tali i ia fesili uma. O nei faʻataʻitaʻiga e tatau ona matua saogalemu: suiga faʻapisinisi e masani ona suia, lea e faʻateleina ai le lamatiaga o le faʻaalia o mea sese, o le tau o mea sese e tatau ona tumau i se tulaga maualalo.

Ae o le a le mea e fai i ai le BPM? E tele avanoa mo le fa'atinoina o galuega...
O le mea moni, o le isi faʻatinoga o faiga faʻapisinisi e sili ona lauiloa i a tatou fofo - e ala i le faʻamatalaga faʻamatalaga o se faʻataʻitaʻiga suiga o le setete ma le fesoʻotaʻiga o tagata faʻatautaia ma faʻamatalaga pisinisi mo suiga. I lenei tulaga, o le setete e fuafuaina le tulaga o loʻo i ai nei o le "pepa" i le pisinisi pisinisi o se uiga o le "pepa" lava ia.

O le mea lea e foliga mai o le faagasologa i le amataga o se poloketi

O le taʻutaʻua o lenei faʻatinoga e mafua ona o le faigofie ma le saoasaoa o le fatuina o faiga pisinisi laina. Peita'i, a'o fa'aauau pea ona lavelave faiga fa'akomepiuta, o le vaega otometi o le fa'agasologa o pisinisi e fa'atupula'ia ma fa'alavelave. O loʻo manaʻomia le faʻaleagaina, toe faʻaaogaina o vaega o faʻagasologa, faʻapea foʻi ma faʻagasologa faʻasolosolo ina ia faʻatinoina lala taʻitasi i le tutusa. I lalo o ia tulaga, o le meafaigaluega e le faigofie, ma o le faʻasologa o suiga o le setete e leiloa ana faʻamatalaga faʻamatalaga (o fegalegaleaiga faʻatasi e le o atagia i le ata).

E fa'apea le fa'agasologa o le fa'agasologa pe a mae'a le tele o fa'amatalaga o mana'oga fa'amalamalamaga.

O le auala e alu ese ai mai lenei tulaga o le tuufaatasia o le afi jBPM i nisi o oloa e sili ona lavelave faiga pisinisi. I se taimi puʻupuʻu, o lenei fofo na i ai se manuia: na mafai ai ona faʻatinoina faiga faʻalavelave faʻapisinisi aʻo tausia se faʻamatalaga talafeagai ma talafeagai i le faʻamatalaga BPMN2.

O se vaega itiiti o se faiga pisinisi lavelave

I se taimi umi, o le fofo e leʻi ola e tusa ai ma faʻamoemoega: o le maualuga o le galue malosi o le fatuina o pisinisi faʻagasologa e ala i meafaigaluega vaʻaia e leʻi faʻatagaina ai le ausiaina o faʻamaoniga o le gaosiga o oloa, ma o le meafaigaluega lava ia na avea ma se tasi o mea e sili ona le fiafia i ai le au atinaʻe. Sa i ai foi faitioga e uiga i le fausaga o totonu o le afi, lea na mafua ai ona foliga mai o le tele o "patches" ma "tootoo".

O le itu lelei autu o le faʻaaogaina o le jBPM o le faʻalauiloaina lea o faʻamanuiaga ma faʻaleagaina o le i ai o se faiga pisinisi faʻataʻitaʻiga o lona lava tulaga tumau. Na matou vaʻaia foʻi le avanoa e faʻaogaina ai se faiga faʻagasologa e faʻatino ai faʻasalalauga tuʻufaʻatasia lavelave i le va o talosaga eseese e faʻaaoga ai fegalegaleaiga asynchronous e ala i faʻailoga ma feʻau. O le iai o se tulaga tumau e iai sona sao taua i lenei mea.

Faʻavae i luga, e mafai ona tatou faʻauʻuina: O le faʻagasologa o le faiga o le BPM e mafai ai ona tatou foia le tele o galuega e faʻaaogaina ai le faʻatupulaia o pisinisi faʻalavelave, faʻafetaui lelei gaioiga tuʻufaʻatasia i nei faiga ma faʻatumauina le mafai ona faʻaalia le faʻatinoina o le faagasologa i se faʻamatalaga talafeagai.

Le lelei o telefoni faʻatasi e avea o se mamanu tuʻufaʻatasia

Fa'atasi fa'atasi e fa'atatau i le vala'au poloka sili ona faigofie. E tasi le subsystem e galue o le itu o le server ma faʻaalia le API i le auala manaʻomia. O le isi subsystem e galue o le itu o le kalani ma i le taimi sa'o e fai ai se telefoni ma fa'atali mo le i'uga. Fa'alagolago i le fa'atulagaina o faiga, o le kalani ma le 'au'aunaga e mafai ona maua i totonu o le fa'aoga tutusa ma le fa'agasologa, po'o le eseese. I le tulaga lona lua, e tatau ona e faʻaaogaina nisi o faʻatinoga RPC ma tuʻuina atu le faʻavasegaina o tapulaʻa ma le iʻuga o le valaau.

O lenei faʻataʻitaʻiga tuʻufaʻatasia o loʻo i ai se seti tele o mea le lelei, ae o loʻo faʻaaogaina lautele i le faʻatinoga ona o lona faigofie. O le saoasaoa o le faʻatinoga e faʻafeiloaʻi ma faʻamalosia oe e faʻaaogaina pea lava pea i le feagai ai ma taimi faigata, faʻamaumau le fofo e pei o aitalafu faʻapitoa. Ae e tupu foʻi e faʻaaogaina e le au atinaʻe e leai se poto masani, naʻo le le iloa o aʻafiaga leaga.

I le faʻaopoopoga i le faʻateleina o le faʻateleina o fesoʻotaʻiga i lalo o le system, o loʻo i ai foi faʻafitauli faʻapitoa i le "tuputupu" ma le "faʻalauteleina" fefaʻatauaiga. O le mea moni, afai e faia e le pisinisi pisinisi ni suiga, ona le mafai lea ona aloese mai fefaʻatauaiga, ma o fefaʻatauaiga, i le isi itu, poloka nisi punaoa talosaga e aʻafia i nei suiga. O lona uiga, se'ia o'o ina fa'atali le isi subsystem mo se tali mai le isi, o le a le mafai ona fa'amae'aina le fefa'atauaiga ma aveese loka. O lenei mea e matua faʻateleina ai le lamatiaga o aʻafiaga eseese:

• Ua leiloa le tali atu o le faiga, o tagata e faʻatali mo se taimi umi mo tali i fesili;
• e masani lava ona taofia e le server le tali atu i talosaga a tagata ona o le tumu o filo filo: o le tele o filo o loʻo lokaina i luga o se punaoa o loʻo nofoia e se fefaʻatauaiga;
• Ua amata ona aliali mai faʻalavelave faʻafuaseʻi: o le ono tupu mai e faʻalagolago lava i le umi o fefaʻatauaiga, le aofaʻi o pisinisi faʻatau ma loka o loʻo aʻafia i le fefaʻatauaiga;
• e aliali mai ni mea sese i le taimi o fefa'atauaiga;
• le 'auʻaunaga "faʻaletonu" ma OutOfMemory pe afai e manaʻomia e le galuega le faʻaogaina ma le suia o le tele o faʻamaumauga, ma o le i ai o faʻatasi faʻatasi e faigata tele ona vaeluaina le gaioiga i fefaʻatauaiga "mama".

Mai se vaaiga faufale, o le faʻaogaina o le polokaina o telefoni i le taimi o le tuʻufaʻatasia e oʻo atu ai i le leiloa o le puleaina o le lelei o subsystems taʻitasi: e le mafai ona faʻamautinoa le faʻamoemoeina o le lelei o le tasi subsystem i le vavae ese mai faʻailoga lelei o le isi subsystem. Afai o subsystems e atiaʻe e 'au eseese, o se faʻafitauli tele lea.

E sili atu le manaia o mea pe a fai o loʻo tuʻufaʻatasia vaega laiti o loʻo i totonu o talosaga eseese ma e manaʻomia le faia o suiga faʻatasi i itu uma e lua. E faʻapefea ona faʻamautinoa le faʻatauga o nei suiga?

Afai e faia suiga i fefaʻatauaʻiga eseese, ona e manaʻomia lea e tuʻuina atu faʻamaonia tuusaunoaga taulimaina ma taui, ma o lenei mea e faʻaumatia atoa ai le aoga autu o tuʻufaʻatasiga faʻatasi - faigofie.

O fefaʻatauaiga faʻasalalau e oʻo mai foi i le mafaufau, ae matou te le faʻaaogaina ia matou fofo: e faigata ona faʻamautinoa le faʻamaoni.

"Saga" o se fofo i le faʻafitauli tau fefaʻatauaiga

Faatasi ai ma le faatupulaia o le lauiloa o microservices, o le manaoga mo Mamanu Saga.

O lenei mamanu e foia atoatoa ai faafitauli o loʻo taʻua i luga o fefaʻatauaiga umi, ma faʻalauteleina ai le gafatia o le puleaina o le tulaga o le faiga mai le itu o le pisinisi faʻatauvaʻa: taui pe a maeʻa se fefaʻatauaiga ua le mafai ona toe faʻafoʻi le faiga i lona tulaga muamua, ae tuʻuina atu. se isi auala e fa'agasolo ai fa'amaumauga. Ole mea lea e mafai ai ona e aloese mai le toe faia ma le manuia faʻamaeʻaina faʻasologa o faʻamaumauga pe a taumafai e aumai le faagasologa i se faʻaiʻuga "lelei".

O le mea e malie ai, i faiga monolithic e talafeagai foi lenei mamanu pe a oʻo mai i le tuʻufaʻatasia o vaega laiti faʻatasi ma aʻafiaga leaga e mafua mai i fefaʻatauaiga umi ma loka punaoa talafeagai e matauina.

E tusa ai ma a tatou faiga pisinisi i le BPM style, e foliga mai e matua faigofie lava le faʻatinoina o le "Sagas": o laasaga taʻitasi o le "Saga" e mafai ona faʻamaonia o ni gaioiga i totonu o le pisinisi, ma le tulaga faifaipea o le pisinisi pisinisi foi. fuafua le tulaga totonu o le "Saga". O lona uiga, matou te le mana'omia so'o se faiga fa'aopoopo fa'aopoopo. Pau lava le mea e te manaʻomia o se fefaʻatauaʻiga feʻau e lagolagoina "ia le itiiti ifo ma le tasi" faʻamaoniga o se felauaiga.

Ae o lenei fofo e iai foi lona lava "tau":

• ua sili atu ona lavelave le manatu faapisinisi: e manaʻomia ona fai se taui;
• e tatau ona lafoaʻia le faʻamaoni atoatoa, lea e mafai ona sili ona maaleale mo faiga monolithic;
• Ua fai si lavelave teisi le fausaga, ma ua aliali mai ai se mana'oga faaopoopo mo se faife'au fe'au;
• o le a manaʻomia ni mea faigaluega faʻapitoa e mataʻituina ma pulega (e ui o le tulaga lautele e lelei lenei: o le a faʻateleina le lelei o le auaunaga faʻapitoa).

Mo faiga monolithic, o le faʻamaoniga mo le faʻaaogaina o le "Sag" e le o manino. Mo microservices ma isi SOA, lea e foliga mai o loʻo i ai se tagata faʻatau oloa, ma o loʻo tuʻufaʻatasia atoatoa i le amataga o le poloketi, o faʻamanuiaga o le faʻaaogaina o lenei mamanu e mafai ona sili atu nai lo le le lelei, aemaise lava pe afai o loʻo i ai se API talafeagai i le pisinisi pisinisi. tulaga.

Encapsulating manatu pisinisi i microservices

Ina ua amata ona matou faʻataʻitaʻiina i microservices, na tulaʻi mai se fesili talafeagai: o fea e tuʻu ai le faʻaogaina o pisinisi pisinisi e fesoʻotaʻi ma le auaunaga e faʻamautinoa ai le faʻaauau pea o faʻamaumauga a le domain?

Pe a vaʻavaʻai i le fausaga o BPMS eseese, atonu e foliga mai e talafeagai le tuʻufaʻatasia o pisinisi faʻatauvaʻa mai le faʻaauau: fatuina se faʻavae o faʻavae ma vaega-tutoʻatasi microservices e fausia ai se siosiomaga ma pusa mo le faʻatinoina o faʻamatalaga pisinisi, ma mamanuina le faʻaauauina o faʻamatalaga faʻamaumauga e pei o. se isi vaega o auaunaga laiti faigofie ma mama. Fa'agasologa o pisinisi i lenei tulaga e fa'atino ai le fa'atulagaina o au'aunaga o le fa'aputuga tumau.

O lenei faiga e i ai se aoga tele: e mafai ona e faʻateleina le faʻatinoga o le faʻavae i le tele e te manaʻo ai, ma naʻo le vaega tutusa o microservices platform o le a avea ma "gaʻo" mai lenei mea. O faiga fa'apisinisi mai so'o se vaega e vave ona mafai ona fa'aogaina le galuega fou o le fa'avae i le taimi lava e fa'afou ai.

O se suʻesuʻega faʻapitoa na faʻaalia ai le le lelei tele o lenei auala:

• o se auaunaga fa'avae e fa'atino ai le fa'atatauga fa'apisinisi o le tele o fa'alapotopotoga i le taimi e tasi o lo'o i ai ni fa'alavelave tetele e pei o se tasi o le fa'aletonu. O suiga faifaipea i mafaufauga faapisinisi e faateleina ai le tulaga lamatia o mea sese e mafua ai le faaletonu o le polokalama;
• fa'afitauli fa'atinoga: fa'atatau pisinisi e galue ma ana fa'amaumauga e ala i se va'aiga vaapiapi ma fa'agesegese:
  • o faʻamatalaga o le a toe faʻapipiʻiina ma pamu i totonu o le upega o fesoʻotaʻiga;
  • o le a masani ona tu'uina atu e se 'au'aunaga fa'apitoa le tele o fa'amatalaga nai lo le mea e mana'omia mo le fa'aogaina o pisinisi ona o le le lava o le gafatia mo le fa'avasegaina o talosaga ile tulaga ole API i fafo ole auaunaga;
  • le tele o vaega tuto'atasi o pisinisi fa'atatau e mafai ona toe talosagaina fa'amatalaga tutusa mo le fa'agaioiga (o lenei fa'afitauli e mafai ona fa'aitiitia e ala i le fa'aopoopoina o vaega o le sauniga e fa'apipi'i ai fa'amaumauga, ae o lenei mea e atili fa'alavelaveina ai le fausaga ma fa'atupuina ai fa'afitauli o fa'amatalaga talafeagai ma le fa'aleaogaina o le cache);
• fa'afitauli tau fefa'atauaiga:
  • faiga pisinisi ma tulaga faifai pea, lea e teuina e se auaunaga tulaga, e le ogatasi ma faʻamaumauga faʻamaumauga, ma e leai ni auala faigofie e foia ai lenei faʻafitauli;
  • tu'uina le poloka o fa'amaumauga i fafo atu o le fefa'ataua'iga: afai e mana'omia e le pisinisi fa'atauva'a ona faia ni suiga pe a uma ona siaki muamua le sa'o o fa'amaumauga o lo'o i ai nei, e tatau ona fa'ate'aina le avanoa o se suiga fa'atauva i fa'amaumauga fa'agasolo. O le polokaina o faʻamatalaga mai fafo e mafai ona fesoasoani e foia le faʻafitauli, ae o sea fofo e maua ai faʻalavelave faʻaopoopo ma faʻaitiitia ai le faʻalagolago atoa o le faiga;
• faʻafitauli faʻaopoopo pe a faʻafouina: i nisi tulaga, o le auaunaga faʻaauau ma le faʻatatau pisinisi e manaʻomia ona faʻafouina faʻatasi poʻo se faʻasologa saʻo.

Mulimuli ane, e tatau ona matou toe foʻi i faʻavae: faʻapipiʻi faʻamaumauga faʻamaumauga ma faʻamatalaga pisinisi pisinisi i totonu o le tasi microservice. O lenei faiga e faʻafaigofie ai le manatu o se microservice o se vaega taua o le faiga ma e le faʻaalia ai faʻafitauli o loʻo i luga. E le maua fua foi lenei mea:

• E mana'omia le fa'avasegaina o le API mo le fegalegaleai ma manatu fa'apisinisi (aemaise lava, e tu'uina atu ai galuega fa'aoga o se vaega o faiga fa'apisinisi) ma auaunaga fa'avae API; e manaʻomia le faʻaeteete atili i suiga API, fesoʻotaʻiga i luma ma tua;
• e mana'omia le fa'aopoopoina o faletusi ta'avale fa'aopoopo e fa'amautinoa ai le fa'agaioiina o pisinisi fa'atatau o se vaega o ia auaunaga laiti ta'itasi, ma o lea e tula'i mai ai mana'oga fou mo ia faletusi: mama ma le la'ititi o fa'alagolagoga fa'asolo;
• e mana'omia e le au atina'e fa'atauva'a pisinisi ona mata'ituina fa'aliliuga a le faletusi: afai e le'i fa'amae'aina se microservice mo se taimi umi, e foliga mai o le a iai se fa'amatalaga tuai o faletusi. E mafai ona avea lenei mea ma fa'alavelave fa'afuase'i i le fa'aopoopoina o se vaega fou ma e ono mana'omia ai le si'itia o le manatu fa'apisinisi tuai o lea auaunaga i fa'aliliuga fou o faletusi pe a iai ni suiga le fetaui i le va o fa'aliliuga.

O loʻo iai foʻi se vaega o auaunaga faʻavae i totonu o sea fausaga, ae o lenei laulau e le o toe fausia ai se atigipusa mo le faʻatinoina o pisinisi pisinisi, ae naʻo lona siosiomaga, e tuʻuina atu ai galuega fesoasoani "platform". E mana'omia se fa'apena e le gata ina ia fa'atumauina ai le mama mama ole vaega ole microservices, ae fa'apea fo'i ile fa'atotonugalemu o le pulega.

Mo se faʻataʻitaʻiga, o gaioiga a tagata faʻaoga i faiga faʻapisinisi e maua ai galuega. Ae peitaʻi, pe a galue i galuega, e tatau i le tagata faʻaoga ona vaʻai i galuega mai vaega uma i le lisi lautele, o lona uiga e tatau ona i ai se auaunaga faʻamautu galuega faʻatulagaina, faʻamalo mai le faʻaogaina o pisinisi pisinisi. O le fa'atumauina o le fa'avasegaina o manatu fa'apisinisi i se tulaga fa'apea e fai si fa'afitauli, ma o le isi lea fetuutuuna'iga o lenei fausaga.

Tu'ufa'atasiga o faiga fa'apisinisi e ala i mata o se tagata fa'apipi'i talosaga

E pei ona taʻua i luga, e tatau ona aveese le tagata e faia talosaga mai le tulaga faʻainisinia ma faʻainisinia o le faʻatinoina o fegalegaleaiga o le tele o talosaga ina ia mafai ai e se tasi ona faʻamoemoe i le gaosiga lelei o atinaʻe.

Sei o tatou taumafai e foia se faʻafitauli faigata tuʻufaʻatasia, faʻapitoa faʻapitoa mo le tusiga. Ole a avea lea ma se "taaloga" galuega e aofia ai ni talosaga se tolu, lea e faʻamatalaina ai e latou taʻitasi se igoa faʻapitoa: "app1", "app2", "app3".

I totonu o talosaga taʻitasi, o loʻo faʻalauiloaina pisinisi e amata ona "taʻalo polo" e ala i le pasi tuʻufaʻatasia. O fe'au e iai le igoa "Polo" o le a avea ma polo.

Tulafono o le taaloga:

• o le tagata taalo muamua o le amataga. Na te valaaulia isi tagata taaalo i le taaloga, amata le taaloga ma mafai ona faamutaina i soo se taimi;
• o isi tagata taaalo latou te tautino atu lo latou auai i le taaloga, "ia iloa" e le tasi le isi ma le tagata taalo muamua;
• a uma ona maua le polo, ona filifili lea e le tagata taalo se isi tagata taalo e auai ma pasi atu le polo ia te ia. Le aofa'i o fa'asalalauga e faitaulia;
• E tofu tagata ta'alo ma "malosi" e fa'aitiitia i pasi ta'itasi o le polo a le tagata ta'alo. A uma le malosi, ona alu ese lea o le tagata taalo mai le taaloga, ma faailoa atu lona faamavae;
• afai e tuua na o le tagata taalo, e vave lava ona ia faailoa atu lona alu ese;
• A fa'ate'a uma ta'aalo, e ta'u atu e le tagata ta'amua ua uma le ta'aloga. Afai na te tuua vave le taaloga, e tumau pea o ia e mulimuli i le taaloga e faauma ai.

Ina ia foia lenei faʻafitauli, o le a ou faʻaogaina la matou DSL mo pisinisi faʻagasologa, lea e mafai ai ona matou faʻamatalaina le faʻaogaina i Kotlin faʻatasi, faʻatasi ai ma le laʻititi o le boilerplate.

O le pisinisi pisinisi a le tagata taalo muamua (aka le amataga o le taaloga) o le a galue i le app1 talosaga:

Faʻamautinoaina le saogalemu o filo o faʻamatalaga pisinisi

Ole fa'ata'ita'iga lava lea ole faiga pisinisi e mafai ona maua ni fe'au ma mea e tutupu i le taimi e tasi, o le faagasologa o le a amata tutusa. I le taimi lava e tasi, mo se tagata faʻapipiʻi talosaga, o mea uma e tatau ona faigofie ma saogalemu-saogalemu.

O le fa'atatauga fa'apisinisi o se fa'agasologa o lo'o fa'agasolo ai fa'alavelave ta'itasi i fafo e a'afia ai le fa'agasologa o pisinisi ta'ito'atasi. O mea faapena e mafai ona:

• fa'alauiloaina o se faiga fa'apisinisi;
• tagata fa'aoga gaioiga e feso'ota'i ma gaioiga i totonu o se fa'agasologa pisinisi;
• mauaina o se fe'au po'o se fa'ailo o lo'o fa'amauina ai se fa'ata'ita'iga fa'apisinisi;
• fa'aosoina o se taimi fa'atulagaina e se fa'ata'ita'iga fa'agaioiga pisinisi;
• fa'atonuga e ala ile API (fa'ata'ita'iga, fa'alavelave fa'agasolo).

O ia mea e tutupu e mafai ona suia ai le tulaga o se faʻataʻitaʻiga pisinisi faʻataʻitaʻiga: o nisi gaioiga e mafai ona muta ae o isi e mafai ona amata, ma e ono suia le tau o meatotino tumau. O le tapunia o so'o se gaioiga e mafai ona fa'agaoioia ai se tasi pe sili atu o gaioiga nei. O i latou, i le isi itu, e mafai ona taofi le faʻatali mo isi mea tutupu pe, afai latou te le manaʻomia ni faʻamatalaga faaopoopo, e mafai ona faʻamaeʻaina i le fefaʻatauaiga tutusa. Aʻo leʻi tapunia le fefaʻatauaʻiga, o le tulaga fou o le pisinisi pisinisi o loʻo faʻasaoina i totonu o faʻamaumauga, lea o le a faʻatali mo le isi mea i fafo e tupu.

I a matou faʻataʻitaʻiga, o le InitialPlayer pisinisi faʻagasologa o loʻo i ai se taʻutinoga

uniqueConstraint = UniqueConstraints.singleton

O le mea lea, o le ogalaau o loʻo i ai feʻau e uiga i le aveina ma le tatalaina o le loka o le ki fetaui. E leai ni fe'au fa'apea mo isi faiga pisinisi: uniqueConstraint e le'i setiina.

Faʻafitauli o faiga faʻapisinisi ma le tulaga faifai pea

O nisi taimi o le i ai o se tulaga tumau e le gata e fesoasoani, ae e matua faʻalavelave foi i le atinaʻe.
E amata fa'afitauli pe a mana'omia ona fai ni suiga ile fa'atatau o pisinisi ma/po'o le fa'ata'ita'iga o faiga fa'apisinisi. E le o tutusa uma ia suiga ma le tulaga tuai o faiga pisinisi. Afai e tele taimi ola i totonu o faʻamaumauga, ona faia lea o suiga le fetaui e mafai ona mafua ai le tele o faʻalavelave, lea e masani ona matou feagai pe a faʻaaoga le jBPM.

Faʻalagolago i le loloto o suiga, e mafai ona e galue i ni auala se lua:

1. fatuina se ituaiga faiga pisinisi fou ina ia aua nei faia ni suiga le fetaui i le mea tuai, ma faʻaaoga nai lo le mea tuai pe a faʻalauiloa mea fou. O kopi tuai o le a faaauau pea ona galue "pei o le taimi muamua";
2. femalaga'i le tulaga faifai pea o faiga fa'apisinisi pe a fa'afou le fa'atatau o pisinisi.

O le auala muamua e faigofie, ae o loʻo i ai ona tapulaʻa ma faʻaletonu, mo se faʻataʻitaʻiga:

• fa'aluaina o fa'atauga fa'apisinisi i le tele o fa'ata'ita'iga fa'agasologa o pisinisi, fa'ateleina le tele o fa'atatau pisinisi;
• E masani ona manaʻomia se suiga vave i pisinisi fou (i tulaga o galuega tuʻufaʻatasia - toetoe lava o taimi uma);
• e le iloa e le atinaʻe poʻo le a le taimi e mafai ai ona tapeina faʻataʻitaʻiga tuai.

I le faʻataʻitaʻiga matou te faʻaogaina auala uma e lua, ae ua matou faia ni filifiliga e faʻafaigofie ai o matou olaga:
