ʻO Cognos Mashup Services Boot Camp - Hoʻomaka

Nā mea kākau: hoʻohana i ka leo o ka mea hoʻokani ʻo R. Lee Ermey (Gunny mai Ka Pelekikena Kikelikona)
No nā ʻatikala hou aʻe e aʻo wau iā ʻoe. Kāhea paha ʻoe iaʻu ʻo "Drill Sergeant". E wāwahi wau iā ʻoe i nā mea hana i loko o nā ʻano one haʻahaʻa i hele mai a kūkulu hou iā ʻoe i loko o nā ʻāpana silikone i kālai ʻia. E haʻalele ʻoe i aneʻi me nā pono hana āu e pono ai e ola i ke kahua kaua i kapa ʻia ʻo Cognos Mashup Service. Hiki iā ʻoe ke kuhi i kou ala ma waena o nā ʻāina hiʻohiʻona hiʻohiʻona weliweli. Hiki iā ʻoe ke hoʻokaʻawale i ka hoaaloha mai ka ʻenemi i ka wā e pili ana i nā manaʻo hoʻolālā. Ua noʻonoʻo paha ʻoe e coddled ʻia ʻoe e ka hoʻohiki o nā lawelawe REST maʻalahi. Akā ʻaʻole kēia ka REST o kou mama. Hiki iaʻu ke kiʻi i kahi "YILL DRILL SERGEANT!"? E hāʻule a hāʻawi iaʻu i iwakālua!

ʻĀ, e ʻae ʻoe iaʻu i kahi hoʻomaha mai ke ʻano e hāʻawi pololei iā ʻoe. I kēia pule e nānā ana mākou i nā mea nui o ka Cognos Mashup Service. E wāwahi mākou iā ia i loko o kāna mau ʻāpana e ʻike ai pehea e lawe ai i ka waiwai i ka hoʻohuihui o nā mōhai IBM Cognos.

I mea e hoʻohana ai i ka Cognos Mashup Service pono i kekahi e hoʻokō i nā koi liʻiliʻi loa:
1. IBM Cognos BI Server 8.4.1
2. Hiki i kahi mea kūʻai aku ke launa me SOAP a i ʻole nā ​​URL i hoʻokumu ʻia ma luna o HTTP
Hiki ke kiʻi ʻia ʻo Cognos Connection a me ka Cognos Mashup Service ma o ka puka o Cognos

Hana ʻia ʻo Cognos Mashup Service i ʻelua ʻāpana ʻokoʻa e hana like i mea e ʻae ai nā mea kūʻai i ka ʻikepili i waho o ka mea nānā hōʻike a i nā hiʻohiʻona ʻike. ʻO kahi ʻāpana o ka lawelawe ke ʻano halihali a ʻo ka ʻē aʻe ka ukana. I ke kiʻikuhi ma lalo hiki iā mākou ke noʻonoʻo i ka noi ma ke ʻano he halihali a me ka pane e like me ka ukana.

ʻO ke kikowaena halihali ke ala e hiki ai iā mākou ke noi i nā hōʻike. ʻElua mau koho no nā mea kūʻai aku e hoʻohana ai. Hoʻokumu ʻia kahi kopa kope a hoʻohana ka mea ʻē i nā ʻano URL REST. Holo nā kikowaena ʻelua ma luna o HTTP a ʻano like i ka hanana. ʻO ia, no kēlā me kēia hana loiloi i ka interface style SOAP aia kahi mea like i ke kaila REST. Nānā nā kikoʻī kikoʻī kikoʻī i nā idiosyncrasies no ke ʻano noi komo i koho ʻia. Akā ʻo ka laina lalo… ka hiki ke ʻeʻe, noi i kahi hōʻike, loaʻa ka hopena, a loaʻa i ka hoʻomoana i nā hoʻomoana ʻelua.

No laila e nīnau paha ʻoe iā ʻoe iho "iā ʻoe iho, no ke aha wau e koho ai i kekahi ma mua o kekahi?" Pinepine ka pane i kēia hōʻike iā ia iho ke nānā i ka ʻenehana papahana a i ʻole nā ​​ʻaha kūkā. E lawe i kahi laʻana o kahi mea kūʻai e hoʻomohala ʻia ma ka ʻaoʻao o ka mea kūʻai aku. Hoʻohana ia HTML a me JavaScript e launa pū me ka Cognos Mashup Service. I kahi hawewe ka REST URL ma muli o ka pilina e hana no ka maʻalahi o ka hoʻopili ʻana. I ka hoʻohālikelike ʻana, loaʻa paha i kahi papahana ʻē aʻe nā waiwai Cognos SDK i loko o kahi lawelawe Java. Ua maʻa lākou i nā lāʻau SOAP i hōʻike ʻia e ka SDK. Manaʻo ʻoi aku ka maʻamau no kēia kūlana e hilinaʻi i ka lilo ʻana i mea kūʻai aku SOAP o nā lawelawe mashup. I ka hoʻomaʻamaʻa ʻaʻole kēia he koho paʻakikī e kaupaona. Ke nānā nei i nā koho ʻelua e like me ka mea ʻoi aku ka maikaʻi i ka wā e noʻonoʻo ana i ka hopena holoʻokoʻa. Nā hoʻāʻo e hoʻohana i ka manaʻo ʻē aʻe ua koi ʻia.
ʻO nā hana loiloi i hāʻawi ʻia e ka ʻoihana halihali e ʻae i kahi mea kūʻai e hana i nā hana i kau ʻia ma ka holo ʻana i nā hōʻike a Cognos a me nā kālailai. Hāʻawi ka papa o nā koho i kahi mea kūʻai aku e hele i waena o ke ola holoʻokoʻa o ka holo ʻana i kahi hōʻike. Pākuʻi ʻia kēia:
• hōʻoia
• Hāʻawi i ka paramameter
• Hōʻike Hoike (synchronous a me asynchronous)
• hana drill
• Loaʻa ka loaʻa ʻana
Hāʻawi ka lawelawe mashup i kekahi mau mea maikaʻi i loaʻa ʻole ma o ka SDK. Eia nō naʻe, e mālama mākou i kēlā kūkā kamaʻilio no kahi ʻatikala e hiki mai ana ke hoʻohālikelike a hoʻohālikelike i ka Mashup Service e kūʻē i ka SDK.
I kēia manawa he mea hiki iā mākou ke kāhea i nā hōʻike ma o ka HTTP i hoʻonohonoho ʻia o nā lawelawe. He aha ka mea i puka aʻe i ka hopena ʻē aʻe? Alakaʻi iā mākou i ka ʻāpana ʻelua o ka lawelawe mashup. Kikokiko… ”ʻO ka ukana”.

ʻO kekahi o nā koho i hiki iā mākou ke kikoʻī ke kāhea i kahi hōʻike ma o ka lawelawe mashup ʻo ia ka hōʻano puka. Aia kekahi mau koho i loaʻa e like me HTML Layout Data XML (LDX), a me JSON. Aia kekahi mau mea ʻē aʻe akā uhi kēia i ka pae ma abroad manaʻo. ʻO ka HTML ka mea āu e manaʻo ai. Ua like like lākou me ka mea e loaʻa mai i kahi hōʻike i nānā ʻia ma o ka mea ʻike hōʻike ma loko o Cognos Connection. ʻO nā mana ʻoi aku ka hoʻohiki ʻo LDX a me JSON. I ka ʻoiaʻiʻo inā loaʻa kahi smash maopopo i hoʻokau ʻia e ka Cognos Mashup Service ʻo ia ka hoʻolauna o kēia mau ʻano ʻelua.

Hāʻawi kēia mau ʻano ʻelua i ka hoʻopuka hōʻike i kahi hōʻike kūlike ʻole o ka hōʻike. Hāʻawi kēia i ka mea kūʻai i ka hoʻopuka hōʻike e hāʻawi i ka ʻike i kēlā me kēia hiʻohiʻona e hiki ke hoʻomaopopo iā JSON a i ʻole XML. E hoʻolōʻihi i ka manawa e heluhelu hou i kēlā.

Hoʻokuʻu ʻia ka ʻikepili hōʻike i nā kaulahao i kau ʻia ma luna e Cognos Viewer. Hiki i kēia ʻikepili ke holoholo i nā wahi kūpono ʻole ma mua. ʻO kahi laʻana, hiki i nā Pūnaewele Pūnaewele Rich ke hoʻohana i nā papahana e like me ka Google Visualization API a i ʻole Ext-JS e ʻala ai i ka hōʻike o ka ʻike. Lilo i ka hoʻohui pūnaewele i mea ʻoi aku ka hiki ke hoʻopili ʻia ka hopena i kēia mau hāmeʻa. Hiki ke hoʻoulu maoli ʻia nā ʻike Cognos me ka ʻikepili mai nā kumuwaiwai o waho. I ka ʻoiaʻiʻo, ua ʻike ʻia nā ʻikepili mai Cognos BI i kēia manawa, i ka nāhelehele, me ka hoʻopili ʻana me ka ʻikepili mai kahi ʻōnaehana hoʻokele ʻike i makemake ʻia ma ka pūnaewele Ext-JS like ʻole. Scandusive! He aha ka manaʻo o kēia? I kēia hihia, ʻae ʻia e mālama ʻia nā ʻikepili ʻelua ma o kā lākou mau pono ponoʻī me ka ʻole o kahi kaʻina hana paʻakikī e hoʻohui iā lākou ma ka polokalamu kele pūnaewele.
Ma lalo iho kahi haʻahaʻa haʻahaʻa haʻahaʻa e hoʻomākeʻaka ana e hōʻike ana i nā kumuwaiwai ʻikepili heterogeneous e kaʻana like ana i ka ʻaoʻao like.

Hele mai kēia maʻalahi me kekahi mau kūʻai aku. ʻOiai ke hoʻopaneʻe nei mākou i ka hāʻawi ʻana o ka ʻikepili i kekahi ʻāpana o ka noi noi mākou e hoʻoili nei i kekahi o nā hoʻomohala i hana maʻamau ʻia e ka mea kākau hōʻike i kahi kanaka i loea i ka ʻenehana ʻike. E loli ka hoʻāʻo ʻana e ulana i ka ʻikepili i ka visualization ke hoʻohālikelike ʻia me ka kākau ʻana i kahi hōʻike kikoʻī pixel i nā keʻena kuʻuna Cognos. Pono ka poʻe hoʻolālā papahana e hoʻomaopopo i ka hopena o kēia ma nā timeline hoʻomohala. E ʻike kekahi he ʻoi aku ka pololei o nā kuhi ke ʻapo ʻia kēia mahele hou o ka hana.

I hōʻuluʻulu no kēia ʻāpana, ʻo ka Cognos Mashup Service kahi mea hoihoi i ka arsenal o nā pono hana i loaʻa i ka hoʻohuihui. Hāʻawi ia i ka ʻikepili BI e hele ma ʻō aku o ka haki ʻana wale i kahi , i loaʻa kahi mea nānā hōʻike, i loko o kahi ʻaoʻao HTML. Akā, ua aʻo mai ka manawa iā mākou ʻaʻohe mea no ka manuahi. Hiki ke maʻalahi o ka hōʻike ʻana i ka ʻikepili ma ka lilo o ka lawe ʻana i nā pūʻulu mākau hou i ka hoʻonohonoho hopena. E hoʻokuʻu i kēia ʻike i kahi manawa. I nā mea i kākau ʻia ma hope o kēia moʻo e loaʻa i ka ʻike kikoʻī e pili ana i ka hoʻohana ʻana i ka mashup a me ke ʻano o ka hōʻiliʻili kūʻē i nā moho hoʻonā ʻē aʻe.
