Mwachidule kachitidwe kasamalidwe Nawonso achichepere

ntchito yonse ya anthu inextricably zogwirizana ndi zosiyanasiyana akalozera zambiri ndipo zinasokoneza makompyuta. The Library kaundula, polembapo, adilesi pa foni yanu kapena piritsi - uwu si mndandanda wa mfundo kusasintha, chimene ife ntchito. Koma makompyuta monga mwandondomeko, kotero ife kupereka tanthauzo.

Choncho, Nawonso achichepere (DB) - akonzedwa deta nawatsimikizira yofananako analongosola mkhalidwe mudziwe zinthu m'madera osiyanasiyana nkhani ndi kukonzedwa ndi zida kompyuta.

dongosolo Nawonso achichepere kasamalidwe ndi mapulogalamu ndi chinenero malo kulenga, kusamala ndi processing zapansi zambiri. Potumiza Nawonso achichepere:

• Ntchito ndi zapansi kunja (mbale, matepi, etc ...) ndi RAM;
• Kuuza ogwiritsa;
• kusintha kulamulira, archiving ndi Nawonso achichepere kuchira;
• kupereka mwayi kwa chinenero zambiri processing ;
• zida chilengedwe, kusinthidwa, ndi kasamalidwe Nawonso achichepere.

Mwachidule, Nawonso achichepere ndi Mzimuyo njira yosungirako, ndi Nawonso achichepere amapereka njira processing. Komanso, kachitidwe kasamalidwe Nawonso achichepere anawagawa dongosolo ambiri amagwiritsa ntchito akhoza kusamalira zosiyanasiyana deta ndi apadera lakonzedwa kuti nkhani yofunika kapena mtundu wa nkhani. Chitsanzo cha machitidwe apadera kasamalidwe Nawonso achichepere ndi chinthu olaula.

Chiyanjano Management System

Popeza Kubwera kwa zinasokoneza makompyuta kompyuta wakhala zitsanzo zambiri za ntchito yawo, koma chitsanzo ubale anali chilengedwe kwambiri. Ndi ofanana ya matebulo zambiri, kukutsimikizira wokhulupirika ndi redundancy osachepera zambiri. Table chitsanzo anali applicable kuti ambiri zokhudza maphunziro, ndi msika ndi ubale kasamalidwe dongosolo Nawonso achichepere anayamba mofulumira. chithunzi limasonyeza chitsanzo cha dongosolo ubale wa "m'munsi mwa ophunzira."

DBMSs onse ubale kuthandiza ANSI SQL chinenero muyezo ndi mfundo za chitsanzo ubale chomwe chimathandiza ntchito kuthamanga pa zinasokoneza makompyuta osiyana. Komanso, zinasokoneza makompyuta akuluakulu kuwonjezapo awo SQL magetsi. Zitsanzo za kasamalidwe dongosolo Nawonso achichepere ntchito zikuluzikulu - izi ndi Microsoft SQL Server ndi masomphenya.

Lachitsanzo ubale bwinobwino ntchito mu chitukuko cha ntchito Internet. Zitsanzo ndi MySQL Nawonso achichepere ndi PostgreSQL.

luso NoSQL

Kuwonjezeka mabuku deta ndi kuvuta ubale kwachititsa kuti zikamera wa machitidwe atsopano kasamalidwe Nawonso achichepere. Information watha muulamuliro wa wina ndi mzake, ndipo ngakhale kosatheka kuti mosamalitsa kufotokoza matabwa ake. zinasokoneza makompyuta Chiyanjano sangathenso kupirira ntchito zina. Izi zapangitsa kuti zikamera a mtundu watsopano wa zinasokoneza makompyuta mfundo ndi machitidwe kasamalidwe, pamodzi kudziwika monga NoSQL ( «palibe SQL»).

Magulu waukulu wa NoSQL zinasokoneza makompyuta:

1. "Ubwino Ofunika". Wotchuka kwambiri Nawonso achichepere - Redis, Voldemort, Tokyo nduna ndi Dynomite.
2. Oyeserera Nawonso achichepere BigTable. Iwo anayamba kupanga ndi Google kwa mkati ntchito search engine. mwalamulo BigTable Si anapereka, koma pali Nawonso achichepere pa maziko ake. Iwo Hadoop, Hypertable ndi Cassandra.
3. Chikalata zochokera. Wotchuka kwambiri Berkeley DB XML, MongoD, kulibe ndi CouchDB.
4. Kutengera pa tsinde la chiphunzitso Zithunzi. Ntchito Neo4j, Sones graphDB ndi AllegroGraph.

tsogolo la DBMS

Market ubale machitidwe kasamalidwe Nawonso achichepere chikukulirakulirabe ndi zambiri komanso amakonda kugwiritsa ntchito NoSQL kupanga. Kumene, mu "» SQL tingachipeze powerenga anagulitsa yaikulu kachitidwe pulogalamu ya osiyanasiyana Kuvuta, ndipo pali ngati msika zimphona monga Microsoft ndi masomphenya. Koma ndi zina ndithu tikhoza kuganiza kuti NoSQL mu zaka kudza adzatha kwambiri adzawathamangitsa atsogoleri chitukuko cha machitidwe nkhani zovuta.
