MySQL vs MS SQL Server
MySQL
MySQL yog qhov qhib qhov chaw tswj hwm qhov system. Nws yog nrov heev vim nws txoj kev ntseeg siab, kev siv yooj yim thiab kev ua haujlwm siab. MySQL yog siv rau ntau daim ntawv thov tshiab uas tau tsim rau Apache, Linux, Perl / PHP thiab lwm yam. Ntau lub koom haum nrov xws li Google, Alcatel Lucent, Facebook, Zappos thiab Adobe cia siab rau qhov kev tswj hwm database.
MySQL tuaj yeem khiav ntawm ntau tshaj nees nkaum lub platform uas suav nrog MAC OS, Windows, Linux, IBM AIX, HP-UX thiab muab kev hloov pauv ntau. Ntau yam ntawm cov cuab yeej database, kev pabcuam, kev cob qhia thiab kev txhawb nqa yog muab los ntawm MySQL database system. MySQL los ntawm ntau yam:
Enterprise Edition
tsab ntawv no muab OLTP (Scalable Online Transaction Processing) cov ntaub ntawv thov thiab tseem muab kev ua haujlwm zoo. Nws muaj peev xwm muaj xws li rollback, kab theem xauv, tag nrho kev cog lus thiab kev sib tsoo rov qab. Txhawm rau tswj hwm thiab txhim kho kev ua haujlwm ntawm cov ntaub ntawv loj, kev faib cov ntaub ntawv kuj tau tso cai los ntawm tsab ntawv no.
Cov Enterprise Edition suav nrog MySQL Enterprise Backup, Enterprise Monitor, Query Analyzer thiab MySQL WorkBench.
Standard Edition
tsab ntawv no tseem muab OLTP daim ntawv thov nrog rau kev ua haujlwm siab. Cov ntawv tshaj tawm kuj suav nrog InnoDB uas ua rau nws ua raws li ACID thiab kev lag luam-kev nyab xeeb database. Txhawm rau xa cov ntawv thov tuaj yeem ua tau thiab ua haujlwm siab, kev rov ua dua kuj tau tso cai los ntawm qhov system database.
Classic Edition
Nws yog qhov zoo tshaj plaws database system rau OEMs, VARs thiab ISVs uas siv MyISAM cia lub cav los tsim cov ntawv nyeem ntau heev. Cov ntawv classic yog siv tau yooj yim thiab xav tau kev tswj hwm tsawg. Txawm li cas los xij, tsab ntawv no tsuas yog rau VARs, ISVs thiab OEMs. Ib qho yooj yim tuaj yeem hloov kho mus rau cov ntawv tshaj tawm los ntawm cov ntawv classic.
SQL Server
SQL Server yog RDBMS (Relational Database Management System) tsim los ntawm Microsoft. Cov kab ke no ua haujlwm ntawm Transact-SQL uas yog cov txheej txheem txuas ntxiv los ntawm Microsoft thiab Sybase. T-SQL ntxiv lwm cov yam ntxwv uas suav nrog kev ua yuam kev thiab kev zam, kev tswj kev lag luam, tshaj tawm qhov sib txawv thiab kev ua kab. Txawm li cas los xij, Sybase tsim thawj SQL Server rov qab rau xyoo 1980s. Qhov kawg version yog hu ua SQL Server 4.2 uas tau tsim los koom tes nrog Ashton-Tate, Sybase thiab Microsoft rau OS/2.
SQL neeg rau zaub mov 2005 tau tsim tawm thaum lub Kaum Ib Hlis 2005. Cov qauv no tau muab kev ntseeg tau zoo dua qub, hloov tau yooj yim, kev ruaj ntseg thiab scalability rau database applications.
Cov yam ntxwv muab los ntawm SQL Server yog:
Database Mirroring - Siv SQL neeg rau zaub mov, ib qho tuaj yeem teeb tsa tsis siv neeg rov qab los ntawm cov neeg rau zaub mov standby.
Kev Ua Haujlwm Hauv Online Indexing - SQL Server kuj tso cai rau kev hloov kho ib txhij xws li ntxig, tshem tawm thiab hloov tshiab.
Management Studio - Kev tswj hwm studio yog txheej txheej ntawm cov cuab yeej uas tso cai rau cov neeg siv los xa, daws teeb meem thiab txhim kho SQL server databases.
Data Partitioning - Kev tswj hwm zoo ntawm kev ntsuas ntsuas thiab cov rooj loj yog muab nrog cov ntaub ntawv muab faib uas tau txhim kho nrog kev ntsuas qhov ntsuas thiab cov lus haiv neeg.
Rau Kev Lag Luam, SQL neeg rau zaub mov kuj tseem muab Kev Pabcuam Kev Sib Koom, Kev Pabcuam Tshaj Tawm, Cov ntaub ntawv tsuas, cov ntsuas kev ua haujlwm tseem ceeb, kev txhawb nqa pawg, kev txhawb nqa caching thiab repot tsev. Nws kuj tseem muab kev koom ua ke nrog Microsoft Office.
Zoo kawg, – MySQL yog qhov qhib qhov chaw tswj hwm qhov system whereas SQL Server yog tsim los ntawm Microsoft
– MySQL tuaj yeem khiav ntawm ntau dua nees nkaum lub platform thaum SQL Server tsis txhawb ntau lub platforms
