organizationisachallengingtask.Inthisblog,wewillspecificallyfocus
onMongoDBanditsprosandconsforwebdevelopment.
WewillalsoseehowMongoDBperformsincomparisonwithMySQL,
whichisitsmajorcompetitor.So,let’sgetstarted!

3. What is MongoDB?
Fortheuninitiated,MongoDBisaDatabasemanagementsystemthatis
open-sourceandfree.ItisbasedonNoSQLandisveryusefulwhile
workingwithlargesetsofdata.
MongoDBcanbeusedforstorage,loadbalancing,complexdata
structuredescriptions,anddataintegration.
MongoDBprovidesuserswithaservertocreatedatabases,whichstore
recordsmadeupofcollectionsanddocuments.
ThefundamentalunitofdatainMongoDBisfieldandvaluepairs.The
basicdifferencebetweenMongoDB andRelationalDatabase
ManagementSystem(RDBMS)isthatitisnotarelationaldatabase.
Inthisblog,wewillspecificallydiscusstheadvantagesand
disadvantagesofMongoDBinwebdevelopment.

4. Use of MongoDBin Web Development
Webapplicationshavebeentraditionallyusingrelationaldatabases
primarily,butnowmoredevelopersareleaningtowardsalternative
optionslikeNoSQL.
MongoDB,whichisbasedonNoSQL,allowsthedevelopmentofscalable
anddata-drivenwebapps.Itisdesignedforhigh-speedread&write.
MongoDBhasascale-outarchitecturewhichiseasytoworkwithfor
developers.Theycanperformvariousfunctionslikesaving,updating,
extracting,andmanagingdatawithease.
YoucanretrievedocumentsinJSONformat,whichcanbereadby
humans.Thiscanalsobeusedforstoringcomplexdataobjects.

5. Pros of MongoDBNoSQLDatabase
DeveloperFriendly
MongoDBhasbeenbuiltinsuchawaythatdevelopersfinditvery
convenienttoworkwithit.
Itcanbeusedwithavarietyoflanguages,includingJava,C#,
JavaScript,RubyonRails,andPython.
Thisdatabasemanagementsystemconstantlygetsupdatedwithnew
features,andexcellenttechsupportisavailableforitscustomers.
AllyouneedtodoisclickafewtimesonthewebUI,andyoucanbegin
codingandcreatingclusters.Theon-premiseMongoDBdatabasecan
alsobemigratedtothecloud.

6. Scalability
MongoDBisscalableandcapableofhandlingtrafficsurgesvery
smoothly.Thisbasicallymeansthatprocessingisdistributedacross
severalcomputers.Itsupportshugevolumesofread-and-write
operations.
MongoDBusessharding,whichenablesstoringinformationclustersin
oneplace.However,dataitselfisstoredonseveralcomputerclusters.
Thisisexactlytheoppositeofrelationaldatabases,whichscalesupby
addingpowerfulcomputers.
MongoDBallowsobjectstobeembeddedwithinoneanotherviadata
modeling.Updationcanbedonethroughasingletransaction.
Severaldatabasetransactionscanbecombinedinonebatch,whichis
eitherrejectedorcarriedout.

7. ApplicationLifecycle

anythingalmostinstantly.Thedeveloperdoesnothavetobotherabout
thedocument’sstrictformat.
MongoDBprovidesfastdevelopment,andthereisnoneedforschema
synchronization.Therearestraightforwardpredeterminedsolutions.

8. Cons of MongoDB
Nothingisperfectinthisworld,andalthoughMongoDBhasobviouspros,
italsohassomecons.Let’shavealookatthem.
MemoryUsage
MongoDBhasunnecessaryusageofmemoryasitstoreskeynamesfor
allvaluepairs.Thereisnofunctionalityofjoinswhichcausesdata
redundancy.
NosupportforJoins
Unlikerelationaldatabases,thereisnosupportforjoins.Itcanonlybe
addedmanuallybycoding.However,thismayslowdowntheexecution.
LimitationonNesting
Documentscannotbenestedabovethe100level.

9. LimitationonDataSize
Documentsizecannotbemorethan16MB.
WriteLimit
MongoDBhasawritelimit,whichdetermineshowfastyoucanwriteto
thedatabase.Writesarerecordedonthemaster,whichislimitedbythat
particularmasternode’scapacity.
SecurityIssues
MongoDBdoesnothaveuserauthenticationenabledbydefault.Hackers
areknowntotargetunsecuredMongoDBdatabases.
Continuity
MongoDBhasanautomaticfailoverstrategywhichmeansthatifthe
mastermalfunctions,anothernodewillbecomeanewmaster.
However,thecatchisthatitwilltakeupto60secondsforthistohappen.
ThereareNoSQLdatabases,whichhaveseveralmasternodes.Ifone
goesdown,anotherisalwaysonstandby.

10. Comparison of MongoDB& MySQL
Architecture
MongoDBhasNexusarchitecturewhichcanofferhighscalability,flexible
schema,andglobalavailability.ItincludesdriversforAWS,Kubernetes,
andAzure,programminglanguageslikePythonandDjangoframework.
MySQLhasclient-serverarchitecturewithstorageoptimizedforhigh
performance.Itsdocumentationhasaperformanceoptimization
techniquemakinguseofconfigurationratherthanchangingSQL
measurements.

11. QueryLanguage
ThequerylanguageusedisMongoDBQueryLanguage(MQL),whichis
expressive.ItallowsCRUDfunctionslikecreate,updateanddelete.
Therearealsooptionsfortextsearch,geospatialqueries,anddata
aggregation.
MySQLusesSQLandcanbringdatafromtablesusingthejoin
functionality.Thisiswhatmakesitarelationaldatabase.SQLhasoptions
forDatadefinition,DataTransaction,DataManipulation,andData
Control.

12. Security
MongoDBoffersflexiblepermissionswhicharerole-basedforusersas
wellasfordevices.
Thispreventsaccesstounauthorizedpersonsandpreventscyber
attacks.ItalsosupportsTLS,whichstandsforTransportLayerSecurity,
andSSL,whichisSecureSocketsLayer(SSL).
MySQLhasprivilege-basedaccessandalsosupportsencryptionlike
MongoDB.Itallowsgrantingprivilegestouserstoaccessdatasetsand
operations.
Recently,MySQLhasaddeddualpasswordstoincreasesecurity.Itis
alsoconsideredmoresecureascomparedtoMongoDBduetoits
schemaandrigidarchitecture.

13. TransactionModel
InthecaseofMongoDB,theBASEmodelensuresthatdataisavailable
bycreatingreplicasacrossvariousnodes.Thereisnoimmediate
consistencyofDatavalues,althoughBASEmodelcanenforceit.
MySQL,ontheotherhand,goesbyACIDmodeltoensureconsistency.
ACIDstandsforthefollowingattributes:
Atomic:Eachtransactioniseithercompletelyhaltedorcarriedout
properly.
Consistent:Transactionsneveraffectthestructuralintegrityofthe
database.
Isolated:Notransactionaffectsanyothertransaction.
Durable:Evenifthereisanoutage,datarelatedtothetransactioncan
stillbefound.
Asthisensureshighsecurityandnofailedtransactions,financialservice

14. The Bottom Line…
