systemsa thata needa dataa toa bea kepta ina tables.a Applicationsa likea documenta storesa anda weba appsa
thata don'ta needa thea dataa toa bea structureda ina tablesa shoulda usea non-relationala databases.a Thea
relationshipa betweena programa designa anda dataa storagea designa isa thata theya worka togethera toa

thea relationshipa amonga thea differenta locations,a departments,a anda systems.a
Typesa ofa databases:
Clouda Databasea isa aa hostinga solutiona givena bya aa third-partya provider.a Ita isa aa pay-as-you-goa
solutiona minimalizinga initiala investmentsa neededa toa acquirea dataa spacea whilea expandinga asa
morea resourcesa area required.
On-premisesa databasea isa ana in-housea database.a Therefore,a alla thea software,a infrastructure,a anda

organizationa anda storage,a ensuringa accessibilitya anda integrity.
Relationala databasesa (e.g.,a MySQL,a PostgreSQL)a arrangea dataa intoa tablesa witha predefineda
schemas,a supportinga complexa relationships.a Theya excela ina scenariosa requiringa dataa integrity,a
likea financiala systemsa ora e-commercea platforms.a NoSQLa databasesa (e.g.,a MongoDB,a

area severala typesa ofa databasea outa therea buta SQLa anda NoSQLa isa thea mosta commona databasea
thata peoplea usea fora theira projects.a SQLa organizea dataa intoa tablesa witha predefinea relationshipa
betweena them.a wherea asa NoSQLa isa unstructureda databasea wherea ita doesa nota needa tablea toa bea

programa designinga anda thena dataa storagea designa isa reallya howa informationa maya bea handled.a
asa ifa letsa saya Ia wanteda toa designa aa dataa storagea facilitya toa justa bea onea biga dependency,a ita
woulda worka outa greata asa ita woulda providea aa lota ofa failsafe’sa fora aa companya tryinga toa keepa

youa willa bea lefta withouta thea informationa neededa toa performa thea joba ora documents.a Thisa isa
wherea let’sa saya youa havea 30a locations,a buta nowa therea isa 30a copiesa ofa thea samea filea acrossa thea
wholea networka makinga ita harda fora onea toa goa downa anda nota onea toa havea it.
Programa designa isa morea ofa thea physicala appearancea ofa thea programa fora thea enda usera anda howa
ita isa designeda internallya toa runa whilea ina use.a Thisa isa thea backa enda developinga ofa thea programa
anda thea physicala feela ofa thea programa toa thea user.a Thisa makesa ora breaksa aa website,a app,a game,a

collapsea ofa aa business,a game,a ora app.a Thisa isa aa fundamentala piecea whethera technilogicala ora
analyticallya speaking.
However,a thesea twoa maya havea differences,a theya area botha verya similar,a asa theya botha contributea
toa thea samea aspect,a youa cannota reallya runa anda deploya ana appa nowadaysa withouta aa
homestationa ina whicha youa cana providea updatesa toa saida app,a anda ifa youa doa nota havea aa dataa

thea programa design,a ita isa somethinga thata makesa aa companya looka good,a whethera ita bea
promotinga thea companya itself,a ora integrateda withina toa theira technologicala programs.a Dataa
storagea designa isa thea firsta simplea activitya thata isa lessa complex,a modular,a anda efficienta
programa structuresa thata isa thea designa activitiesa area listeda ina entity-relationshipa diagramsa
wherea thea informationa isa stored.a Thesea diagramsa area useda toa showa thea relationa betweena thea
variousa componenta ofa thea database.a na thea othera hand,a programa designa showsa howa dataa willa
bea howa thea organizationa willa developa thea programa itself.a Thisa involvesa severala stagesa thata area
thea research,a consultation,a initiala designs,a testing,a anda redesigning.a Ina termsa ofa relationshipa
betweena programa designa anda dataa storagea designa isa thata fora thea dataa storagea toa bea accesseda
ona theya botha musta worka simultaneouslya fora thea retrievala anda savinga ofa thea data.a Ina termsa ofa
dependenciesa thea programa designa musta meeta thea givena conditiona ofa thea dataa storagea designa toa
worka outa ina aa unisona anda thea programa designa isa responsiblea fora queryinga anda savinga thea dataa
ina thea dataa storage.Thea twoa typesa ofa databasesa area relationa anda non-relationa databases.a Ina
relationa databasea dataa isa storeda ina ana organizeda waya ina tablesa accordinga toa howa ita relatesa toa
eacha othera whilea ina thea non-relationa databasea dataa isa storeda ina aa non-tabulara waya thata isa
databasea willa usea differenta waysa fora managing,a accessing,a anda storinga thea data.a Accordinga toa
securitya onea prefersa toa usea thea relationa databasea sincea thea non-relationa hasa weaka securitya
whicha maya concerna thea largea scopea ofa dataa ina thea database.a Hencea onea prefersa toa usea thea
relationa fora securitya purposes.a Thea othera reasona isa thea typea ofa dataa toa bea storeda ina thea
databasea toa bea chosena thisa isa concerneda witha ana examplea ina aa schoola wherea studenta
informationa isa storeda ina aa database.a Toa ensurea thata ita willa enhancea thea easiera searcha ofa dataa
thea staffa willa choosea toa takea thea relation.a Sincea thea studenta informationa isa groupeda ina aa
similara waya hencea easiera toa search.a Thea relationshipa betweena programa designa anda dataa
storagea designa isa cruciala ina developinga efficienta anda functionala softwarea systems.a Thea criticala
aspectsa ofa thea programa designa dependenciesa includea thea dataa model,a dataa integrity,a anda
performancea considerations.a Thea programa designa heavilya dependsa ona thea dataa modela useda fora
storinga data.a Programa designa alsoa dependsa ona dataa storagea designa toa ensurea dataa integrity.a
Thea programa designa needsa toa considera thea performancea characteristicsa ofa thea underlyinga dataa
storagea design.Dataa storagea dependenciesa ona programa designa area Dataa structures,a Dataa
accessa anda manipulation,a anda Securitya anda privacy.a Thea dataa storagea designa reliesa ona thea
programa designa toa determinea thea requireda dataa structuresa fora efficienta dataa storage.a Thea
programa designa determinesa thea waysa dataa willa bea accessed,a queried,a anda modified.a Thea dataa
storagea designa needsa toa accommodatea thesea requirementsa bya providinga appropriatea accessa
methods,a APIs,a anda querya interfacesa thata aligna witha itsa needs.a Twoa typesa ofa databasesa area
relationala anda NoSQL.a Relationala databasesa area baseda ona thea relationala modela anda usea
structureda querya languagea (SQL)a fora dataa management.a Theya organizea dataa intoa tablesa witha
rows,a columns,a anda relationshipsa usinga keys.a Relationala databasesa commonlya storea producta

databases.a NoSQL,a whicha isa “nota onlya SQL”a isa designeda fora handlinga larger-scale,a
unstructureda data.a Theya offera flexiblea schemasa anda horizontala scalability.a NoSQLa databasesa
area commonlya useda fora storinga anda processinga largea volumesa ofa unstructureda data,a sucha asa
sociala mediaa feeds,a ora loga files.a Programa designa anda dataa storagea designa area closelya
interconnecteda ina buildinga ana efficienta anda functionala system.a Programa designa focusesa ona
creatinga thea logica anda structurea ofa softwarea applications,a whilea dataa storagea designa concernsa
thea organization,a storage,a anda retrievala ofa dataa withina thea system.
Thea relationshipa betweena programa designa anda dataa storagea designa liesa ina thea facta thata thea
programa designa dictatesa howa dataa isa processed,a manipulated,a anda utilizeda withina thea
application.a Thea programa designa determinesa thea dataa structures,a algorithms,a anda operationsa

storagea designa influencesa thea programa designa bya providinga thea necessarya structuresa anda
mechanismsa toa storea anda accessa thea dataa efficiently.
Whena ita comesa toa comparinga anda contrastinga twoa typesa ofa databases,a let'sa considera
Relationala Databasesa (RDBMS)a anda NoSQLa databases.
Relationala databases,a sucha asa MySQLa anda PostgreSQL,a organizea dataa intoa tablesa witha
predefineda schemas,a enforcea dataa integritya througha constraints,a anda supporta powerfula
queryinga capabilitiesa usinga structureda querya languagea (SQL).a Theya area suitablea fora
applicationsa thata requirea stricta dataa consistencya anda complexa relationships,a sucha asa financiala
systemsa ora inventorya managementa systems.
Ona thea othera hand,a NoSQLa databases,a likea MongoDBa anda Cassandra,a providea aa flexible,a
schema-lessa dataa model,a allowinga fora easya scalabilitya anda handlinga ofa largea volumesa ofa
unstructureda ora semi-structureda data.a Theya excela ina scenariosa wherea dataa variabilitya anda high-
speeda dataa ingestiona area crucial,a sucha asa real-timea analytics,a contenta managementa systems,a ora
sociala mediaa platforms.
Thea choicea betweena thea twoa typesa ofa databasesa dependsa ona thea specifica requirementsa ofa thea
application.a Fora instance,a ifa youa needa toa maintaina stronga dataa consistencya anda havea complexa
relationshipsa betweena entities,a aa relationala databasea isa aa suitablea choice.a Ina contrast,a ifa youa
anticipatea aa needa fora horizontala scalability,a flexibilitya ina dataa schema,a ora handlinga largea
volumesa ofa unstructureda data,a aa NoSQLa databasea woulda bea morea appropriate.
Fora example,a ana e-commercea websitea thata needsa toa storea anda managea producta catalogs,a
customera orders,a anda inventorya levelsa witha complexa relationshipsa woulda benefita froma aa
relationala database.a Ona thea othera hand,a aa sociala mediaa platforma thata dealsa witha high-velocitya
dataa streams,a user-generateda content,a anda requiresa flexiblea schemaa toa accommodatea changinga
dataa structuresa woulda finda aa NoSQLa databasea likea MongoDBa morea suitable.a Aa dependencya
isa aa constrainta thata appliesa toa ora definesa thea relationshipa betweena attributes.a Ita occursa ina aa
databasea whena informationa storeda ina thea samea tablea uniquelya determinesa othera data.a Youa cana
alsoa describea thisa asa aa relationshipa werea knowinga thea valuea ofa onea attributea (ora aa seta ofa facts)a
isa enougha toa tella youa thea valuea ofa anothera featurea (ora groupa ofa attributes)a ina thea samea table.a
Databasea dependenciesa oftena needa toa bea clarifieda fora studentsa anda databasea professionals.a
Fortunately,a theya area nota asa complicateda asa theya maya seem.a Fora example,a aa completea
functionala dependencya occursa whena youa alreadya meeta thea requirementsa fora aa functionala
dependency,a anda thea seta ofa attributesa ona thea lefta sidea ofa thea functionala dependencya statementa
cannota bea reduceda anya further.a Fora example,a {SSN,a age}a namea isa aa functionala dependency.a
Still,a ita isa nota aa fulla functionala dependencya becausea youa cana removea agea froma thea lefta sidea ofa
thea statementa withouta impactinga thea dependencya relationship.a so,a Databasea dependenciesa area
importanta toa understanda becausea theya providea thea basica buildinga blocksa useda ina databasea
normalization,a thea processa ofa efficientlya organizinga dataa ina aa database.a Fora aa tablea toa bea ina
seconda normala forma (2NF),a therea musta bea noa casea ofa aa nonprimea attributea ina thea tablea thata isa
functionallya dependenta upona aa subseta ofa aa candidatea key.a Designinga
Programa designa isa aa frameworka fora buildinga softwarea ora codinga programsa ina aa specifica
languagea thata helpsa toa createa softwarea ora applications.a Creatinga sucha aa modela requiresa aa
normalizeda databasea designa thata movesa froma thea logicala toa thea physicala process;a thea logicala
developsa thea technicala seta ofa rulesa anda dataa structures.a Thea physicala processa isa implementinga
thea database,a layinga thea groundworka fora incominga anda outgoinga dataa flows,a anda designinga
pathwaysa determininga dataa storage.a Botha modelsa representa thea designa layera fora applicationa
development.a Furthermore,a softwarea designa isa vitala ina understandinga thea technicala anda
operationala ofa thea programa anda gatheringa informationa abouta thea businessa need,a sucha asa
specifica aspectsa ofa usera anda systema interfaces,a databases,a anda networking.a
Database
Therea area variousa typesa ofa databases,a sucha asa MySQL,a Oracle,a Postgrea SQL,a anda Sybasea Aa
databasea isa aa collectiona ofa dataa ora informationa thata cana bea quicklya accesseda anda manageda
intoa rows,a columns,a anda tables,a anda indexinga helpa ina findinga relevanta information.
Relationala Database
Aa relationala databasea storinga dataa ina rowsa (tuples)a anda columnsa (attributes)a usesa SQLa toa
managea anda maintaina dataa storage;a thisa formata allowsa toa establisha aa linka betweena
information.a Thea attributesa area primarya keysa thata connecta toa eacha tuplea (row)a thata createsa aa
relationshipa toa eacha tablea usinga aa foreigna key.a (Whata isa aa relationala database?,a n.d.).a
Commonlya seena fora accountinga purposes,a ita isa easya toa use,a flexible,a anda maintainsa thea
transaction'sa accuracya beforea anda aftera thea transactiona historya databasea followsa thea ACIDa
properties.a Fora example,a whena transferringa fundsa betweena accounts.a Accounta Aa hasa $500.00a
anda wantsa toa movea $100.00a toa accounta Ba asa aa balancea ofa $200.00;a asa eacha transactiona passesa
betweena eacha account,a wherea databasea inputa anda outputa followa thesea propertiesa
hea dataa storagea designa willa dependa ona thea programa design.a Thisa isa especiallya truea owinga toa
thea facta thata thea programa designa willa affecta thea sizea asa wella asa howa toa accessa ita thereforea
affectinga howa thea dataa isa storeda ina thea program.a Therefore,a thea dataa storagea willa bea greatlya
affecteda bya thea programa design.a
Fora eacha uniquea structurala data,a therea isa thea creationa ofa differenta dataa store,a anda thisa impliesa
thata therea willa bea aa changea ina thea programa designa ofa thea programa ata handa ana examplea isa thea
differenta dataa storagea ina thea DASa anda thea NASa whicha causesa differencesa ina thea programa

Typea ofa databases:
Therea area twoa formsa ofa databasesa
Single-filea ora filea databasea
Thisa typea ofa databasea woulda bea useda ina thea eventa ofa storinga thea usernamea anda password,a
entitiesa anda attributes,a contacta details,a producta details.a
Multi-filea ora Structureda databasea
Thisa typea ofa databasea woulda bea useda ina scenariosa wherea therea isa aa needa toa storea thea
predictable,a structureda dataa whicha possessa aa finitea individuala ora aa finitea applicationa thata area
accessinga thea database.a Thea designa phasea transitiona froma aa logicala toa physicala processa werea
thea analysta starta toa layouta thea programa anda itsa dataa flow.a Thisa beginsa thea creationa ofa thea
relationshipsa betweena thea programa anda databasea designs.a Thea programa designa willa consista ofa
thea structure,a itsa purpose,a anda whata ita isa goinga toa accomplish.a Thea dataa storagea designa willa bea
