1784-CP101784-CP101784-CP101、数据的***方式实时数据库可以简单地理解为它是这样的数据库：由测点信息库、实时数据库、历史数据库三个数据库组成。测点信息库含有一个测点基本信息字段的一张表，这个表以测点标签作为关键字，对应一条测点基本信息的记录包含一条测点的基本配置信息，如压缩偏差，例外偏差，测点描述等。用户可从此数据库中查询测点的基本信息。实时数据库是内存快照数据库，反映了生产实时数据的时间戳、数值、质量等秒级变化。用户可从此数据库中查询生产实时数据的实时数据值（值，时间戳，质量）。历史数据库是含有一个以测点名称字段和时间字段为关键字的一张表，这张表的另外的一个重要的字段就是数值字段，用来存储测点的采集值，除了这些字段，还可以包含数据的状态，数据质量字段等。随着时间的变化，不断地将实时数据库中的实时数据进行压缩过滤，并更新磁盘历史数据文件中的表里的数据。用户可从此数据库中查询生产实时数据的历史样本值或历史插值数据。而对于关系数据库则是根据各个实体之间的关系来设计数据表的。※推荐品牌：※推荐公司Allen-Bradley厦门泰尼电气有限公司Schneider联系人：小黄（销售代表）Triconex固定电话：0592-6809319FOXBORO***:2917675397ABB邮箱：2917675397@***.comSIEMENS传真：0592-6890859MOTOROLA网址：www.xmtaini.comXYCOM地址：厦门海沧街道滨湖一里7号RexrothIndramat邮编：361026手机：18950191386NortelNTGZ70BAdualradioMFRM31900MHZNORTELNTNQ96AGNTNQTwoPortSTM1opticalChannelizedNortelBCM4004.0BCM400R4.0R41000vmdualPS/HDNortelNTHW86CB4POC12***lrAtmNortelNT0H15CDOPTera5200MOTR10GGBE/FC,B3***,1550NortelDS1404092-e5PASSPORT8648GTRSWITCHNORTELOPTERANT0H18DA5200OCLDB-BANDWMTM70BNortel,AL1001E12-E5ERS5698TFDW/96GETH2PORTs1..NortelDS1404055-E5PASSPORT8632TXMROUTINGSWCHMODNortelDS1404103-E5PASSPORTMETRO8692OMSFSWCHNortelBCM400Bundle(8x32x0x2+VM32)Nortel,WL81LC128WLAN8100128APLICUPGRADENortelPassport8010DS1404055-8632TXMEthernetRoutiNEW***AYANORTELBCM4506.0r6r6.064vm64um65ipNortel,WL81MG256WLAN8100MANAGEMENTS/WADD256APSNTCA01ZKOC-192TX1560.61NortelOpteraNortelUMTSRNCRadioNetworkControllerSHELFNTW859AFNORTELIPSEC250USERLIC.AGREEMENTFOR***APPLIANCENortel8394SFDS1404099-E5IPUIA6FWAA10GSwitchFabNORTELNT0H34AAOPTERAMETRO5200PERBANDEQLRWMC990HNortelAL1001E11-e5BaystackRoutingswitch5698tfdNewNortelDS1404060-E5PASSPORT8683PO***3PTMDABASEBOARDNortelBCM200Bundle(8x32x0x2+VM32)Nortel,NTC06603BUE5NABCM4506.0STD32IPSTATIONNortelPassport86108692SF8616SXE8608GBESwitchNortel8660SDM2IDSModuleDS1404086-E52FE+2IDSNortelAlteon2216EEB1412029E52216EApplicationSwitNortelBCM450BCM450Rls1Bundle-NTC06002BUE5Nortel,NTC06602BUE5NABCM4506.0STD-32DGITLSTAT..NortelNTNQ24AAOne-portDS3FunctionProcessorNEWNortelApplicationSwitch3408EDCEB1412022E5-NIB(!)NortelDS1402001-e5801010SLOT-chassisnewinboxNEWNORTEL***AYAAL1001E11-E5NortelNetworksNTK526BAE5NetworkingModuleNortelDS1404065-e58692sfROUTINGSWITCHMODULENORTELMODULEETHERNET1GBPS8-PORTSDS1404036newNortelDS1404059PASSPORT8608GBMSwitchNortelDS1404063-e58630GBRroutingswitchmoduleNewNortelNorstarMICS8x32Systemw/CallPilot100VoicemNORTELSWITCHETHERNET1000MBPS16-PORTSDS1404011NortelShasta5000BSNNTJT10AABroadbandServiceNodeNortelBCM400Bundle(4x16x0x2+VM16)Nortel,AL1001E13-E5ETHERNETROUTINGSWITCH5650TD-P..NEW***AYANORTELBCM4506.0BCM450r6r6.01000VMNortelNetworksNTK526MAE5NetworkingModuleDTE/DTCNORTELNT6X01AD/AC/BADMSEQUIPMENTNortelNorstarPhoneSystemT1x32,CallPilot,T7316eNortelEB1639128Alteon5114firewallswitchnewsealedNortel8310DS14020076x8324GTR2x8393SFEthRoutSwNortelPassport86108692SFEthernetRoutingSw8616SXENortelMeridianOption11cw/8-PortMeridianMail&NORTELNTZC72AADualPortDTI/PRIPKG+CablesNortel,NTC06611BUE6GLOBALBCM4506.0REDUNPWRCORD..Nortel5016EB1639130-E5SwitchedFirewallNEWNIBNortelBCM4003.7BaseSystem2LANRedundantNortelBCM4004.0BCM400R4R4.037vm20ip25umICCNortelBCM4004.0BCM400R4.0R480vmICCdualPS/HDNortelNTT870AJE5/WMDDZU0FABAgilestar-AA1403006-E5-ForNortel-NewinBoxNortelPassportOpteraNTCA15CAC-BandDualAmpCardNortelNetworksRMCL1312001-RemanRmrb5720mAtmMdaNortelWLANSecuritySwitch23821PortDR4001E80E5NEWNEWNORTEL8630GBR30PORTSFPMODULEDS1404063-E5Nortel83064x8348GTX-PWR8393SFEthernetSwitchPOEALTEON2424EEB1412026-E5NortelAS2424EEB1412026E5Nortel,AL1001E05-E55520-48T-PWRETHERNETROUTINGSW..IBMNORTEL10GBETHERNETSWITCHMODULEFOR39Y9267Nortel,AL1001E14-E5ETHERNETROUTINGSWITCH5650TD4..Nortel/***ayaNT4N39AAE5CP4cardNortel,AL1001E03-E5ERS5510-48TINCLUDEDN/APOWERNortelAL1001E05-E5Switch&BridgeNORTELSWITCHETHERNET1GBPS8-PORTSDS1404038NORTELBCM1000BUNDLE(8X32X0X2+VM32)NORTELSWITCHETHERNET10/100MBPS48-PORTSDS1404056NortelBCM4003.7BCM400R3.7108vm64umCallCenterNortelBCM4004.0BCM400R4R4.064vm64um65ipRefNORTELBAY(SEEDESCRIP)$5000NortelNTCA15CAC-BANDCARDPassportOpteraNortelPassport7480MultiserviceSwitchNTJS63LotofNortelCa***IntelliSystemNT7R52AENT8D02EANTNORTELDR4001103E62330BWLANACCESSPOINTLOTOF31Nortel3408ApplicationSwitchEB1412027E5EB1412027-E5NortelMOTR10GGE/FCVCATNortelNT0H03ECOPTeraOM5200AGILEOCLDB5CH31572.06NortelEB1639E170-E5SecureNTWKSwitchNEWNOB4050NortelNTBW89DAE5DOM-ACDMAEVDOTestedw/WarrantyNortelAlteon3408SwitchEB1412004AL34081YearWarranty-NoReasonableOffersEverRefused!NortelDS14040608683PO***DS13330048683POSOC3***FsetNortelContivity4600DM1401063NortelPassport83102x8393SF8x8348TXEthSwitchNortelAL4500E14-e6pwrswitch4548gt48portNEWAL4500A14-e6AL4500B14-e6AL4500C14-e639Y9267IBMNortel10GbEthernetBladeCenterSw39Y9266IBMNortel10GbEthernetBladeCenterSw39Y9265IBMNortel10GbEthernetBladeCenterSw32R1783IBMNortel10GbEthernetBladeCenterSwNIBNortelNT4N39AAE5PIVW/512MDDRCallProcessorNORTELNT0H17BAOPTERAMETRO5200OCLDB2CH1WMT9J40NortelNTNQ66AATwo-portOC3/STM-1ATMIPProcessorNEWNortelS8000G***BTSBaseStationCellsite1900MhzNortelBCM4003.7BaseSystem2LANStandard
