如何在Haskell中定义这些类型？

data FrontendDev = FrontendDev { html :: String, css :: String, javascript :: String }

data BackendDev = BackendDev { programmingLanguage :: String, database :: String, server :: String }

data SoftwareTester = SoftwareTester { testingFramework :: String, testAutomation :: String }

data Database = Database { relational :: String, NoSQL :: String }

data ServerAdmin = ServerAdmin { serverManagement :: String, monitoring :: String }

data CloudNative = CloudNative { containerization :: String, orchestration :: String }

data NetworkCommunication = NetworkCommunication { TCP :: String, UDP :: String }

data NetworkSecurity = NetworkSecurity { encryption :: String, authentication :: String }

data AudioVideo = AudioVideo { audioProcessing :: String, videoProcessing :: String }

data Multimedia = Multimedia { imageProcessing :: String, videoEditing :: String }

data ArtificialIntelligence = ArtificialIntelligence { machineLearning :: String, naturalLanguageProcessing :: String }

data InternetOfThings = InternetOfThings { sensors :: String, connectivity :: String }

data MobileDevelopment = MobileDevelopment { iOS :: String, Android :: String }

data Storage = Storage { fileStorage :: String, objectStorage :: String }

data Blockchain = Blockchain { distributedLedger :: String, smartContracts :: String }

data Metaverse = Metaverse { virtualReality :: String, augmentedReality :: String }
