    <p>I'm getting ready to start the design of a database for a ASP.NET MVC application and I had a quick question about the best way to store information in a table.</p> <p>In the old version of my database, I had a table called <code>Phones</code> and It had around 40-50 different columns. </p> <p>Rather than having so many columns in a table, would you recommend keeping the "essential" data in the <code>Phones</code> table and then creating an additional table called <code>PhoneDetails</code> with the rest of the data?</p> <p>Thanks for your input!</p> <h2>Update</h2> <p>Here are the columns that are in my table: (there are 59 total)</p> <pre><code> [PhoneID] ,[Make] ,[Model] ,[ProcessorSpeed] ,[Dimensions] ,[Weight] ,[RAM] ,[Storage] ,[BatterySize] ,[TalkTime] ,[StandbyTime] ,[DisplayType] ,[Resolution] ,[DisplaySize] ,[RearCamera] ,[FrontCamera] ,[MinOS] ,[MaxOS] ,[NFC] ,[Notes] ,[Publish] ,[FullName] ,[Date] ,[Colors] ,[Sensors] ,[SIMCardType] ,[ChargingConnectors] ,[AVConnectors] ,[SystemConnectors] ,[USBVersion] ,[BluetoothVersion] ,[BluetoothProfiles] ,[WiFiVersion] ,[WiFiSecurityModes] ,[WirelessConnectivity] ,[GSMTypes] ,[GSMUpload] ,[GSMDownload] ,[LTETypes] ,[LTEUpload] ,[LTEDownload] ,[WCDMATypes] ,[WCDMAUpload] ,[WCDMADownload] ,[BatteryVoltage] ,[RemoveableBattery] ,[MaxMusicPlayback] ,[MaxVideoPlayback] ,[MaxWiFiTime] ,[ProcessorName] ,[ProcessorType] ,[RearAperture] ,[RearFocalLength] ,[RearMinFocusRange] ,[FlashType] ,[FlashOperatingRange] ,[FrontResolution] ,[FrontAperture] ,[DeviceGeneration] </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
