python - Realtime serial data logging with Python - design advice

Question

I am having to design a small program that reads the GPRMC sentence from a GPS logging device on a laptop computer. I am reading the raw values over serial connection. Once I read the raw value I will parse the GPRMC sentence (12 comma delimited values) and put them into a sqllite database so that another application can read them.

I was wanting some professional advice and some tips on implementation. The parts of the program I am wanting the most advice about are:

• Performance (does this seem like a very cpu intensive process?)
• Error checking (Need to think of all possible error states)
• Ease of updating (If I make a change to the code tree will it be easy to update the program)

Answer 1

取决于程序是否必须是可嵌入的。如果没有，Redis (http://redis.io) 有一个非常有效的时间序列实现。还有一个Django Dash 2011应用程序Staste可以做到这一点 - http://staste.unfoldthat.com/。我自己没有测试，但代码看起来不错，演示很有希望。
