database - General Oracle Data Collection Storage -

-

I am preparing a new laboratory database. I want to store raw results together for all tests.

In some cases, the result is a single value. However, the result is sometimes a raw wave or signal.

The case below is the ideal (and why)? ... or provide your own ideal choice.

Option 1: Store each individual data as a separate result line (with offset from T = 0). Option 2: Create a signal_header table (start time, sample rate, units, etc.) that are linked to a raw_signal_value table (signal, offset index, value)

OR

OR

Option 3: Store raw data in an external file to recover it when necessary.

In addition, in the related post, I asked whether a normal result table is to be stacked in hair tables on the basis or not accurate and scale (data type).

I would like to avoid option 3 - if you are going to use to store raw results In a database, you can also use it to store all the results.

Option 1 sounds like you would duplicate a lot of data for each result line, and change only two values ​​(time offset and value).

Three options which you suggest, I go with Option 2. You will be able to store a singing result result line results for each result, and also the details of the results available in DB, without extending the result table itself

how you use the data and Based on how many statistics of the waveform you get per result, I would like the wave / signal to be a string (like the values ​​separated by a comma).

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
