sql - database design, question about implementation -

-

question regarding sql database design project working on.

i receiving data every few seconds , going need store data database. using mysql dbms. data needs stored in database userid attached each piece of data. handling 1 user per application. so, each instance of application handling 1 users data. remote database storing users data though. so, why need userid's know data whose.

my idea wait until receive 50 data packets , create delimited string of 50 data packets. (maybe separated commas) push string database along userid. , store data that. question is, way it? there better way? bad practice? tips please! =)

i receiving lot of data. 1 data packet every second, faster. let me know think.

the dbms running on remote machine. application running on android phone.

thanks in advance!

i not suggest concatenating bunch of values send delimited string database. creates additional work on database parse string.

any reasonable framework interacting database let create , send batches of sql statements different values bind variables database. keeps nice, friendly syntax of stored procedure or insert statement, keeps database normalized, , accomplishes performance goal of minimizing number of round-trips.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
