Hello everyone and good morning !
I am just working on one heur engine for crystal security and I am thinking of the DB type of the DB
Till now I was working with SQL,MySQL,Oracle and all of them are not the think that I want to have .
like Performance Read and Write I know MemSQl to but still lame can anyone suggest me something good in read most of it need to be in Read ?
 
Just read it in memory, it must be the fastest way :p

Make sure you only store small amount of data in memory / never assign string type into memory. Read the database file for each detection only for retrieve more information about the current detection.
 
yea I know this method but here we want to make the program work faster and to not use high memory usage or CPu and the method that you write about is using a lot

You know it? But you have misinterpretation about how system works . Read my previous comment, don't flood the memory with your signatures. If you want speed, play in memory and avoid/minimize I/O process. Before implementing how to read your signatures in file, you should consider to design how your AV detects any virus. My advice is after some flags has matched then engine is allowed to read the file. So, database file will be read if it is necessary.

you are right but the probem is not that .
At my last work we were working on something like huge Db viruses and etc and the product is on the top for years but most of the users are business users cuz normal pc can't take it yes you have 8 gb ram but the problems is not always there you have HDD and etc the program on start take 100% hdd before load db and afret that is the same ok little bit 30-40 % of the hdd is used by core functions yes the code of the program is big like 2 million and more line of code but here we want something new yes Baidu and 360 mau have some engine but i am working on something that's more good and dont have any influence on the system i am programr and security expert form years .
and i am working only because i want to see protected systems
