I am developing a credit card applicatoin that will need me to produce my first large-scale MySQL database. I am presently getting a hard time wrapping my thoughts around the easiest method to organize it. Can anybody recommend any reading through materials that demonstrate various ways to arrange a MySQL database for various reasons?
I'd rather not try engaging in the particulars of the items I think of the database's primary components is going to be because I am not confident will be able to express it clearly enough to become useful at this time. This is exactly why I am just searching for some general assets on MySQL database organization.
Maybe I'm able to provide some advices based by myself experience
- unless of course very specific usage (like fulltext index), make use of the InnoDB tables engine (transactions, row securing etc...)
- specify the default encoding -
utf8is generally a sensible choice
- tweak the server parameters (*key_buffer* etc... lots of material around the Internet)
- draw your DB plan manually, talk to co-workers and developers
- define data types based not just around the programs usage, but additionally around the join queries (faster if types are equal)
- create indexes in line with the expected necessary queries, and to be talked about with developers
- plan a backup solution (according to DB replication, or scripts etc...)
- user management and access, grant just the necessary access privileges, and make up a read-only user for use by the majority of queries, that don't need write access
- define the server scale, disks (raid?), memory, CPU
Listed here are also some tips to make use of and make up a database.
Generate an income learned to operate this stuff out would be to stop making associations.
In additional object oriented languages (I am presuming you are using PHP?) that pressure OO, you learn how to think OO very rapidly, that is kind of what you are after here.
My workflow is much like this:
- Exercise what data you have to store. (Customer title etc.)
- Exercise the primary objects you are dealing with (e.g. Customer, Order, Sales rep etc), and assign all these a vital (e.g. Customer ID).
- Figure out which data connects that objects. (Customer title goes to some customer)
- See how the primary objects connect with one another (Sales rep offered to Customer)
After you have these, you've got a good object type of what you are after. The next thing is to check out the connections. For instance:
- Each client only has one title.
- Each product could be offered multiple occasions to anybody
- Each order only has one sales rep and something customer.
Once you have labored that out, you need to try something known as normalization, the art of having this assortment of data into a listing of tables, still reducing redundancy. (The concept is, a 1-to-one (customer title) is saved within the table using the customer ID, many to 1, someone to many and several to a lot of are saved in separate tables with certain rules)
That's virtually the gist from it, should you request for this, I'll scan a good example sheet from the workflow for you personally.
I'm able to recomend the first chapter of the book: An Introduction to Database Systems, assistance you organize your opinions, and that i certainly recomend not using fifth normal form but using fourth, this is important.
Basically could only provide you with one suggestion, that might be to create test data at similar volumes as production and benchmark the primary queries.
Just make certain the data distribution is realistic. (Not everyone is named "John", and never people have unique names. Not every people give their phone nr, and many people will not have 10 telephone numbers either).
Also, make certain the test data does not squeeze into RAM (unless of course you anticipate the development data volumes to complete too).
