java database
hi i'm new to java. i want to create a java program to store edit etc data, so I'm thinking database. It would have to be accessible by 2 other pcs.
i was thinking mysql, but i read somewhere that javadb is an embedded java db, right. embedded means that it's contained with that program correct?
any help on links to tutorials on database would be great. thanks Ron G

Re: java database
If you embed the database, then any clients (your program) will have their local data, but different instances will not share the same data. If you wish the clients to share the data, then you will need some type of server running the appropriate software (MySQL is popular and installed by default on many commercial shared servers but there are also other options such as Derby, PostgrSQL, etc..).
If you wish to learn SQL, the see the following link:
SQL Tutorial
To make SQL calls from java, see the following
Trail: JDBC(TM) Database Access (The Java™ Tutorials)
Depending upon how scalable and maintainable you wish you app to be, its good practice to separate the data model, data logic and manipulation, and the user interface appropriately. This is typical of 3-tier designs in J2EE, modeled by the Model-view-controller
Re: java database
thank you so much for the reply..
forgive me, is derby already a part of java or is it a separate download??
Is derby easier than mysql to connect to?
Also can you in a laymens terms tell me what glassfish is, and should I look at this also..
Re: java database
Derby is a database and a separate download, deployed by Apache: Apache Derby All databases will have similar ways for connecting and performing SQL calls, so I wouldn't necessarily say one is better or easier than another.
Glassfish is an application server GlassFish - Open Source Application Server — Java.net from which you could place your application logic (for example you could run servlets or webpages which your client application retrieves data from, and those pages themselves - or something behind them - access the data).
Re: java database
There are many databases and all have same process of performing SQL calls. The Java database is easy to use. It is widely use because of allowing high security. It is portable and is install on one click. It is use in server client mode. It allows optional integration and gives high performance.
Re: java database
For Java Programming language Java Database is refer as JDBC. It shows the way how the user accessing the database. Java database provides methods for updating data. From a single application it accepts many implementations.
