I’m currently working on a simple Java application that calculates and graphs the different types of profit for a company. A company can have many branches, and each branch can have many years, and each year can have up to 12 months.
The hierarchy looks as follows:
-company
+branch
-branch
+year
-year
+month
-month
My intention was to have the data storage as simple as possible for the user. The structure I had in mind was an XML file that stored everything to do with a single company. Either as a single XML file or have multiple XML files that are linked together with unique IDs.
Both of these options would also allow the user to easily transport the data, as apposed to using a database.
The problem with a database that is stopping me right now, is that the user would have to setup a database by him/herself which would be very difficult for them if they aren’t the technical type.
What do you think I should go for XML file, database, or something else?
It will be more complicated to use XML, XML is more of an interchange format, not a substitute for a DB.
You can use an embeddedable database such as H2 or Apache Derby / JavaDB, in this case the user won’t have to set up a database. The data will be stored only locally though, so if this is ok for your application, you can consider it.
