    <p>It seems like a lot of unneccessary leg-work goes into manually coding a class file for each object to be stored in a database, as well as typing out by hand a whole DatabaseHelper class with all the necessary methods, etc.</p> <p>I have been trying to find a way to generate this all automatically by providing the minimum data - the required structure of the database. This should only need to be entered once, in one location. I have tried putting this in xml, declaring it in arrays, also in code annotations in object classes, but I have not found a solution to work for me.</p> <p>As an example of roughly what I'm trying to achieve, I could provide arrays as follows describing the desired structure of my database. NB Arrays with the suffix 'Cols' describe the columns desired in that table, suffix 'Opts' describes the required sqlite constraints for those columns.</p> <pre><code>static final String[] tables = {"Processes", "Machines", "Suppliers","machinesSuppliersLink"}; static final String[] processesCols = { // tables[0] "ProcessID" , "FullName" , "ShortName" , "Machines"}; static final String[] processesOpts = { "INTEGER PRIMARY KEY AUTOINCREMENT" , "TEXT" , "TEXT" , "INTEGER, FOREIGN KEY(Machines) REFERENCES Machines (MachinesID)"}; static final String[][] processes = { processesCols , processesOpts }; static final String[] machinesCols = { // tables[1] "MachinesID" , "Manufacturer" , "MachinesName", "Process" }; static final String[] machinesOpts = { "INTEGER PRIMARY KEY AUTOINCREMENT", "TEXT", "TEXT", "INTEGER, FOREIGN KEY(Process) REFERENCES Processes (ProcessID)" }; static final String[][] machines = { machinesCols , machinesOpts }; static final String[] suppliersCols = { // tables[2] "SuppliersID", "SuppliersName", "SuppliersPhone", "SuppliersWebsite", "SuppliersAddress", }; static final String[] suppliersOpts = { "INTEGER PRIMARY KEY AUTOINCREMENT", "TEXT", "INTEGER", "TEXT", "TEXT", }; static final String[][] suppliers = { suppliersCols , suppliersOpts }; static final String[] machinesSuppliersLinkCols = { // tables[3] "machinesSuppliersLinkID", "MachinesID", "SuppliersID" }; static final String[] machinesSuppliersLinkOpts = { "INTEGER PRIMARY KEY AUTOINCREMENT", "INTEGER, FOREIGN KEY(MachinesID) REFERENCES Machines (MachinesID)", "INTEGER, FOREIGN KEY(SuppliersID) REFERENCES Suppliers (SuppliersID)", }; static final String[][] machinesSuppliersLink = { machinesSuppliersLinkCols , machinesSuppliersLinkOpts }; public static final String[][][] schema = { processes , machines , suppliers , machinesSuppliersLink}; </code></pre> <p>Would somebody please help me by outlining the steps to automatically produce the necessary DatabaseHelper, classes, etc.</p> <p>Many thanks.</p> <p>PS I have a feeling that entering the above data vy creating a classes for each table would be a better starting point but felt the point would be illustrated clearer this way.</p>

    1. CO[I found this project which seems to be on the right track](http://code.google.com/p/sqlitegen/) but it has some pretty fatal flaws still unresolved according to the issues page. Something like this project would do great though I was actually imagining a solution in the application's java code itself.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
