Updating database tables from xml

I considered a basic Todo Application with minimal functionality like creating a todo note and assigning it under a tag(s) (category). Create a new class file under Database helper class contains all the methods to perform database operations like opening connection, closing connection, insert, update, read, delete and other things. So for this we just need three tables in the database. As this class is helper class, place this under helper package. So create another class named public class Database Helper extends SQLite Open Helper { // Logcat tag private static final String LOG = "Database Helper"; // Database Version private static final int DATABASE_VERSION = 1; // Database Name private static final String DATABASE_NAME = "contacts Manager"; // Table Names private static final String TABLE_TODO = "todos"; private static final String TABLE_TAG = "tags"; private static final String TABLE_TODO_TAG = "todo_tags"; // Common column names private static final String KEY_ID = "id"; private static final String KEY_CREATED_AT = "created_at"; // NOTES Table - column nmaes private static final String KEY_TODO = "todo"; private static final String KEY_STATUS = "status"; // TAGS Table - column names private static final String KEY_TAG_NAME = "tag_name"; // NOTE_TAGS Table - column names private static final String KEY_TODO_ID = "todo_id"; private static final String KEY_TAG_ID = "tag_id"; // Table Create Statements // Todo table create statement private static final String CREATE_TABLE_TODO = "CREATE TABLE " TABLE_TODO "(" KEY_ID " INTEGER PRIMARY KEY," KEY_TODO " TEXT," KEY_STATUS " INTEGER," KEY_CREATED_AT " DATETIME" ")"; // Tag table create statement private static final String CREATE_TABLE_TAG = "CREATE TABLE " TABLE_TAG "(" KEY_ID " INTEGER PRIMARY KEY," KEY_TAG_NAME " TEXT," KEY_CREATED_AT " DATETIME" ")"; // todo_tag table create statement private static final String CREATE_TABLE_TODO_TAG = "CREATE TABLE " TABLE_TODO_TAG "(" KEY_ID " INTEGER PRIMARY KEY," KEY_TODO_ID " INTEGER," KEY_TAG_ID " INTEGER," KEY_CREATED_AT " DATETIME" ")"; public Database Helper(Context context) @Override public void on Create(SQLite Database db) @Override public void on Upgrade(SQLite Database db, int old Version, int new Version) From now on we are going to add one by one method into Database Helper.class The function will create a todo item in todos table. It may prove more efficient (in terms of conversion costs) and easier to store the data in XML format.In content-based applications, the ability of the native XML database also minimizes the need for extraction or entry of metadata to support searching and navigation.An XML database is a data persistence software system that allows data to be specified, and sometimes stored, in XML format.

Third, you specify which rows will be updated using a condition in the WHERE clause.I have a separate blog post about the project here. You should consider getting to the SQL Server Reporting Services (SSRS) item contents via the Web Services provided with SSRS rather than extracting them directly from the database as I describe here.12/17/2011 – I have updated the Code Plex project project and included the SSIS project that extracts catalog contents directly to the file system! As SSRS is versioned the structure and storage methods used to manage the Report Server items may change, and the methods described here may no longer work.XML databases are a flavor of document-oriented databases which are in turn a category of No SQL database.Steve O'Connell gives one reason for the use of XML in databases: the increasingly common use of XML for data transport, which has meant that "data is extracted from databases and put into XML documents and vice-versa".

NOTE: Although the information discussed in this paper is (mostly) up-to-date, the idea that the world of XML and databases can be seen through the data-centric/document-centric divide is somewhat dated.
