 It is embedded in android by default.
 no need to perform any database setup or
administration task.
 Data is displayed in the logcat.
 For displaying data on the ListView OR
alert message.
 SQLiteOpenHelper class provides the
functionality to use the SQLite database.
T.ABIRAMI/KEC(Mobile application Development 3

Cursor class
 Retrieving data from SQLite databases in
Android is done using Cursors.
 The Android SQLite query method returns
a Cursor object containing the results of
the query.
 Cursors store query result records in rows
and grant many methods to access and
iterate through the records.

Methods
 moveToFirst() to position the Cursor
pointer at the first record
 moveToNext() function to iterate through
the records.
 isAfterLast() method performs a check to
see if the cursor is pointed after the last
record.
 When looping through records break the
loop when this becomes false.

This is the official tutorial from Oracle.httpdocs.oracle.comj.pdfjillisacebi75827

This is the official tutorial from Oracle. http://docs.oracle.com/javase/tutorial/jdbc/ Here is a good tutorial for getting started with SQLite. http://www.tutorialspoint.com/sqlite/sqlite_java.htm Chapter 34 in the Liang text. He uses MySQL. Getting started with SQLite might be a little easier, but he does a good job of defining the issues in not too many pages. For this assignment you can use SQLite OR MySQL. There are numerous videos in YouTube that demonstrate how to do this. Some are better than others. When you find one that is helpful, post a link to it on the discussion board. We have been working with the front-end (GUI), and the middle (creating and manipulating collections of objects), and now we will add on the back end. The persistent storage of data in your applications. This exercise is to get you comfortable with connecting to a DB, adding, deleting, retrieving data. I encourage you to play with this one, do more than the minimum. SQLite is a very small database. It is included by default in Android and iOS. It is surprisingly powerful for such a small footprint. It can be frustrating to see what’s going on – what is in the DB, did the query work correctly? MySQL is often called a community database. It belongs to Oracle, but they allow anyone to use it for free. The recent versions of the MySQL workbench that allows you to see what’s going on in your database are really very nice – starting to look like the Access front end. Create a connection to a relational database using SQLite or MySQL. Create a single database table to hold information. Let’s make a simple class called Person for this exercise. Person firstName (String) lastName(String) age (int) ssn (long) creditCard (long) Note that once you have the DB created, you don’t want to do this again every time you run your test program. The easiest way to deal with this – for this assignment, is to comment out the code that creates the DB creation and the table creation while you experiment with the following. (Aside: I choose ssn and credit card as fields here so that you might think about the persistent storage of sensitive data. There are some pretty strict laws governing the storage of some data. Please don’t use any actual social security numbers or credit card numbers in this exercise.) Demonstrate the insertion of a record into the database Insert several records. Write a method called insertPerson(Person person) that adds a person object to your database. Create another object of type Person, and demonstrate calling your method, passing the object to the method. Demonstrate the retrieval of information from the database. Use SQL Select statements, to retrieve a particular Person from the database. Write a method called selectPerson that returns a Person object. This method retrieves the data for a Person from the database. We also need to pass a parameter to identify what person. You can use ‘name’ if you like, or if you find it easier to use the database generated .

This study will provide the audience with an understanding of the capabilities of soft tools such as Artificial Neural Networks (ANN), Support Vector Regression (SVR), Model Trees (MT), and Multi-Gene Genetic Programming (MGGP) as a statistical downscaling tool. Many projects are underway around the world to downscale the data from Global Climate Models (GCM). The majority of the statistical tools have a lengthy downscaling pipeline to follow. To improve its accuracy, the GCM data is re-gridded according to the grid points of the observed data, standardized, and, sometimes, bias-removal is required. The current work suggests that future precipitation can be predicted by using precipitation data from the nearest four grid points as input to soft tools and observed precipitation as output. This research aims to estimate precipitation trends in the near future (2021-2050), using 5 GCMs, for Pune, in the state of Maharashtra, India. The findings indicate that each one of the soft tools can model the precipitation with excellent accuracy as compared to the traditional method of Distribution Based Scaling (DBS). The results show that ANN models appear to give the best results, followed by MT, then MGGP, and finally SVR. This work is one of a kind in that it provides insights into the changing monsoon season in Pune. The anticipated average precipitation levels depict a rise of 300–500% in January, along with increases of 200-300% in February and March, and a 100-150% increase for April and December. In contrast, rainfall appears to be decreasing by 20-30% between June and September.

Android SQLite database oriented application development

1. Android SQLite Dr.T.Abirami Associate Professor Department of IT Kongu Engineering College [email protected]

2. SQLite - Introduction  open-source relational database  i.e. used to perform database operations on android devices  such as storing, manipulating or retrieving persistent data from the database. T.ABIRAMI/KEC(Mobile application Development 2

3. SQLite - Introduction  It is embedded in android by default.  no need to perform any database setup or administration task.  Data is displayed in the logcat.  For displaying data on the ListView OR alert message.  SQLiteOpenHelper class provides the functionality to use the SQLite database. T.ABIRAMI/KEC(Mobile application Development 3

4. Cursor class  Retrieving data from SQLite databases in Android is done using Cursors.  The Android SQLite query method returns a Cursor object containing the results of the query.  Cursors store query result records in rows and grant many methods to access and iterate through the records.

5. Methods  moveToFirst() to position the Cursor pointer at the first record  moveToNext() function to iterate through the records.  isAfterLast() method performs a check to see if the cursor is pointed after the last record.  When looping through records break the loop when this becomes false.

6.  SQLiteDatabase db=openOrCreateDatabase("con.db", MODE_PRIVATE, null); T.ABIRAMI/KEC(Mobile application Development 6 Create a database in SQLite

7. T.ABIRAMI/KEC(Mobile application Development 7 Create a Table  db.execSQL("create table if not exists tblcon(cname,cmob);");

8. T.ABIRAMI/KEC(Mobile application Development 8 Insert a data  db.execSQL("insert into tblcon(cname,cmob) " + "values('"+strname+"','"+strmno+"');");

9. Reset data  name.setText("");  no.setText(""); T.ABIRAMI/KEC(Mobile application 9

10. View a one record at time String strname=name.getText().toString(); Cursor cr=db.rawQuery ("select cmob from " +"tblcon where cname='"+strname+"'", null); if(cr!=null) if(cr.moveToNext()) no.setText(cr.getString(cr.getColumnIndex ("cmob")));

11. Insert String strname=name.getText().toString(); String strmno=no.getText().toString(); db.execSQL("insert into tblcon(cname,cmob) " + "values('"+strname+"','"+strmno+"');"); name.setText("");no.setText(""); T.ABIRAMI/KEC(Mobile application 11

12. View String strname=name.getText().toString(); Cursor cr=db.rawQuery("select cmob from " + "tblcon where cname='"+strname+"'", null); if(cr!=null) if(cr.moveToNext()) no.setText(cr.getString(cr.getColumnIndex("c mob"))); } T.ABIRAMI/KEC(Mobile application 12

13. name=(EditText)findViewById(R.id.editText1); no=(EditText)findViewById(R.id.editText2); insert=(Button)findViewById(R.id.button1); t1=(TextView)findViewById(R.id.textView1); t2=(TextView)findViewById(R.id.textView2); view=(Button)findViewById(R.id.button2); db=openOrCreateDatabase("Info.db", MODE_PRIVATE, null); db.execSQL("create table if not exists tblinfo(cname,cmob)"); insert.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { String strname=name.getText().toString(); String strmno=no.getText().toString(); db.execSQL("insert into tblinfo(cname,cmob) " + "values('"+strname+"','"+strmno+"');"); name.setText(""); no.setText(""); } }); view.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { String strname=name.getText().toString(); Cursor cr=db.rawQuery("select cmob from " +"tblinfo where cname='"+strname+"'", null); if(cr!=null) if(cr.moveToNext()) no.setText(cr.getString(cr.getColumnIndex("cmob"))); } }); T.ABIRAMI/KEC(Mobile application 13
