  • 1. *This image is take form Microsoft website By P. Sathish Kumar Senior Research Fellow, Defence Laboratory, Jodhpur 12th December 2008
  • 2. Outline of the talk • Introduction to the Subject – Database Rational Database – Object Rational Database – – Database Management System – History – Programming – SQL, – Connecting Java, Matlab to a Database  Advance DBMS • Data Grid • BigTable • Demo • Products • MySQL, SQLite, Oracle, DB2, Microsoft Access, Microsoft SQL Server • Products Comparison.
  • 3. Database  A database is a collection of data, typically describing the activities of one or more related organizations. For example, a university database might contain information about the following:  Entities such as students, faculty, courses, and classrooms.  Relationships between entities, such as students' enrollment in courses, faculty teaching courses, and the use of rooms for courses.

  • 5. Object Rational Database  In an object database (also object-oriented database), information is represented in the form of objects as used in object-oriented programming.  In Computer, Object is collecting of state(data) and behavior(processes). CREATE TYPE t_person AS OBJECT( CREATE TYPE t_address AS OBJECT ( id INTEGER, street VARCHAR2(15), first_name VARCHAR2(10), city VARCHAR2(15), last_name VARCHAR2(10), state CHAR(2), dob DATE, zip VARCHAR2(5) phone VARCHAR2(12), ); address t_address );
  • 6. Database Management System  A database management system, or DBMS, is software designed to assist in maintaining and utilizing large collections of data. The need for such systems, as well as their use, is growing rapidly.  The alternative to using a DBMS is to store the data in files and write application-specific code to manage it.
  • 7. History  early 1960 – Charles Bachman create first general-purpose DBMS General Electric late 1960 – IBM Created Information Management System (IMS) which is used  even today. 1970- Edgar Codd, at IBM's San Jose Research Laboratory, proposed a new data  representation framework called the relational data model. 1973 Bachman recived ACM's Turing Award (the computer science equivalent  of a Nobel Prize) for work in the database area 1977 Software Development Laboratories, the precursor to Oracle, is founded  by Larry Ellison, Bob Miner, and Ed Oates. 1978 Oracle Version 1, written in assembly language, runs on PDP-11 under RSX,  in 128K of memory 1980 - Dr. E.F. Codd Created Structure query language (SQL) for relational  databases, developed as part of IBM's System R project. 1990 …. Google Created BitTable for its Web Indexting Appliation .  

  • 9. SQL  Structured Query Language (SQL) is the standard language designed to access relational Databases.  SQL uses a simple syntax that is easy to learn and use  There are five types of SQL statements, outlined in the following list: 1. Query statements retrieve rows stored in database tables. SELECT statement.  2. Data Manipulation Language (DML) statements modify the contents of tables. There are INSERT adds rows to a table.  UPDATE changes rows.  DELETE removes rows. 
  • 10. SQL 1. Data Definition Language (DDL) statements define the data structures, such as tables,that make up a database. There are five basic types of DDL statements: CREATE creates a database structure.  ALTER modifies a database structure.  DROP removes a database structure.  RENAME changes the name of a table.  TRUNCATE deletes all the rows from a table. 
  • 11. SQL  Transaction Control (TC) statements either permanently record any changes made to rows, or undo those changes. There are three TC statements: permanently records changes made to rows.  COMMIT  ROLLBACK undoes changes made to rows.  SAVEPOINT sets a “save point” to which you can roll back changes.  Data Control Language (DCL) statements change the permissions on database structures. There are two DCL statements: GRANT gives another user access to your database structures.  REVOKE prevents another user from accessing your database  structures
  • 12. Conneting java to Database import java.sql.*; public class JDBCMain { public static void main(String[] args) { try { DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); String url = quot;jdbc:oracle:thin:@localhost:1521:ORCLquot;; Connection conn = DriverManager.getConnection(url, quot;scottquot;, quot;tigerquot;); stat = conn.createStatement(); String sql = “select * from emp”; rs = stat.executeQuery(sql); rsm = rs.getMetaData(); int colCount = rsm.getColumnCount(); for (int i=1; i <= colCount; i++) System.out.println(rsm.getColumnName(i) + “tquot;); while( rs.next( )){ for (int i = 1; i <= colCount; ++i) System.out.print( rs.getString(i) + “tquot;); System.out.println(“quot;); } conn.close(); }catch (SQLException sqlE){ conn.close(); System.out.println(sqlE.getMessage()); }catch (Exception e){ conn.close(); System.out.println(sqlE.getMessage()); } } }
  • 13. Conneting Database to MatLab  In Matlab Database conneting is done through Database Toolbox ds = ‘oracleODBC’ # ‘oracleODBC’ is the datasource name which is set using the # database toolbox sqlquery = ‘select * from emp’ conn = database (ds, ‘scott’, ‘tiger’) data = fetch(conn, SQLquery); if (isempty(data)) errordlg('No patients were found within that date range') close(conn); return end
  • 14. Advance DBMS DataGrid Google’s BigTable
  • 15. Data Grid  A data grid is a grid computing system that deals with data — the controlled sharing and management of large amounts of distributed data. These are often, but not always, combined with computational grid computing systems  Data Services  Single System Image  Data is present in the node with the process reside.  Less Data movement  More RPC Calls
  • 16. Type of Datagrid  Replicated Topology  Partitioned Topology  Near Topology
  • 17. Replicated Topology  Advantage:  Extreme Performance  Data is Replicated to all the member of the data grid  Less Latency Access: Data is avaliavle for use without any waiting  DisAdvantage:  Cost of data entry  Cost of data Update  No Scalability
  • 18. Partitioned Topology  Transpatently partition the data to distribute the load across all grid nodes  Advantage Extreme Scalability  Load Balancing  Ownership  Point to Point 
  • 19. Near Topology  Local in-Memory cache in front of the entire data set provide by the data grid  Advantage  Extreme Programming  Extreme Scalability  Less Latency Access
  • 20. Book Store
  • 21. Google’s BigTable  Bigtable is a distributed storage system for managing structured data that is designed to scale to a very large size: petabytes of data across thousands of commodity servers.  Google’s BigTable is implemented in C  Bigtable users:  Google Reader, Google Maps, Google Book Search, My Search History, Google Earth, Blogger.com, Google Code hosting, Orkut, and YouTube
  • 22. Data Model  • Doesn’t support a full relational data model  • Multi-dimensional sorted map  • Indexed by (row:string(64), column:string, time:int64) -> string  The row range for a table is dynamically partitioned. Each row range is called a tablet Row Key Time Sample Column “content” “anchor:cnnsi.comquot; anchor:my.look.caquot; “com.cnn.www” t9 “CNN” t8 “CNN.com” t6 “<html>…” t5 “<html>…” t1 “<html>…”
  • 23. Tablet Location  Use three-level hierarchy analogous to that of a B+ tree  - Location is of ip:port relevant server - 1st level: Bootstrapped from lock server, points to location of root tablet  - 2nd level: Uses META 0 data to find owner of appropriate META 1 tablet  - 3rd level: META1 table holds locations of tablets of all other tables 
  • 24. Use of BigTable As of August 2006, • 388 non-test Bigtable clusters • 24,500 tablet servers. (Many are used for development purposes) •14 busy clusters with 8069 total tablet servers •1.2 million requests per second, •incoming RPC traffic of about 741 MB/s •outgoing RPC traffic of about 16 GB/s.
