Oracle 10g & D2K Online Training

 

Learn to create robust and powerful applications with Khamur IT Solutions Pvt [L] Oracle Database Training. Oracle D2K is the frontend in oracle to develop forms and the backend database oracle would be storing information and d2k will be displaying it. Khamur IT Solutions Pvt [L] provides oracle 10g d2k training according to the current requirement of IT industry. Oracle Developer Suite is a suite of development tools released by the Oracle Corporation. A database management system, or DBMS, database management systems include dBase, Paradox, IMS, and Oracle. These systems allow users to create, update, and extract information from their databases. Compared to a manual filing system, the biggest advantages to a computerized database system are speed, accuracy, and accessibility..

You Will Learn How To:

• Develop efficient PL/SQL programs to access Oracle databases
• Create stored procedures and functions for reuse and maintenance
• Design modular applications using packages
• Manage data retrieval for front-end applications
• Invoke native dynamic SQL to develop high-level abstract code
• Improve performance with collections and bulk operations

Hands-On Experience Includes:

• Encapsulating data manipulation statements in stored procedures
• Performing complex data manipulation with explicit cursors
• Leveraging EXCEPTIONs for graceful handling of runtime errors
• Creating triggers to handle data integrity and derivation
• Utilizing weak and strong cursor variables for dynamic SQL

These topics will be covered in online class. After completion of 55% of course, student will go through Live Project Training, Interview Preparation and Recruitment process in Software Industry.
