1 CHALAPATHI INSTITUTE OF ENGINEERING & TECHNOLOGY CHALAPATHI NAGAR LAM,GUNTUR DEPARTMENT OF COMPUTER SCIENCE AND ENGINEERING INTRODUCTION ABOUT 'L2' LAB There are 30 systems (HCL) installed in this Lab. Their configurations are as follows: Processor : Intel Pentium D3.0 GigaHtz RAM : 512MB Hard Disk : 80GB Mouse : USB Optical Mouse Network Interface card : Present

2 Guidelines to Students Equipment in the lab for the use of student community. Students need to maintain a proper decorum in the computer lab. Students must use the equipment with care. Any damage is caused is punishable. Students are required to carry their observation / programs book with completed exercises while entering the lab. Students are supposed to occupy the machines allotted to them and are not supposed to talk or make noise in the lab. The allocation is put up on the lab notice board. Lab can be used in free time / lunch hours by the students who need to use the systems should take prior permission from the lab in-charge. Lab records need to be submitted on or before date of submission. Students are not supposed to use floppy disks Use of computer network is encouraged. LABS CONDUCTED IN L2 LAB: 1. DBMS LAB 2.OS LAB

3 Course Objectives DATABASE MANAGEMENT SYSTEMS LAB 1. Understand the role of a database management system in an organization. 2. Understand basic database concepts, including the structure and operation of the relational data model. 3. Construct simple and moderately advanced database queries using Structured Query Language (SQL). 4. Understand and successfully apply logical database design principles, including E-R diagrams and database normalization. 5. Design and implement a small database project using Microsoft Access. 6. Understand the concept of a database transaction and related database facilities, including concurrency control, journaling, backup and recovery, and data object locking and protocols. 7. Describe and discuss selected advanced database topics, such as distributed database systems and the data warehouse. 8. Understand the role of the database administrator. Course Outcomes 1. Able to master the basic concepts and understand the applications of database systems. 2.
