Answer / anand
OLTP
* Is the E-R modleling,there are more concurrent users,
* It contains normalized tables so there is no redundancy.
* More tables,Joins and less Indexes,
* It stores daily transactional data
* It stores very less data
* It contains mainly current data
* INSERT,UPDATE,MODIFY can be applied on OLTP.
* Performace will be high
OLAP
* It is the Dimensional Modeling
* It contains Denormalised tables there will be redundancy.
* Less tables,Joins and more Indexes
* It stores operational data
* It contains Historical and Present data
* only SELECT clause is applied on OLAP
* It stores very Huge data
* Performance will be low compared with OLTP

OLAP - Online Analytical Processing, which deals with
analysis of data. It has to deal with historical data too (
for analysis purpose) Not updated frequently. If required
bulk update is allowed.
OLTP - Online Transactional Processing, which deals with
transactions. For e.g. withdrawals at ATM machines. It
involves many transactions. The databases have to be updated
more frequently after the successful completion of a
transaction.

OLTP
• Current data
• Short database transactions
• Online update/insert/delete

• High volume transactions
• Transaction recovery is necessary
• only one record is processed at a time
• data is present in 2d format
OLAP
•
• Current and historical data
• Long database transactions
• Batch update/insert/delete
• Denormalization is promoted
• Low volume transactions
• Transaction recovery is not necessary
• group of records processed at a time
• data is present in multi dim format

Answer / madhusudana rao
OLTP:
# OLTP means Online Transactional Processing, data comes
from different sources
# OLTP is normalized(3NF)
# it's used to stored the current transactional data
# it's store the less no of data
# here we will perform the DML operations
(INSERT,UPDATE,DELETE)
# performance is very fast
