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

Answer / jansi

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.

Answer / balaji

OLTP

• Current data
• Short database transactions
• Online update/insert/delete
• Normalization is promoted
• 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

Answer / madhusudana rao

OLAP:
# OLAP means Online Analytical Processing
# OLAP is denormalized
# it's containes current&previouse data and used for the
analytical purpose
# perfprmance processing is slow compare with OLTP
#it is used to store the large data

How can we improve performance?

I need to select the rows based on the latest 'Payment_due_date' column value. Let's say I have a Deski report with 3 columns: Payment_due_date, Cust_Name, Oustanding_Amt. Report is like this: ===================================== Payment_due_date,Cust_Name,Oustanding_Amt 02/28/11 , Bob, 115 03/31/11 , Bob, 90 02/28/11 , Mike, 120 02/28/11 , Susan, 220 05/31/11 , Bob, 80, 03/31/11 , Susan, 70 05/31/11 , Mike, 220 05/31/11 , Susan, 120 04/30/11 , Susan, 130 So,we would like to see (based on latest Payment_due_date) ================== 05/31/11 , Bob, 80, 05/31/11 , Mike, 220 05/31/11 , Susan, 120 Oustanding_Amt comes as SUM(Oustanding_Amt) from Universe. If we use Max(Payment_due_date),we do get one row but then, the column 'Oustanding_Amt' sums up. Not allowed to use do SQL Override .Context Operators aren't working. Thanks in advance:)
