Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

5. 1. Which TCP/IP port does SQL Server run on? How can it be changed?
SQL Server runs on port 1433. It can be changed from the Network Utility TCP/IP
properties.
2.What is OLTP (Online Transaction Processing)?
In OLTP - online transaction processing systems relational database design use the
discipline of data modeling and generally follow the Codd rules of data normalization in
order to ensure absolute data integrity. Using these rules complex information is broken
down into its most simple structures (a table) where all of the individual atomic level
elements relate to each other and satisfy the normalization rules.
3. What is SQL Profiler?
SQL Profiler is a graphical tool that allows system administrators to monitor events in
an instance of Microsoft SQL Server. You can capture and save data about each event to
a file or SQL Server table to analyze later. For example, you can monitor a production
environment to see which stored procedures are hampering performances by executing
too slowly.
Use SQL Profiler to monitor only the events in which you are interested. If traces are
becoming too large, you can filter them based on the information you want, so that only
a subset of the event data is collected. Monitoring too many events adds overhead to the
server and the monitoring process and can cause the trace file or trace table to grow very
large, especially when the monitoring process takes place over a long period of time.
6. 4. What are the authentication modes in SQL Server? How can it be changed?
Windows mode and Mixed Mode - SQL and Windows. To change authentication mode in
SQL Server click Start, Programs, Microsoft SQL Server and click SQL Enterprise
Manager to run SQL Enterprise Manager from the Microsoft SQL Server program group.
Select the server then from the Tools menu select SQL Server Configuration Properties, and
choose the Security page.
5. What is normalization ?
Normalization is a design technique that is widely used as a guide in designing relational
databases. Normalization is essentially a two step process that puts data into tabular form
by removing repeating groups and then removes duplicated data from the relational tables
(Additional reading recommended).
7. 6. What is meant by First Normal Form
A database is said to be in First Normal Form when all entities have a unique identifier or
key, and when every column in every table contains only a single value and doesn't contain a
repeating group or composite field.
7. What is meant by Second Normal Form
A database is in Second Normal Form when it is in First Normal Form plus every non-
primary key column in the table must depend on the entire primary key, not just part of it,
assuming that the primary key is made up of composite columns.
8 .What is meant by Third Normal Form
A database is in Third Normal Form when it is in Second Normal Form and each column
that isn't part of the primary key doesn't depend on another column that isn't part of the
primary key
9. When to denormalize ?
Typically, transactional databases are highly normalized. This means that redundant data is
eliminated and replaced with keys in a one-to-many relationship. Data that is highly
normalized is constrained by the primary key/foreign key relationship, and thus has a high
degree of data integrity. Denormalized data, on the other hand, creates redundancies; this
means that it's possible for denormalized data to lose track of some of the relationships
between atomic data items. However, since all the data for a query is (usually) stored in a
single row in the table, it is much faster to retrieve.
8. 10. How can you performance tune your database ?
Denormalize your tables where appropriate.
Proper use of index columns: An index based on numeric fields is more efficient than an
index based on character columns.
Reduce the number of columns that make up a composite key.
Proper partitioning of tablespaces and create a special tablespace for special data types
like CLOB, BLOB etc.
Data access performance can be tuned by using stored procedures to crunch data in the
database server to reduce the network overhead and also caching data within your
application to reduce the number of accesses.
9. 11. How will you map objects to a relational database ? How will you map class
inheritance to relational data model ?
Due to impedance mismatch between object and relational technology you need to
understand the process of mapping classes (objects) and their relationships to tables and
relationships between them in a database. Classes represent both behavior and data whereas
relational database tables just implement data. Database schemas have keys (primary keys to
uniquely identify rows and foreign keys to maintain relationships between rows) whereas
object schema does not have keys and instead use references to implement relationships to
other objects.
10. 12. What is a view ? Why will you use a view? What is an aggregate function ?
View is a precompiled SQL query, which is used to select data from one or more tables. A
view is like a table but it doesn’t physically take any space (i.e. not materialized).
Views are used for
Providing inherent security by exposing only the data that is needed to be shown to the end
user.
Enabling re-use of SQL statements.
Allows changes to the underlying tables to be hidden from clients, aiding maintenance of
the database schema (i.e. encapsulation)
Views with multiple joins and filters can dramatically degrade performance because views
contain no data and any retrieval needs to be processed.
The solution for this is to use materialized views or create de-normalized tables to store
data. This technique is quite handy in overnight batch processes where a large chunk of
data needs to be processed. Normalized data can be read and inserted into some temporary
denormalized table and processed with efficiency.
13. What is a database trigger ?
A trigger is a fragment of code that you tell to run before or after a table is modified. There
are typically three triggering EVENTS that cause trigger to 'fire':
INSERT event (as a new record is being inserted into the database).
UPDATE event (as a record is being changed).
DELETE event (as a record is being deleted).
Triggers can restrict access to specific data, perform logging, or audit access to data.

14. How can you keep track of all your database changes ?
If you want to keep track of all changes to a particular record, such as who
modified the record, what kind of modification took place, and when the record
modification occurred then you can use triggers because you can capture every
action that occurred on a particular table. For example, an INSERT trigger would
fire when a particular database table has a record inserted.
15. What is the difference between “Stored Procedure” and “Function”?
A procedure can have both input and output parameters, but a function can only
have input parameters.
Inside a procedure we can use DML (INSERT/UPDATE/DELETE) statements. But
inside a function we can't use DML statements.
