An example of a data integrity mechanism is the parent and child relationship of related records. If a parent record owns one or more related child records all of the referential integrity processes are handled by the database itself, which automatically insures the accuracy and integrity of the data so that no child record can exist without a parent (also called being orphaned) and that no parent loses their child records. It also insures that no parent record can be deleted while the parent record owns any child records. All of this is handled at the database level and does not require coding integrity checks into each application.

This example creates a rule that performs the same function as the CHECK constraint example in the preceding topic. The CHECK constraint is the preferred method to use in Microsoft® SQL Server™ 2000.

CREATE RULE id_chk AS @id BETWEEN 0 and 10000
GO
CREATE TABLE cust_sample
(
cust_id int
PRIMARY KEY,
cust_name char(50),
cust_address char(50),
cust_credit_limit money,

In this example our client was facing an  issue where shipments are made  and C&F value amount is taken as Accounts Receivable, payments are received in 2 to 3  installments.  Management wants to know how much is outstanding against each shipment C&F Invoice.

In database invoice is generated on C&F basis where comprehensive information is recorded like invoice no,  Bill of Lading No, C&F Amount, Shipment NO and so on.

When Payments are received it is recorded exportpayments table along with shipment NO.

In order to create a report to what is outstanding against respective invoice we created a SQL Query  using select into Transact-SQL  as follows;

select sn1, sum(amt) as cfvl

 into #sd4

from dbo.exportpayments

group by sn1

Select Sn, CFvlu,sn1, cfvl, Cfvlu-cfvl as balance from

 dbo.invocesexpressions inner join #sd4 on

dbo.invocesexpressions.sn = #sd4.sn1

drop table #sd4

In the above example we selected Shipment NO SN1 and sum amount Sum(amt) as cfvlu

Into temp table SD4 and then we selected Shipment no SN, CFVLU from invoices table and CFVL from Temp table #SD4 and join Invoices table and #sd4 based on Shipment NO

At the end we dropped thetemp table  #SD4.

This example utilized the temp table for generating outstanding payments report.

We were getting answer like 8.67 products manufactured from 50 kgs of raw material. We talked to the manufacturing department they confirmed that 8 no of products are manufactured and 0.67 is the wastage. We calculated the weight of each product and then multiply by 8 which gave us the weight in kgs of 8 no of products.
After that weight of 1 product was multiplied with .67 of product and got the weight of wastage in kgs.
In the above scenario we needed the decimal value of .67 separated from 8.67 in separate column to show wastage. Our data was in SQL Server, we utilized the floor function to make 8.67 into 8 and then subtracted the 8 from 8.67. The issue was resolved by using floor function.

Below is the related information about Floor function as obtained from SQL Server books Online.

CEILING and FLOOR

The CEILING function returns the smallest integer greater than or equal to the given numeric expression. The FLOOR function returns the largest integer less than or equal to the given numeric expression. For example, given a numeric expression of 12.9273, CEILING returns 13, and FLOOR returns 12. The return value of both FLOOR and CEILING has the same data type as the input numeric expression.

Sometimes zip codes are missing or in one case we found data was separated using incorrect SQL functions resulting in erroneous data. Data scrubbing / cleansing a dirty data is always different in different companies.

We have a successfully accomplished various complicated tasks using various tools and SQL language.

Translating this to Data architecture helps defining the role of the data architect as the one responsible for developing and maintaining a formal description of the data and data structures – this can include data definitions, data models, data flow diagrams, etc. (in short metadata). Data architecture includes topics such as metadata management, business semantics, data modeling and metadata workflow management.

Then If we wanted to see all of the Employees from Marketing with the First name John,
ordered alphabetically, we could write:
 SELECT LastName, FirstName
 FROM view_marketingemployees
 WHERE Firstname = “John”
 ORDER BY FirstName

We can obtain the same results using derived table as follows;

By using derived tables, we could eliminate the view View_marketingemployees
as follows

 SELECT LastName, FirstName
 FROM
  (SELECT * FROM Employees
   WHERE department = “marketing”) AS marketing_EmployeesDerivedTable
 WHERE FirstName = “John”
 ORDER BY FirstName
