In writing this post we followed the Funds Database example in SQL Server OLAP Developer’s Guide by William C Amo published year 2000, check with Amazon if this is available. We like this example because it elaborated the process of populating the fact table very well.

The sql statement was executed to populate fact 2 fact tables (Please see funds Star Schema picture)
as follows;
1- Investments
2- Dividends

Sql statement for populating fact table Investments
select a.manager_num, M.office_num, f.fund_cd,f.fundacctno,t.trandate,
t.amount from accounts a INNER join managers m on a.manager_num=m.manager_num
inner join fundaccounts f on a.acct_no = f.ACCT_NO
INNER JOIN TRANHISTORY T ON (F.FUND_CD = T.fUND_CD) And f.fundacctno = t.fundacctno
Where t.trantype = ‘invest’

Sql statement for populating fact table Dividends
select a.manager_num, M.office_num, f.fund_cd,f.fundacctno,t.trandate,
t.amount from accounts a INNER join managers m on a.manager_num=m.manager_num
inner join fundaccounts f on a.acct_no = f.ACCT_NO
INNER JOIN TRANHISTORY T ON (F.FUND_CD = T.fUND_CD) And f.fundacctno = t.fundacctno
Where t.trantype <> ‘invest’

Creating four dimensions – Managers, Offices, Funds, and Accounts sions should be simple (Please see Funds OLTP Picture and Funds Star Schema), we will write more in our next post please feel free to add more o this topic.

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.

Microsoft® SQL Server™ 2000 systems have four system databases:

master
The master database records all of the system level information for a SQL Server system. It records all login accounts and all system configuration settings. master is the database that records the existence of all other databases, including the location of the database files. master records the initialization information for SQL Server; always have a recent backup of master available.

tempdb
tempdb holds all temporary tables and temporary stored procedures. It also fills any other temporary storage needs such as work tables generated by SQL Server. tempdb is a global resource; the temporary tables and stored procedures for all users connected to the system are stored there. tempdb is re-created every time SQL Server is started so the system starts with a clean copy of the database. Because temporary tables and stored procedures are dropped automatically on disconnect, and no connections are active when the system is shut down, there is never anything in tempdb to be saved from one session of SQL Server to another.

By default, tempdb autogrows as needed while SQL Server is running. Unlike other databases, however, it is reset to its initial size each time the database engine is started. If the size defined for tempdb is small, part of your system processing load may be taken up with autogrowing tempdb to the size needed to support your workload each time to restart SQL Server. You can avoid this overhead by using ALTER DATABASE to increase the size of tempdb.

model
The model database is used as the template for all databases created on a system. When a CREATE DATABASE statement is issued, the first part of the database is created by copying in the contents of the model database, then the remainder of the new database is filled with empty pages. Because tempdb is created every time SQL Server is started, the model database must always exist on a SQL Server system.

msdb
The msdb database is used by SQL Server Agent for scheduling alerts and jobs, and recording operators.

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,
)
GO
sp_bindrule id_chk, ‘cust_sample.cust_id’

An index is a structure RDBMS provides to improves the data processing. Your particular RDBMS program will determine how the index works and how you use it. How index has absolutely nothing to do with logical data structure and people often confuse it with term key.

Index and key are just two more terms that are widely and frequently misused throughout the database industry and in numerous database related publications – you’ll always know the difference between the two if you remember that keys are logical structures you use to identify records within a table and indexes are physical structures you use to optimize data processing.

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.

In this case Security departments overtime was calculated based on 12 hours and in all other departments base was 8 hours.

Salary was categorize by monthly type as [monthlytype] SG for Security Guard where ovetime was calculated based on 12 hours.

code is given below and was in included in select statement;

CASE monthlytype WHEN ‘sg’ THEN dbo.wrkshopattndnc.TOTAL_OVERTIME * dbo.[wrkshop employees].Salary / DAY(dbo.wrkshopattndnc.month)/12

ELSE dbo.wrkshopattndnc.TOTAL_OVERTIME * dbo.[wrkshop employees].Salary / DAY(dbo.wrkshopattndnc.month) / 8

END AS ovtamnt

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.

Precision is the number of digits in a number. Scale is the number of digits to the right of the decimal point in a number. For example, the number 123.45 has a precision of 5 and a scale of 2.
