Introduction |
The SQC for Access utilizes the MS
Access as its engine. A generic relational
database have been developed as a Quality
Database. A relational
database is a collection of
data items organized as a set of
formally-described tables from which data
can be accessed or reassembled in many
different ways without having to reorganize
the database tables. In addition to being
relatively easy to create and access, a
relational database has the important
advantage of being easy to extend. After the
original database creation, a new data
category can be added without requiring that
all existing applications be modified.
A relational database is a set of
tables containing data fitted into
predefined categories. Each table contains
one or more data categories in columns. Each
row contains a unique instance of data for
the categories defined by the columns. The
tables can be connected together in a
relation to reduce the amount of data
entered.
The SQC for Access database is
divided into 4 layers. Plant, Equipment,
Measurement and Data. These are generic
names and can be re-assigned by the user to
a more logical name. |

Objective |
The
objective of this section is to provide step
by step instruction of how to set following
objectives in the database with
Administer Privileges.
Objective 1: Set the name
of the company to ABC Company.
Objective 2: Set the
database layers to the following convention.
|

Default Name |
New Name |
| A |
Plant |
Factory |
| B |
Equipment |
Product |
| C |
Measurement |
Measurement |
| |
Batch ID |
Production Order |
Objective 3: Suppose that you
have 4 factories, lets call them FA, FB, FC
and FD. Each has 3 product lines P1, P2, P3.
The all produce products that we can measure
length and width but not all
products are made in all of the factories.
The number of defects, length
and width are measured every 2
minutes.
