A database is usually controlled by a database management system (DBMS). MS Access is a popular DBMS that allows users to create and manage databases. The document discusses various components of a database such as tables, queries, forms and reports. It provides information on how to create an MS Access database, add tables, enter data, create relationships between tables, write queries to extract data, and build forms and reports. The key aspects covered are data modeling using entity relationship diagrams, normalizing data to reduce redundancy, and performing common database operations like importing, exporting and analyzing data in MS Access.

Whenever you make a list of anything – list of groceries to buy, books to borrow from the library, list of classmates, list of relatives or friends, list of phone numbers and so o – you are actually creating a database.
An example of a business manual database may consist of written records on a paper and stored in a filing cabinet. The documents usually organized in chronological order, alphabetical order and so on, for easier access, retrieval and use.
Computer database are those data or information stored in the computer. To arrange and organize records, computer databases rely on database software

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

2. As the data consist of raw facts so as to transfer data into useful
information it must be organized in a meaningful way. So as to
organize data a database is used. A database is an organized
collection of structured information, or data, typically stored
electronically in a computer system. A database is usually
controlled by a database management system (DBMS). The data
can then be easily accessed, managed, modified, updated,
controlled, and organized. Example: Student identity, Employee
identification, and many more. There are also several database
system available in market.eg. Relational database, Distributed
database , etc
DEFINITION OF DATABASE
What is database?
3. Database Components
There are five main components of a database:
Hardware:
The hardware consists of physical, electronic devices like computers, I/O
devices, storage devices, etc. This offers the interface between computers
and real-world systems.
Software:
This is a set of programs used to manage and control the overall
database. This includes the database software itself, the Operating
System, the network software used to share the data among users, and
the application programs for accessing data in the database.
Data:
Data is a raw and unorganized fact that is required to be processed to
make it meaningful. Data can be simple at the same time unorganized
unless it is organized. Generally, data comprises facts, observations,
perceptions, numbers, characters, symbols, images, etc.
Procedure:
Procedure are a set of instructions and rules that help you to use the
DBMS. It is designing and running the database using documented
methods, which allows you to guide the users who operate and manage it.
Database Access Language:
Database Access language is used to access the data to and from the
database, enter new data, update already existing data, or retrieve
required data from DBMS. The user writes some specific commands in a
database access language and submits these to the database.
4. Entity Relational Model
(E-R Model)
ER Diagram stands for Entity Relationship Diagram, also
known as ERD is a diagram that displays the relationship of
entity sets stored in a database.
ER diagrams are created based on three basic concepts:
entities, attributes and relationships. ER Diagrams contain
different symbols that use rectangles to represent entities,
ovals to define attributes and diamond shapes to represent
relationships
8. DBA Database Administrator
A database administrator (DBA in DBMS) is a group of
professionals that use specialize software to perform
all activities related to designing, maintaining, creating,
and running efficient and cost-effective databases and
environments.
THEIR JOBS COULD INCLUDE:
Capacity planning
Database design
Migration
Backup & Data Recovery
Installation
Configuration
Performance monitoring
Security Management
9. A database is usually controlled by a database
management system (DBMS).
DEFINITION : Software that handles the storage, retrieval, and updating of data in a
computer system.
Database Applications: 1. Banking: all transactions
2. Airlines: reservations, schedules
3.Universities: registration, grades
4.Sales: customers, products, purchases
5.Online retailers: order tracking, customized recommendations
6.Manufacturing: production, inventory, orders, supply chain
7.Human resources: employee records, salaries, tax deductions
10. Advantages and Disadvantages
of DBMS
•DBMS offers a variety of techniques to store &
retrieve data.
•DBMS serves as an efficient handler to balance the
needs of multiple applications using the same data.
•A DBMS uses various powerful functions to store
and retrieve data efficiently.
•Offers Data Integrity and Security.
•A DBMS schedules concurrent access to the data
in such a manner that only one user can access the
same data at a time.
•Reduced Application Development Time.
•Cost of Hardware and Software of a DBMS is quite
high which increases the budget of your organization.
•Most database management systems are often
complex systems, so the training for users to use the
DBMS is required.
•In some organizations, all data is integrated into a
single database which can be damaged because of
electric failure or database is corrupted on the storage
media.
•Use of the same program at a time by many users
sometimes lead to the loss of some data.
•DBMS can’t perform sophisticated calculations.
Advantages Disadvantages
11. Microsoft Access
Microsoft Access is a database management system from Microsoft
that combines the relational Microsoft Jet Database Engine with a
graphical user interface and software-development tools.
Microsoft Access stores information which is called a
database. To use MS Access, you will need to follow
these four steps −
•Database Creation − Create your Microsoft Access database and
specify what kind of data you will be storing.
•Data Input − After your database is created, the data of every
business day can be entered into the Access database.
•Query − This is a fancy term to basically describe the process of
retrieving information from the database.
•Report (optional) − Information from the database is organized in a
nice presentation that can be printed in an Access Report.
12. MS Access - Create Database
To view the all the possible databases, you can scroll
down or you can also use the search box.
Let us enter project in the search box and press Enter.
You will see the database templates related to project
management.
To create a database from a template, we first need to
open MS Access and you will see the following screen
in which different Access database templates are
displayed.
Select the first template. You will see more information
related to this template. enter a name in the File
name field and you can also specify another location
for your file if you want. Press the Create option.
Access will download that database template and open
a new blank database
13. Datatypes
SHORT TEXT : Alphanumeric data (names, titles, etc.)
LONG TEXT : Large amounts of alphanumeric data sentences and paragraphs.
NUMBER : Numeric data.
DATE/TIME : Dates and times.
CURRENCY : Monetary data
AUTONUMBER : Unique value generated by Access for each new record.
YES/NO : Boolean (true/false) data.
OLE OBJECT : Pictures, graphs, or other ActiveX objects from another Windows-based
application.
HYPERLINK : A link address to a document or file on the Internet, or on your local computer
ATTACHMENT : You can attach files such as pictures, documents, spreadsheets, or charts.
CALCULATED : You can create an expression that uses data from one or more fields.
LOOKUP WIZARD : . When you choose this entry, a wizard starts to help you define either a
simple or complex lookup field.
14. Databases in Access 2010 are composed of four
objects: tables, queries, forms, and reports. Together,
these objects allow you to enter, store, analyze, and
compile your data however you want.
TABLES : Tables are database objects that contain all the data in a database. In tables, data is
logically organized in a row-and-column format. Each row represents a unique record, and each
column represents a field in the record.
QUERIES: A query is a request for data or information from a database table or combination of tables.
FORMS: A form is a database object that you can use to enter, edit, or display data from a table or a
query.
REPORTS: A database report is the formatted result of database queries and contains useful data for
decision-making and analysis.
15. MS Access - Create Tables
Table Design View
1.We will be creating the following fields in this table.
These tables will store some of the information for
various book projects.
Field Name Data Type
Project ID AutoNumber
ProjectName Short Text
ManagingEditor Short Text
Author Short Text
PStatus Short Text
Contracts Attachment
ProjectStart Date/Time
ProjectEnd Date/Time
Budget Currency
ProjectNotes Long Text
2.Go to the Create tab.
3.In the tables group, click on Table and
you can see this looks completely different
from the Datasheet View. In this view, you
can see the field name and data type side
by side. We now need to make ProjectID a
primary key for this table, so let us
select ProjectID and click on Primary
Key option in the ribbon.
16. Let us save this table and give this table a name.
Click Ok and you can now see what this table looks like
in the Datasheet View.
Let us click the datasheet view button on the top left
corner of the ribbon. If you ever want to make changes
to this table or any specific field, you don't always have
to go back to the Design View to change it. You can
also change it from the Datasheet View. Let us update
the PStatus field . Click Ok and you will see the
changes.
17. MS Access - Adding Data
Let us add some data into your tables by opening the
Access database we have created and Select
the Views → Datasheet View option in the ribbon and
add some data
Similarly, add some data in the second table as well as
shown in the following screenshoYou can now see that
inserting a new data and updating the existing data is
very simple in Datasheet View as working in
spreadsheet. But if you want to delete any data you
need to select the entire row first.
Now press the delete button. This will display the
confirmation message.
Click Yes and you will see that the selected record is
deleted now.
18. MS Access - Query Data
A query is a request for data results, and for action on data. You can use a query to answer a simple question, to
perform calculations, to combine data from different tables, or even to add, change, or delete table data.
create a simple query which will retrieve information
from tblEmployees table. Open the database and click
on the Create tab.
Click Query Design.
The query runs, and displays only data in those field
which is specified in the query.
In the Tables tab, on the Show Table dialog, double-click
the tblEmployees table and then Close the dialog box.In the
tblEmployees table, double-click all those fields which you want to see
as result of the query. Add these fields to the query design grid as
shown in the following screenshot
19. MS Access - Alternate Criteria
You can add alternate criteria in the following two ways −
•You can use the OR operator to combine two sets of criteria.
•You can also use the query design grid, but instead of specifying criteria on the same line, you will need to separate
it in multiple row
1. Let us look at a simple example of alternate criteria.
Open database and in the Create tab select Query
Design.
2. Double-click on all the field you want to see as query
result.Double-click on tblEmployee and close the Show
Table dialog box.
3. You can now see that alternate criterion is specified
in different rows of the LastName field. When you run
this query, you will see the employees whose last name
is either Pollard or Manning.
20. MS Access - Relating Data
Normalization:
Normalization is the process of organizing
data in a database.
This includes creating tables and
establishing relationships between those
tables according to rules designed both to
protect the data and to make the database
more flexible by eliminating redundancy
and inconsistent dependency.

Let us now look into the following table which contains data, but the problem is that this data is quite
redundant which increases the chances of typo and inconsistent phrasing during data entry.To solve
this problem, we need to restructure our data and break it down into multiple tables to eliminate some of
those redundancy as shown in the following three tables.
22. Defining Relationships: A relationship works by matching data in key columns usually
columns with the same name in both the tables. In most cases, the relationship matches the primary key from one
table, which provides a unique identifier for each row, with an entry in the foreign key in the other table. There are
three types of relationships between tables. The type of relationship that is created depends on how the related
columns are defined.
One-to-Many Relationships
A one-to-many relationship is the most common type of relationship. In this type of relationship, a
row in table A can have many matching rows in table B, but a row in table B can have only one
matching row in table A.
For example, the Customers and Orders tables have a one-to-many relationship: each customer
can place many orders, but each order comes from only one customer.
Many-to-Many Relationships
In a many-to-many relationship, a row in table A can have many matching rows in table B, and vice
versa.
For example, the Customers table and the Cookies table have a many-to-many relationship that is
defined by a one-to-many relationship from each of these tables to the Orders table.
One-to-One Relationships
In a one-to-one relationship, a row in table A can have no more than one matching row in table B,
and vice versa. A one-to-one relationship is created if both the related columns are primary keys or
have unique constraints.
23. MS Access - Create Relationships
MS Access uses table relationships to join tables when you need to use them in a database object. There are
several reasons why you should create table relationships before you create other database objects, such as
forms, queries, and reports.
Click on the Save icon as in the above screenshot
Enter tblHRData as table name and click Ok.
Let us now add another table into your database and
name it tblHRData using Table Design
24. MS Access - Create Form
open your Database and go to the Create tab. In the
Forms group, in the upper right-hand corner you will
see the Form Wizard button.
Click on that button to launch the Form Wizard.
On this first screen in the wizard, you can select fields
that you want to display on your form, and you can
choose from fields from more than one table or a query.
Let us assume we want to simply have a quick form
that we are going to use for data entry for our employee
information.
From Tables/Queries drop-down list,
select tblEmployees table. Click on the double arrow to
move all the fields at once. Let us just leave it with that
one table, and click Next.
The following screen in the Form Wizard will ask for the
layout that we would like for our form. We
have columnar, tabular, datasheet and justified layouts.
We will choose the columnar layout here and then
click Next.
25. In the following screen, we need to give a title for our
form. Let us call it frmEmployees.
Once you have given your form a title, you can open
the form to see what that form looks like, or you can
begin entering information into your table. Or you can
choose the option to modify the form's design. Let us
choose the first option to open the form to view or enter
information and click Finish.
This is what your form looks like. This is a single item
form, meaning one record is displayed at a time and
further down you can see the navigation buttons, which
is telling us that this is displaying the record 1 of 9. If
you click on that button then, it will move to the next
record.
If you want to jump to the very last record in that form or
that table, you can use the button right beside that right
arrow, the arrow with a line after it, that's the last record
button. If you want to add new employee information,
go to the end of this records and then after 9 records
you will see a blank form where you can begin entering
out the new employee's information.
26. Multiple Item Form
You may also want to create a specific kind of form. For this, you
can click on the More Forms drop-down menu.
From the menu, you can create a Multiple Items form,
a Datasheet form, a Split form, or even a Modal
Dialog form. These are typically bound forms; select the
object that you would like to be bound to that form. This
does not apply to the Modal Dialog forms.
To create this type of form, you will need to select the
object in navigation pane first. Let us
select tblEmployees here.
Proceed by clicking on More Forms and Multiple Items.
Split Form
This type of form is divided in equal halves, either
vertically or horizontally. One half displays a single item
or record, and the other half displays a list or a
datasheet view of multiple records from the underlying
data source.
Let us now select tblEmployees in the navigation pane
and then on Create tab. Select Split Form option from
More Forms menu and you will see the following form in
which the form is divided vertically.
27. MS Access - Data Import & Data Export
Data import Start Microsoft Access and create a blank database in
Access. Import the Person/Org information. Go to the "External
Data" menu and select "Text File" in the Import Section. ... Select
the option to "Import the source data into a new table in the
current database" and click "OK.“
Data export is actually the opposite of importing data. In importing
data, we bring data from other formats in Access, while in
exporting we save the data in other formats. To understand what
kind of data you can export from Access data, let us open your
database and go to the External Data tab.
