15. Introduction to Databases

16. Database
A database is made up of a collection of tables that stores a specific set
of structured data. A table contains a collection of rows, also referred to
as records or tuples, and columns, also referred to as attributes. Each
column in the table is designed to store a certain type of information,
for example, dates, names, amounts, and numbers.

17. Relational Data Model in DBMS

2 Khalil Amazon Active
3 Ahmad Microsoft Inactive
4 Rizwan Amazon Active
Column/Attribute/Field (Domain)

/Tuple
(Record)

18. Methods of Data Storage
▪ Text File (CSV)
▪ Spreadsheet (MS Excel)
▪ Database Software (MS Access, Oracle, MS SQL Server, MySQL etc.)

19. SQL-Server Database
A computer can have one or more than one instance of SQL Server
installed. Each instance of SQL Server can contain one or many
databases. Within a database, there are one or many object ownership
groups called schemas. Within each schema there are database objects
such as tables, views, and stored procedures. Some objects such as
asymmetric keys are contained within the database, but are not
contained within a schema.
