2. What is data?
By data, we mean known facts that can be
recorded and that have implicit meaning.
DATA
Sequence of symbols with interpretation

3. What is database?
A database is a collection of related data.
For example-student record
What is database system?
A system that manages the database.
Databases and database systems are an
essential component of everyday life in our
society.
Databases and database technology have a
major impact on the growing use of computer.

4. TRADITIONAL VS MODERN DATABASE
SYSTEMS
1) Problems with early database systems was the intermixing of
conceptual relationships with the physical storage & placement of
records on disk. For example-the grade records of student could be
physically stored next to student record. Although this was very efficient
access for queries and transactions, but it was not so flexible to access
records when new queries and transactions were identified.
Whereas new database applications can adapt to change easily. It may
be necessary to change the structure of a database as requirements
change. So it may be necessary to add a file to database or to extend
the data elements in an existing file. No stored data and existing
application programs are affected.

5. 2) RDBMS(Relational Database Management System) introduced
in the early 1980s were quite slow,since they did not use physical
storage pointers or record placements to access related data
records.
With the development of new storage and indexing techniques
and better query processing and optimization,their performance
improved.

6. 3) Traditionally, database technology applies to
structured and formatted data that arises in
routine applications in government,business and
industry.
But now with the advancement in technology and
in our needs ,we are not just satisfied with
numeric and string based simple data. We also
need books,scripts, and other forms of library
based articles. For this there has been a
concurrent development of a field called
INFORMATION RETRIEVAL(IR) that is
concerned with searching for material based on
keywords,and many problems dealing with
document and text processing and ranking them
based on relevance.

7. 4) In traditional database applications,most of the information is
stored and accessed in either textual or numeric form.
In past few years,advances in technology has led to new
applications of database systems. It is now possible to store
images,audio clips, and video streams digitally,i.e. multimedia
database.
For example-
Geographic Information Systems (GIS) use spatial applications
to store and analyze maps,weather data, and satellite images.
Scientific applications store large data from experiments.
News channels store large amount of multimedia data.
Storage of images like satellite photographs and images from
medical procedures such as X-rays and MRI(magnetic resonance
imaging).
