Chapter 5 Outline
In our
day-to-day lives, we keep track of every single we do. From waking up to lying
in bed after a long day, there isn’t a day where our days aren’t eventful and
full of tasks and responsibilities. We set an schedule/planner – we keep track
of what we have do and check off each one after completion. This is very
reminiscent of a database, a track of things that mostly are done on
spreadsheets. The spreadsheets are grouped into columns, fields, rows, and
finally records. They are recorded on table or file and then sorted out
accordingly by specific elements. All of this information compiled makes up a
database: Tables or Files, the relationship among rows in tables, and the
metadata, data that describes data. For example, a company can maintain a list
of all of its employees as well as keep track of their workload, productivity, and
efficiency. All of this is to ensure that everything is in order because
without a track of things to keep an eye on, there’s no organization.
Any
database is made from a database management system (or abbreviated as DBMS).
This program allows people to create, process, and administer databases. The
companies and businesses then license DBMS products from vendors from IBM to
Microsoft to Oracle. The developers of Databases use DBMS to create tables,
relationships, and structures and afterwards, begin to process the database,
which requires four processing operations: Red, Insert, Modify, and Deletion.
All of the operations require us, the users, to input new database changes
whenever need be. Another function to take note of is the administration
aspect. Administration requires the setup of many security systems such as
accounts, passwords, permissions, and limits for processing the database
itself. Much like a computer, there are a lot components that go into the
system that require a lot of attention to detail. From its applications to the
browsers, computers now have paved way for information to be easily processed.
Our SJSU Library Database is a perfect example – it’s open to the students and
to the public with the accessibility of acquiring resources pertaining to a
large network of information. The Library itself is a structure while its
online system could be considered the database for which all the information is
based on.
However,
the database tables alone aren’t sufficient. If it the information presented
isn’t accurate, relevant, or even useful to right now, then it isn’t enough to
be considered legitimate. This is where a database application comes in – It is
a collection of forms, reports, queries, and application programs that serve as
an intermediary between users and the data from the database. The Database administration tasks are split
into 4 categories (DBA tasks): Development, Operation, Backup and Recovery, and
Adaptation. Each of these 4 has a set of tasks it completed while also having a
description that explains their purpose. Developmental tasks include creating
and staffing the DBA, form steering committee, specify requirements, validate
data models, and evaluate the design of the application. Operational tasks
include managing processing rights and responsibilities, manage security, track
problems and manage resolutions, monitor the database performances, and
managing DBMS. Backup and Recovery’s tasks include monitoring backup
procedures, conduct training, and manage recovery. Lastly, Adaptation’s role is
to set up a request tracking system and manage configuration changes.
The
applications have 4 elements: Forms, Reports, Queries, and Application
Programs. Forms allows user to view data, updating existing data, and delete
existing date. Reports are a structured presentation of data using sorting,
grouping, filtering, and other operations. Queries allow users to search based
on values. Lastly, application programs provided security, data consistency,
and with the purpose of special processing. They came into popularity around
the 90s and were, at the time, innovative through its technology. Nowadays, the
database applications are evolving thanks technology improving each and every
year. The database applications that make up the forms, reports, queries, and
application programs go through an organizational network that make up the
Database Management System (DBMS) and then Tables, relationships, and the
metadata.
Much like a
planer/tracker, the list of items/things to complete are neatly organized so
that each role serves some sort of purpose. The processes that go into it are
integrated and blended together to make up a database. The structure alone is
what forms the entire base of operations – the tasks given are a representation
of a list of items that are categorized by a specific element to give it
detail. Each of these inputs then spread out and given depth in nature. There
are entities and relationship that exist to help show how the data/tasks are interconnected
and how they entail organization within the database.
