VI. Selecting a Data Management System
Storing and Retrieving Data
When an application program request data
 from DBMS, the application program
 follows a logical access path

When the DBMS goes to a storage device
 to retrieve the requested data, it follows a
 path to the physical location (physical
 access path) where the data is stored
Logical and Physical Access Paths
Manipulating Data and
           Generating Reports
 Data manipulation language (DML): the
  commands that are used to manipulate the data
  in a database
 Structured Query Language (SQL): adopted by the
  American National Standards Institute (ANSI) as the
  standard query language for relational databases

Once a database has been set up and loaded
 with data, it can produce reports, documents,
 and other outputs
Database Administration
 DBA
  Works with users to decide the content of the database

 Works with programmers as they build applications
  to ensure that their programs comply with database
  management system standards and conventions

 Data administrator:
  Responsible for defining and implementing
   consistent principles for a variety of data issues
Popular Database Management
                   Systems
Popular DBMSs for end users include
 Microsoft’s Access and Corel’s Paradox
 The complete database management software market
  includes databases by IBM, Oracle, and Microsoft
Examples of open-source database systems:
 PostgreSQL and MySQL
Many traditional database programs are now
 available on open-source operating systems
Special-Purpose Database Systems
Some specialized database packges are used .
 for specific purposes or in specific industries:

 Rex-book from Urbanspoon
Morphbank(www.morphbank.net):
 Allows researchers to continually update and expand a
 library of more than 96.000 biological images
Selecting a Database Management
            System (continued)
Important characteristics of databases to
 consider
   Database size
   Database Cost
   Database users
   Performance
   Integration
   Vendor
