Project manager
Project management is a people who process and activity of
planning, organizing, motivating, and controlling resources to achieve specific
goals. A project is a temporary endeavor designed to produce a unique product,
service or result with a defined beginning
and end.
Database Admin
Database administrators (DBAs) are primarily responsible for
specific databases in the subsystem. In some companies, DBAs are given the
special group authorization, SYSADM, which gives them the ability to do almost
everything in the DB2® subsystem, and gives them jurisdiction over all the
databases in the subsystem. In other shops, a DBA's authority is limited to
individual databases.
The DBA creates the hierarchy of data objects, beginning
with the database, then table spaces, tables, and any indexes or views that are
required. This person also sets up the referential integrity definitions and
any necessary constraints.
The DBA essentially implements the physical database design.
Part of this involves having to do space calculations and determining how large
to make the physical data sets for the table spaces and index spaces, and
assigning storage groups (also called stogroups).
Many tools are available to help DBAs perform their tasks.
The DBA can be responsible for granting authorizations to
the database objects, although sometimes there is a special security
administration group that does this.
The centralization of data and control of access to this
data is inherent to a database management system. One of the advantages of this
centralization is the availability of consistent data to more than one
application. As a consequence, this dictates tighter control of that data and
its usage.
Responsibility for an accurate implementation of control
lies with the DBA. Indeed, to gain the full benefits of using a centralized
database, you must have a central point of control for it. Because the actual
implementation of the DBA function is dependent on a company's organization, we
limit ourselves to a discussion of the roles and responsibilities of a DBA. The
group fulfilling the DBA role will need experience in both application and
systems programming.
In a typical installation, the DBA is responsible for:
Providing the standards for, and the administration of,
databases and their use
Guiding, reviewing, and approving the design of new
databases
Determining the rules of access to the data and monitoring
its security
Ensuring database integrity and availability, and monitoring
the necessary activities for reorganization backup and recovery
Approving the operation of new programs with existing
production databases, based on results of testing with test data.
In general, the DBA is responsible for the maintenance of
current information about the data in the database. Initially, this responsibility
might be carried out using a manual approach. But it can be expected to grow to
a scope and complexity sufficient to justify, or necessitate, the use of a data
dictionary program.
The DBA is not responsible for the actual content of
databases. This is the responsibility of the user. Rather, the DBA enforces
procedures for accurate, complete, and timely update of the databases.

Web Designer
Web design encompasses many different skills and disciplines
in the production and maintenance of websites. The different areas of web
design include web graphic design; interface design; authoring, including
standardised code and proprietary software; user experience design; and search
engine optimization. Often many individuals will work in teams covering
different aspects of the design process, although some designers will cover
them all.[1] The term web design is normally used to describe the design
process relating to the front-end (client side) design of a website including
writing mark up. Web design partially overlaps web engineering in the broader
scope of web development. Web designers are expected to have an awareness of
usability and if their role involves creating mark up then they are also
expected to be up to date with web accessibility guidelines.
