Responsibilities of the Network Administrator (System Administration Guide, Volume 3) As a network administrator, your tasks generally fall into the following areas: Designing and planning the network Setting up the network Maintaining the network Expanding the network Each task area corresponds to a phase in the continuing life cycle of a network. Designing the Network The first phase in the life cycle of a network involves creating its design, a task not usually performed by new network administrators. Chapter 5, Planning Your TCP/IP Network describes the factors involved in network design. Setting Up the Network After the new network is designed, the second phase of network administration begins, which involves setting up and configuring the network. The tasks involved in this phase are a major responsibility for network administrators. Chapter 6, TCP/IP Administration contains instructions for the tasks involved in this phase of the network life cycle. Maintaining the Network "Configuring Network Clients" explains how to set up new hosts on an existing network. Note -

By declaring the field datatype in the above method, the datatype of the column is dynamically applied to the field. This method is useful when you are altering the column specification of the table, because you do not need to change the code again. NOTE: You can use also %type to declare variables and constants. The General Syntax to declare a record of a uer-defined datatype is: The following code shows how to declare a record called employee_rec based on a user-defined type. If all the fields of a record are based on the columns of a table, we can declare the record as follows: For example, the above declaration of employee_rec can as follows: The advantages of declaring the record as a ROWTYPE are: 1) You do not need to explicitly declare variables for all the columns in a table. 2) If you alter the column specification in the database table, you do not need to update the code.

Software Development Methodologies A software development methodology or system development methodology in software engineering is a framework that is used to structure, plan, and control the process of developing an information system. There are the following methodologies: Agile Software Development Crystal MethodsDynamic Systems Development Model (DSDM)Extreme Programming (XP)Feature Driven Development (FDD)Joint Application Development (JAD)Lean Development (LD)Rapid Application Development (RAD)Rational Unified Process (RUP)ScrumSpiralSystems Development Life Cycle (SDLC)Waterfall (a.k.a. Traditional) Agile software development is a conceptual framework for undertaking software engineering projects. Most agile methods attempt to minimize risk by developing software in short timeboxes, called iterations, which typically last one to four weeks. Agile methods emphasize realtime communication, preferably face-to-face, over written documents. Alistair Cockburn developed the Crystal Methods approach. XP Core Practices 1. 2.
Oracle/PLSQL Oracle is a relational database technology developed by Oracle. PLSQL stands for "Procedural Language extensions to SQL", and is an extension of SQL that is used in Oracle.
