ASSINGNMENT QUESTIONS

* 1. Identify the various types of users/customers of an HRIS. * 2. What are the three broad categories of data that an HRIS manages? * 3. How does network bandwidth affect a 2-tier client server architecture? * 4. How does an N-tier architecture simplify IT departments’ task of maintaining client software?

ANSWERS

1) Individuals who will be using the HRIS can be split into two general groups: employees and nonemployees. The employee category includes.

* Managers who rely on the HRIS and the data analyzed by the analyst/power user to make decisions;

* Analyst/power users who use the HRIS to evaluate potential decision choices and opportunities;

* Technical staff who are responsible for providing a system that is usable and up-to- date for each user and clerical employees who largely engage in data entry; and

* Employees who use the HRIS on a self-service basis to obtain personal information, for example, to look up paycheck information, to make choices about benefits during open enrollment, or to see how much vacation time they have available.

2) What these users all have in common is that all the information is about potential and current employees with a focus on managing the organization’s human capital to achieve strategic organizational goals. Specific data from the HRIS database fit into three categories:

* Information about people, such as biographical information and competencies (knowledge, skills, abilities, and other factors)

* Information about the organization, such as jobs, positions, job specifications, organizational structure, compensation, employee/labor relations, and legally required data

* Data that are created as a result of the interaction of the first two categories, for example, individual job history, performance appraisals, and compensation information

3) HOW DOES A NETWORK BANDWIDTH AFFECT A 2-TIER CLIENT SERVER ARCHITECTURE;

During the 1980s, it was discovered that many typical HR functions (such as employee benefits and recruiting) did not require the high-powered and expensive processing available on the mainframe computers.
With the advent of the personal computer (PC), many of these functions could be reallocated to the local processing power of the PC.
By the end of the decade, HRIS software vendors such as PeopleSoft began using this power of PCs and created the client-server architecture

THE PURPOSE OFCLIENR SERVER
The purpose of client-server architecture was to spread out low-powered processing capability to the dozens of PCs now being used across an organization.
High-performance applications such as Payroll would still be run in a batch process on the mainframe computer or outsourced to vendors such as Automated Data Processing (ADP).
But day-to-day processing could be implemented on the PC.

4) N-TIER ARCHITECTURE
N-Tier architecture is an industry-proved software architecture model, suitable to support enterprise-level client/server applications by resolving issues like scalability, security, fault tolerance and etc. NET has many tools and features, but. NET doesn’t have pre-defined ways to guard how to implement N-Tier architecture. Therefore, in order to achieve good design and implementation of N-Tier architecture in. NET, understanding fully its concepts is very important. However, many of us may hear, read or use N-Tier architecture for many years but still misunderstand its concepts more or less. This article tries to clarify many basic concepts in N-Tier architecture from all aspects, and also provide some practical tips. The tips in this article are based on the assumption that a team has a full control over all layers of the N-Tier architecture.
