In information technology, architecture plays a major role in the aspects of business modernization, IT transformation, software development, as well as other major initiatives within the enterprise. IT architecture is used to implement an efficient, flexible, and high quality technology solution for a business problem, and is classified into three different categories: enterprise architecture, solution architecture and system architecture. Each of these classifications varies in their implementation and design, depending on the contextual business scope, organization structure, and corporate culture.
Architecture Level
Architecture level represents the scope boundary and granularity of details the architectural activity should take, based on organization hierarchy and communication audience.
- Enterprise Architecture (Company level) aligns technological strategies and execution plans with business visions and objectives by providing architectural oversight and guidance. Enterprise architecture also drives consolidation, reuse, and economy of scale by addressing company-wide goals in a holistic way across all IT projects.
-
Solution Architecture (Department level) models a solution vision that defines the IT systems, business processes and reusable services for a specific business unit, spanning across business and technology architectures.
-
System Architecture (Team level) defines the structure of an information system in terms of various subsystem components and their relationships with internal and external systems. System architecture focuses on application, data, and technology, and is called software architecture in some organizations.
Before making decision regarding system architecture the designer must consider the following points:
- Corporate organization and culture: System architecture must study day-to-day functions of business and users in order to understand corporate organization and culture. This will help in focusing on operational feasibility which will help in deciding other checklist items.
- Enterprise resource planning (ERP): Most of the organization use ERP software these days and it is important for the analyst to understand the compatibility of the ERP which is used to the proposed system.
- Total cost of ownership (TCO): System analyst must try to get solutions of different questions which helps in finding initial cost and cost which may add up during the development, which is total cost of ownership. This is most important at this will determine total cost and budget of system.
- Scalability: Determining system ability to expand or downsize according to business requirements.
- Security: What security system and policy needs to be implemented.

Answer:
Explanation: search engine uses system algorithm to search out items or information as required by the user. Example is google, chrome.
Data base are archives where information could be retrieve. Its contain information such as publications, abstract,journals.
Search engine provides wide range of information depending on you request while database are mostly for academics related materials.
Data base- A good place to generate this information is library, archivals while journal, publiications are kept while search engine can be used anywhere you have an internet facilities.
In a data base, information is searched in an organized way. The collections are already well arranged in different cubicle search engine provides wide range of information not organized.
Data base may contain more complex information not easily understood, search engine provides more elaborate answers.
Similarity of the two is that they both provide information.
They are both reliable.
School library is an example of where journals and publication are kept and can be retrived.
