1. At the end of the lesson, the students must be able to: Comprehend the fundamental concepts and principles of system architecture and integration. Analyze various integration styles and architectural pattern. Evaluate the pros and cons of integrating systems using web services, API’S, and ,message- oriented middleware. In resolving integration challenges, exhibit Critical thinking and problem splving skills. Effectively Communicate integration concepts and solutions through written reports and oral presentation. INTRODUCTION TO SYSTEM INTEGRATION AND ARCHITECTURE

2. What is IT Integration?

3. IT integration, also known as system integration, refers to the process of connecting data, applications, application programming interfaces (APIs), and devices throughout an entire IT organization to increase efficiency, productivity, and agility. Integration does not only link, but it also provides value by providing new features that are made possible by connecting the functions of multiple separate systems

4. Restaurant Management System

5. Components: Point of Sale (POS) System: Manages customer orders and payments. Inventory System: Tracks ingredients and stock levels. Accounting Software: Manages finances and reports.

6. Integration Steps: Connecting the POS System to the Inventory System: When an order is placed in the POS, it automatically deducts the used ingredients from the inventory system. 2. Linking the Inventory System to the Accounting Software: When stock levels are updated in the inventory system (e.g., after a delivery), it automatically updates the expenses in the accounting software. 3. Data Reporting: Use a reporting tool to pull data from both the POS and accounting software, allowing the restaurant owner to see sales performance and profits in one dashboard.

7. Benefits: Efficiency: Reduces manual entry, saving time and minimizing errors. Real-Time Data: Provides up-to-date information on stock levels and sales. Simplified Reporting: Streamlines financial reporting by integrating sales and expenses.

8. System Integration and Architecture An architectural model of a system is known as a system architecture, and it is responsible for defining the system’s behavior in addition to its structure.

9. Architectural Model: Restaurant Management System Components and Interactions: 1. Point of Sale (POS) System Function: Manages customer orders and payments. Interaction: Sends order details to the Inventory System. Communicates with Accounting Software for sales reporting. 2. Inventory System Function: Tracks ingredients and stock levels. Interactions: Receives order updates from the POS to deduct used ingredients. Sends stock level updates to the Accounting Software. Provides inventory data to reporting tools.

10. 1. Accounting Software Function: Manages finances and generates reports. Interactions: Receives updates from the Inventory System for expenses. Pulls data from the POS for sales figures. Generates financial reports and dashboards. 1. Reporting Tool Function: Aggregates data for analysis and reporting. Interactions: Pulls data from both the POS and Accounting Software to provide insights into sales performance and profits.

12. Definition and Importance of System Integration and Architecture The Systems Integration Architecture e stablishes a connection between disparate operational applications and platforms. Electronic commerce is supported by the integration of business applications between agencies and vendors or other agencies. System integration is the process of combining various subsytems components,or applications into a single, functional system. It involves integrating software, hardware,networks, and data to facilitate communication, data exchange, and interoperability between diverse systems In contrast, system architecture refers to the design and structure of a system at a high level. It describes the arrangement and organization of the system’s components, their relationships,and how they interact to attain the system’s goals. System architecture provides a blueprint for effectively constructing and integrating systems.

13. What is System Integration?

14. Software Integration It is the process of combining all virtual and physical components into a single cohesive infrastructure to ensure that all of an organization’s parts function as a whole. Virtual components consists of all the computer hardware modules. System integration is also known as a software integration and information technology.

15. What purpose does system integration serve? Why is system integration is essential? Businesses implement system integration primarily to ensure that all systems operate in unison to increase productivity and improve the quality of day-today operations. The purpose of system integration is to streamline and facilitate communication not only between an organization’s internal systems but also with its external partners. System Integration expedites the flow of information and reduces operational expenses.

16. Various Sytem Integration Types Integration of legacy system technology -this method enables the modernization of legacy systems by facilitating a seamless communication channel with more recent technological soutions and information systems. Enterprise application integration (EAI) -integrates diverse subsytems into a unified business environment and facilitates the exchange data between applications in real-time. Data integration -enables you to collect data from various services,aggregate and transform it, amd make it accessibke from a central location to facilitate interactive reporting. Enterprise-to-enterprise integration - is the automation of inter-organozational business communications and processes. Electronic Document Exchange(EDI) - is the exchange of standardized business documents between companies. It can also be defined as the standard electronic format that business use to supplant paper-based documents such as invoices and purchase orders.

17. Methods of Sytem Integration Integration between specific nodes -integrations in this form are typically employed to manage a single business function and do not involve complex business logic. Star amalgamation- also known as the spaghetti method,this form of integration enables enhanced functionality. Integrated hub and spoke structure - system is directly connected to a central hub that mediates request and decouples data receivers and and senders. Vertical integration - it is a relatively straightforward and uncomplicated approach involving a small number of sytems. Horizontal integration - in contrast to vertical integration ot facilitates communication between subsystems. Common data format integration - this form of integration eliminates system to contain multiple adapters for each subsystem.

18. What is a system integrator’s functions? system integrators specializes in bridging internal and external applications, systems, cloudbased software solutions, and data storage. A system integrator’s objective is to combine multiple subsytems into a singular integrated solution and ensure that they operate in tandem

19. Stages involed in system integration Detrmine requirement s- determine your expectations for the integrated systems and communicate them to the system integrator as the initial phase in system integration. Analyze feasibility - after defining the requirements for your future software, you must conduct a thorough analysis to determine it it is operationally feasible. Architect design - develops a strategy to integrate the numerous components into a single,functionally unified system. Develop the management plan - develop integration schedule, identify alternate options, and calculate potential risks. System integration design - executes the actual system integration in accordance with the architectural design,ensuring that no data lost. Implementation - it ensures that the integrated system is error free. Maintenance - responsible for performing scheduled diagnostics to detect new errors and notify the IT team of any issues.
