Study Notes
Integration of Software and Technologies
- Integration of software refers to techniques for combining existing software components to form a complete system.
- Integrative programming deals with integration approaches and techniques that connect different components of IT infrastructure to enable secure, intra and inter-application collaboration.
Types of Integration
- Application integration assists in the unlimited sharing of data and business processes among any connected applications or data sources without making major changes to the applications or data structures.
- System Integration is the process of combining two or more systems, subsystems, or components to function properly.
- Functional Integration is an inter-system communication where the integrated system provides new functionality or uses new technology while preserving original system functionality.
Integration Models
- The integration model defines how applications will be integrated by defining the nature of and mechanisms for integration.
- Presentation Integration Model integrates new software through the existing presentations of the legacy software.
- Data Integration Model integrates software through access to the data created, managed, and stored by the software.
Integration Methods
- Heterogeneous integration: each application implements its own data model, requiring mappings and transformations.
- File Transfer: one application writes a file that another application later reads, requiring agreement on filename, location, format, and timing.
- Shared Database: a single physical database shared by different applications running on different platforms.
- Remote Procedure Invocation: one application exposes its functionality to be accessed remotely by other applications.
- Middleware: software that connects applications or software components.
Networking
- Internet Protocol (IP) designed to allow multiple routes between any two points and to route packets of data around damaged routers.
- Transmission Control Protocol (TCP) is the backbone of HTTP/HTTPS protocol used to load web pages.
- Window: a field in TCP Packet Structure that refers to the amount of data that a sender can transmit before requiring an acknowledgment from the receiver.
- Time-to-Live: maintains a counter that gradually decrements down to zero, at which point the datagram is discarded.
- Header Checksum: ensures IP header integrity.
XML and HTML
- XML is used to separate data from presentation, focusing on what data is.
- HTML is used to display data, focusing on how data looks.
- XML Syntax Rules:
- XML documents must have a root element.
- XML prolog is optional.
- All XML tags should have a closing tag.
- XML tags are case-sensitive.
- XML elements must be properly nested.
- XML attribute values must be quoted.
- XML cannot contain white spaces.
XML Elements and Schemas
- XML element: everything from the element's start tag to the element's end tag.
- XML Schemas (XSD): used to validate XML documents, supporting data types and namespaces.
- XML validator: used to syntax-check XML documents.
- DTD: can be added to XML documents to define the structure and organization of the document.
HTML DOM and XMLHttpRequest
- HTML DOM defines a standard way for accessing and manipulating HTML documents.
- XMLHttpRequest object can be used to request data from a web server to update a web page by reloading the page.
Design Patterns and API
- Design Patterns: also called micro-architecture, described in the Gang of Four (GoF) book.
- API: sets of requirements that govern how one application can talk to another.
Abstract Classes and Version Control
- Abstract class: a class that contains one or more abstract methods.
- Version control: enables multiple people to simultaneously work on a single project, with features such as rolling back to previous versions and understanding bug reports.
Firebase Features
- Firebase provides features such as:
- Authentication
- Realtime Database
- Crashlytics
- Firebase Cloud Messaging
- Firebase Performance Monitoring
- Firebase Test Lab
