Runtime Environment

Runtime Environment is the foundation of software applications and provides the basic functionality required to run an enterprise application
The Runtime Environment of the eGovernment Standard Framework is composed of 8 service layers and provides 39 services. Refer to the following figure for the details.

Runtime Environment

Business Logic Layer

The business logic layer provides various functions such as business logic flow control, transaction management, error processing for application programs.

• Process Control

  This service supports the separation between business logic and business logic flow and executes predefined business logic processes. The business logic flow can be defined by external XML files.

• Exception Handling

  This service provides standard procedures for runtime exception handling.

Batch Layer

Batch processing services for setting up and running the batch data processing capabilities.

• Job Configuration

  Provides functions for Batch Job Configuration.

• Step Configuration

  Provides functions for Batch Step Configuration.

• ItemReader/ItemWriter

  Provides the File / DB processing functions according to the type of resource.

• Job Execution

  Provides functions for the ability to perform in the Job Instance.

• Step Execution

  Provides functions for the ability to perform in the Step Instance.

• Tasklet

  Provides functions for the processing of other simple batch job processing tasks required in the execution of the Job (moving files, etc).

• Job Repository

  Provides functions for the ability to store information JobExecution and StepExecution.

• Job Runner

  Provides functions for the interface that supports Scheduler, CommandLine(CronTab), HTTP / WebServices.

• Job Launcher

  Provides functions for running Jobs

• History Management

  Provides functions for History management capabilities using JobRepository

• Scalability

  Provides functions for MultiProcessing and Partitioning.

• Sync / Async Processing

  Provides functions for synchronous / asynchronous processing capabilities using JobLauncher settings.

• Parallel Processing

  Provides functions for the parallel processing capabilities using Step settings.

• Pre/Post Processing

  Provides functions for the pre-processing and post-processing Event Handling using Listener.

• Skip/Repeat/Retry

  Provides functions for Skip, Repeat, Retry feature.

Common Foundation Layer

Common Foundation Layer provides commonly used functions for runtime environment services.

• AOP

  Implements and supports ASP(Aspect Oriented Programming).

• Cache

  Provides caching functions for instant access to frequently used contents to minimize access overhead or time.

• Compress/Decompress

  Provides data compression and decompression functions for storing or transmitting data efficiently.

• Encryption/Decryption

  Provides data encryption and decryption functions for secure data transmission.

• Excel

  Provides a Java library for handling Microsoft Excel files.

• File Handling

  Provides file handling functions such as file generation, file access, file update, etc.

• File Upload/Download

  This service, mainly used in the presentation layer, provides file upload and download functions.

• FTP

  Provides FTP(File Transfer Protocol) client functions for transmitting and receiving data via FTP protocol.

• ID Generation

  Provides system ID(Identifier) generation function conformant to the UUID(Universal Unique Identifier) standard.

• IoC Container

  Provides the IoC(Inversion of Control) function, one of the basic functions of the framework.

• Logging

  Provides log recording and controlling functions via a simple configuration to minimize the overhead due to casually used System.out.println statements.

• Mail

  Provides SMTP(Simple Mail Transfer Protocol) client functions for transmitting and receiving emails.

• Marshalling/Unmarshalling

  Provides marshalling and unmarshalling functions which convert specific data types into objects or vice versa.

• Object Pooling

  Provides available object(s) to application programs when there is(are) available object(s). If no available object(s), this service generate and allocate the object(s) according to the predefined pool size.

• Property

  Keeps key-value tuples of external files or environment information and provides the access to these tuples for application programs when needed.

• Resource

  This service, for Internalization and Localization, provides functions for retrieving appropriate messages in the desired locale using key-value pairs.

• Scheduling

  Supports periodically or repeatedly executed jobs in the application server, similar to the Cron command in UNIX.

• Server Security

  Provides user authentication and rights management functions for secure server function call or data access.

• String Util

  Provides various functions for handling string data.

• XML Manipulation

  Provides various functions for generating, parsing and writing XML data.

Mobile Device API Layer

Mobile Device API Layer provides 12 fundamental device APIs and Hybrid App templates which are based on Open Source(PhoneGap)

• Accelerator

  provides the captures of device motion in the x,y, and z direction

• GPS

  provides the geolocation objects to access the location data based on the device's GPS sensor or inferred from network signals

• Vibrate

  provides the devices to vibrate for specified amount of time

• Camera

  provides access to the device's default camera application

• Contact

  provides access to the device contacts database

• Compass

  Obtains the direction that the device is pointing

• File Reader/Writer

  provides to read, write and navigate file system hierarchies, based on the W3C file API

• Network

  provides information about the device's cellular and wifi connection

• Device

  provides information about the device's hardware and software

• Media

  provides the ability to record and play back audio files on a device

• Interface

  provides the connectability to the web-server which built based on the eGovframework
