Data Source
Provides functions for excluding dependencies between business logic processing and database connection methods by providing various database connection methods as well as an abstract layer about these methods.
ORM
Supports the development of business logic code not by SQL but by Object by providing the ORM(Object-Relational Mapping) function which is the mapping function between the object model and the database model.
Transaction
As a service for processing the database transaction, provides a consistent programming model by providing abstracted methods for the transaction processing.

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).
ORM
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.
Integration Layer

Integration layer supports communication and integration with other systems using standard interfaces.

Naming Service
Allows application programs to find remote modules or remote resources.
Web Service
Using this service, application programs or systems can export their business logic service to other applications or systems through Web Service standard interface.
Integration Service
This service, providing common interfaces with eGovernment system, provides standardized processing methods to cope with various integration methods of different solutions.
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.
