DataArts Factory is a one-stop big data collaborative development platform that provides fully managed big data scheduling capabilities. It manages various big data services, making big data more accessible than ever before and helping you effortlessly build big data processing centers.

DataArts Factory used to be Data Lake Factory (DLF). Therefore, in this document, both Data Lake Factory and DLF can be used to refer to DataArts Factory.

Introduction to DataArts Factory

DataArts Factory enables a variety of operations such as data management, script development, job development, job scheduling, and monitoring, facilitating data analysis and processing.

Main Functions

**Table 1** Main functions of DataArts Factory
Function	Description
Data management	Manages multiple data warehouses, such as GaussDB(DWS), DLI and MRS Hive. Manages data tables using the GUI or data definition language (DDL).
Script development	Provides an online script editor that allows more than one operator to collaboratively develop and debug SQL, Python, and Shell scripts online. Allows use of variables and functions.
Job development	Provides a graphical designer that allows you to quickly build a data processing workflow by drag-and-drop. Presets multiple task types such as data integration, SQL, and Shell, and completes data analysis and processing by dependency between tasks. Supports job import and export.
Resource management	Supports unified management of file, jar, and archive resources used during script and job development.
Job scheduling	Schedules jobs to run once or recursively and use events to trigger scheduling jobs.
Monitoring	You can run, suspend, restore, or terminate a job. You can view the operation details of each job and each node in the job. You can use various methods to receive notifications when a job or task error occurs.

Objects in DataArts Factory

Data connection: A data collection is a collection of information required for accessing data storage (computing) space, including the connection type, name, and login information.
Solution: A solution provides users with convenient and systematic management operations to better meet service requirements and objectives. Each solution can contain one or more business-related jobs, and one job can be used by multiple solutions.

Job: A job is composed of one or more nodes that are performed collaboratively to complete data operations.
Script: A script is an extension of a batch processing file. It is a program that stores text. Generally, a computer script program is a combination of a series of operations that control computers to perform operations. In the script program, certain logic branches can be implemented.
Node: A node defines the operations performed on data.
Resource: Resources refer to self-defined codes or text files that are uploaded by users and scheduled when node tasks are executed.

Expression: Node parameter values in a node job can be dynamically generated based on the running environment by using Expression Language (EL). EL uses simple arithmetic and logic to calculate and reference embedded objects, including job objects and tool objects.

Environment variable: An environment variable is an object with a specific name in the operating system. It contains information to be used by one or more applications.
PatchData: PatchData refers to the instance that is generated in a period of time by a periodically scheduled job.
