MTTK Lowcode Engine and MTTK Open BI

中文说明

Brief

MTTK Open BI

A user-friendly lightweight BI tool.

It is a set of plugins of MTTK Lowcode Engine, so the user manual and develop manual are combined together with MTTK Low Code Engine.

• Lightweight
  No data processing engine offered, all the data processing depends on the target Databse Server.

• Easy to use
  For example ,to build an echart need to provide many many configurtaions/options, such as title location, grid position,etc. To simplified the usage ,only the important options should be configured by user with default setting, other options are set by BI system automatically.

MTTK Lowcode Engine

A platform for rapid development of HTML5 applications without or with a small amount of code.

Most of the Lowcode are form generation + workflow, so it can only develop some simple project such as leave application,survey. Our design concept is quite different as described below.

• Vue3 based
  It can be considered as a visual Vue3 editor to manipulate data/computed/method/component properties/etc. So it can do the same thing as what Vue3 can do.
• Pluggable
  It is NOT a good idea to use lowcode to build a project with many customized code,but using low code for specific scenarios is valuable. So how to make lowcode to fit the specific scenario? The answer is plugin.MTTK Open BI is a good sample of what plugin can do. First the component libarary can be extended, Second the login page/application resource/property editor/etc. can also be extended by plugin mechanism.

Please DO NOT CHANGE THE PASSWORD and the data will be reset every day. And since the server performance is pool it is a little slow to access especially the first time since some JS should be download.
