EasyQuery.JS is a platform independent solution that lets you embedding ad-hoc reporting or advanced search functionality to your web application.
It gives you a simple to use but powerful user interface to build a query or a filter to your data. Your end-users will get the power of SQL, even if they can't pronounce it properly. All the complexity is hidden from the end-user - just simple to use and easy to learn UI.
Doesn't matter what server-side platform/language you use - either Java, PHP, NodeJS or something else. EasyQuery.JS covers them all, requiring a minimum additional code to get things worked.
You will find more details about EasyQuery on the EasyQuery page.
Visit also the end-user's guide to get an idea what the EasyQuery UI is.
EasyQuery UI is implemented as set of JQuery Widgets that are embedded to your html page(s).
On the server-side your application needs some code to be added to support EasyQuery requests. We provide code samples for some platforms in the package. Also there are step-by-step descriptions how to make that samples worked.
Usually this code is just a proxy to pass the requests to EasyQuery Server or to execute the SQL query over your database.
EasyQuery.JS requires a special web-service that is able to generate SQL query using the query created by your customer via EasyQuery UI and the data model. We call it EasyQuery Server.
There is public EasyQuery Server that you can use with your application. As an alternative, you can install EasyQuery Server on-premises on your own server.
EasyQuery UI (embedded to some html page) requests the data model from your server-side application using AJAX request.
The data model defines which entities and attributes your users can operate with when they build their queries. It allows to set user-friendly names for tables (entities), fields (attributes) and operators (like “is equal to” or “starts with”). Additionally data model can contain a list of predefined values for some attribute - so your users will be able to select a criteria parameter from some list instead of typing it.
.NET version of EasyQuery allows you to build data model at run-time. On other platforms, you will need to create data model “manually” using either our eqdm command line utility (runs on Windows, Linux and Mac) or Data Model Editor (DME) GUI application (only for Windows). These tools are available to you as part of EasyQuery.JS.
A simple application usually has only one database to work with and, respectively, only one data model. In this case an application just returns that data model in the response.
However, sometimes you need to use different models/databases in the same application, or just want to organize all the models in the single place. EasyQuery Server is able to store your data models and lets you request them by ID. In such a case the application will request the model from EasyQuery Server before returning it to frontend.
End-user adds some columns and conditions to the query using EasyQuery UI.
At some moment EasyQuery UI needs to inform the application that the query has changed. It could be done automatically on every end-user's action, or we can wait until end-user pressed some "refresh" button. Anyway, at this point EasyQuery UI sends the JSON representation of the query created to your application.
The application actually doesn't need the proprietary JSON query. Usually it needs some SQL query to be able to query the database. So the application passes the JSON query to the EasyQuery Server in order to get the SQL query built for the specific database.
EasyQuery Server returns the generated SQL query to the application.
Now the application is able to connect to the database and to run the SQL query on it.
The application receives the result of SQL query execution. Usually it gets some tabular data.
The (pre-formatted by the application) result tabular data are sent to the frontend to be visualized. EasyQuery UI has some built-in tools to visualize the result via grid or chart. But it's absolutely up to you how to process and visualize the result data on frontend.
The very important part of EasyQuery is the component that generates a correct SQL for the specific database on the base of end-user-created query.
This part is developed as .NET component. So the users of .NET editions of EasyQuery have this part integrated to the application itself.
For all others we provide public EasyQuery Server as SAAS.
This service implements a REST API which allows you to pass your query JSON string and get a correct SQL statement in the result. You are also able to store and load your data models using the service.
The public EasyQuery Server is mostly aimed to support the Community-license customers. But even if you purchased the Company license and got access to the on-premises server, you are still able to use the public EasyQuery Server as well.
Sometimes using SAAS is not an option. It could be the corporate limitations, strict security policies or you just need to build an intranet application without internet access.
For such cases we provide EasyQuery Server on-premises - the server software that could be installed on your own hardware and configured to work with EasyQuery UI.
This option is only available for Company license owners.
EasyQuery Server on-premises is built as .NET Core application, so it can be set up on any platform that .NET Core 2 can be installed on. The detailed instructions on how to setup EasyQuery Server is included to the package.
