项目描述
We only consider individuals to perform work (including: IP. After the start of the work and assessment of their quality, we are ready to make an offer for long-term regular cooperation.
Accommodation of the performer - Moscow or Moscow region.
To make a decision on cooperation, it will be necessary to demonstrate experience in implementing the requirements specified in the project description. Best of all, in the example of projects made or in a demo environment.
The task is to finalize the application implemented on Lazarus (an analogue of Delphi) PostgreSQL. The app is currently 30% ready, there is TK. The option of upgrading to 100% readiness or creating from scratch on a web platform (Ruby on Rails, jQuery Python / PHP) is considered. But a new platform and/or developer must have ready-made components to implement the functionality of an enterprise database application:
1. display tables and views that may contain several million rows without significantly increasing the performance requirements of the client application
2. application of filters and sorting to displays (sorting and filtering should be performed on the database server or on the application server), saving the filter parameters, sorting, order and width of the display columns
3. Before the beginning of data editing, their blocking at the level of individual records must be performed. If it is found that at least one record is blocked, the program must provide information about which users are currently blocked.
4. functionality of simultaneous editing of several records at once. If a particular field contains different values in the records, then two options should be available for each field when editing it: replace its value in all records with the entered one or do not change the values.
5. in the case of a “thick” client, the functionality of checking updates and the installer, in the function of which includes including, should be provided. Update the already installed version of the fat client, and updated
