Experience
控股公司管理会计制度
The financial analyst of the holding was performing data entry by companies with a breakdown by projects, periods, 以及归属于成本和利润中心的费用项目.
The user interface for the data entry was developed using MS Access forms.
系统的后端是一个MS SQL数据库.
Reporting was developed using MS Excel connected to the database via the pivot-tables mechanism.
XLM数据集成框架
1. Loading the contents of XML files of various schemas into a single database table.
2. 将XML模式的XSD文件解析为表格格式.
3. Using table (2) information to create templates for mapping source data elements to the target database structure.
4. Applying templates (3) to loaded data (1) to automatically transform source XML files data into the target relational data structure.
The implemented system made it possible to set up the daily integration of open public procurement data (zakupki.gov.ru)，每天由数十个模式的数千个XML文件组成.
ITSM流程挖掘解决方案
解决方案包括:
1. 构建本地过程挖掘数据仓库(PostgreSQL), updated hourly from production assyst system (MS SQL) using incremental sync. 该同步是使用Pentaho DI开发的.
2. Applying transformations of source data into the process mining data model. The model contained all types of high-level ITSM tasks (incidents and change requests) and "child" tasks and decision tasks for each instance. 转换是使用pgSQL开发的. The model included many additional attributes and measures obtained from the source data and calculated on the fly.
3. Setting up regular (hourly) updates of the Celonis data model using Jenkins.
