3 TURKISH STATISTICAL INSTITUTE TurkStat Databases Production Database : Current data is stored and always transaction in it. Institutional Database (Enterprise Database): The main repository of TurkStats harmonized historical data. Dissemination Database : Aggregated time series data created from TurkStat institutional databases. Up to now there are 62 institutional databases 59 dissemination databases
Oracle DBMS is used for all database INFORMATION TECHNOLOGIES DEPARTMENT 4 TURKISH STATISTICAL INSTITUTE Production Databases Mainly data entry systems
Database for web applications OLTP(Online Transactional Processing) Surveys data are stored in this database Huge amount of data entry and frequent data manipulation(inserts, updates, deletes)
Various but not costly SQLs Supports thousands of concurrent users We developed a new generic system (Harzemli) that produces surveys generic using DDL. Regional Offices use this program on the netbooks. INFORMATION TECHNOLOGIES DEPARTMENT
5 TURKISH STATISTICAL INSTITUTE Institutional (Enterprise) Databases Institutional database has analysed, harmonized and controlled consistency eventual time series data. Only for internal users. User roles are defined for the statistical units on the newly created institutional databases. The statistical units can access only their own data using SAS codes , and just have select right. They can never delete, update, insert data by themselves. It is necessity for all departments to work in coordination with IT Department during the creation process of institutional databases.
INFORMATION TECHNOLOGIES DEPARTMENT 6 TURKISH STATISTICAL INSTITUTE Dissemination Databases Dissemination databases are the summary aggregated data repository which are created from institutional databases according to the information request The dissemination database is served on the TurkStat web page They are READ-ONLY system For external users, only confidental data is available It is free of charge, shown on web page
Since it is open to whole world, supports many concurrent users INFORMATION TECHNOLOGIES DEPARTMENT 7 TURKISH STATISTICAL INSTITUTE There are aggregated time-series data about 62 subjects. End users can easily get desired data with the help of interface programs and dynamic reports The current web-based programmes are developed by our programmers with ZK framework and Oracle reports We are developing a new Central Dissemination Project that will show all dissemination data by one software programme
INFORMATION TECHNOLOGIES DEPARTMENT 8 TURKISH STATISTICAL INSTITUTE The main benefits of distinction to these 3 database is: To maintain different business processes on different servers. An advantage is performance. While we are making a bulk insertings or queries on instutional database, dissemination database doesnt effect these procedures. So the performance would not be decreased. Another advantage is only aggregated data are served to internet users
and access to micro data is prevented INFORMATION TECHNOLOGIES DEPARTMENT 9 TURKISH STATISTICAL INSTITUTE Data Harmonization The main subject of the Institutional databases is harmonization of different data After carefull investigations and analyses, it has been seen that our main problems comes from using different classifications from year to year and projects to projects Such as
Branch of economic activity Occupational group Educational status Marital Status Administrative Structure Dictionary tables INFORMATION TECHNOLOGIES DEPARTMENT 10 TURKISH STATISTICAL INSTITUTE Data Warehouse in Turkstat Being holded in our relational institutional database
Designed as star schema model ROLAP (Relational OLAP) which means that all OLAP cubes are on relational database INFORMATION TECHNOLOGIES DEPARTMENT 11 TURKISH STATISTICAL INSTITUTE Data Warehouse in Turkstat (Contd) Being holded in our institution at the scope of European Union projects, Creating data warehouse process was started in 2006 , with SAS And a prototype data warehouse consists of 1985, 1990 and 2000 population censuses were formed
Oracle BI suite is used. INFORMATION TECHNOLOGIES DEPARTMENT 12 TURKISH STATISTICAL INSTITUTE Data Warehouse in Turkstat (Contd) 8 data warehouses / OLAP projects with 48 data marts: 2000 Population Census 1990 Population Census 1985 Population Census Labour Force Statistics Municipal Waste Statistics
Municipal Water Statistics Foreign Trade Statisics Demographical Statistical Datawarehouses in Institutional database. There are different schemas for each Datawarehouse. SQL Procesures are used as ETL, to producing DW data. INFORMATION TECHNOLOGIES DEPARTMENT 13 TURKISH STATISTICAL INSTITUTE Oracle BI Suite

INFORMATION TECHNOLOGIES DEPARTMENT 19 TURKISH STATISTICAL INSTITUTE OBIEE Interface (table and chart) INFORMATION TECHNOLOGIES DEPARTMENT 20 TURKISH STATISTICAL INSTITUTE OBIEE Interactive Dashboards
Simply containers for reports and other content (like chart, maps..) Allows multiple reports to be displayed in a tabbed interface Used to provide highly summarized and graphical content INFORMATION TECHNOLOGIES DEPARTMENT 21 TURKISH STATISTICAL INSTITUTE An Example Interactive Dashboard INFORMATION TECHNOLOGIES DEPARTMENT
22 TURKISH STATISTICAL INSTITUTE Summary Databases of the TurkStat are Production, Institutional and Dissemination Seperating databases to 3 database is useful both performance, management, confidentality We have some Data Warehose Projects developed by Oracle BI Suite Oracle BI suite has Administarion Console, Presentetion Interface, Reports Building tool Dashboards are containers that can include various and dynamic reports, maps, charts etc., and give very easy and valuable data to the users INFORMATION TECHNOLOGIES DEPARTMENT
