    • Computers, a user equipment, a computer system, computer program products, computer programs and a method for a computer system are disclosed. The method comprises the steps of: - receiving user IDs, associated cell IDs and time stamps associated with the cell IDs and the user IDs, - requesting and receiving, from a cell ID database, geographical coordinates corresponding to the cell IDs, - finding stations and times for each user ID based on the geographical coordinates and time stamps associated with each user ID; - exchanging the stations with a place for each one of the stations, - generating at least one OD sub-matrix associated with each user ID based on places and times of arrival and departure associated with these places, and - merging the OD matrices into an OD matrix.

    • The invention is directed towards a query handling device (20) in a federated database system (10) and a method, computer program and computer program product for handling queries in the federated database system. The query handling device (20) receives database queries (Q1, Q2, Q3, Q4) directed towards a group of databases (22, 24, 26, 28) from several applications (Al, A2, A3, A4) and filters the queries based on common query rules such as common query syntax, investigates the queries (Q1, Q2, Q3, Q4) that have passed the filtering, where the investigation comprises prioritising between at least some queries according to a query prioritisation scheme, and sends the investigated queries to the databases, where queries having been prioritised are sent according to the query prioritisation scheme.
    • 本发明针对联合数据库系统(10)中的查询处理设备(20)以及用于处理联合数据库系统中的查询的方法,计算机程序和计算机程序产品。 查询处理装置(20)从几个应用程序(A1,A2,A3,A4)接收针对一组数据库(22,24,26,28)的数据库查询(Q1,Q2,Q3,Q4)并对查询进行过滤 基于通用查询语法等常见查询规则,调查通过过滤的查询(Q1,Q2,Q3,Q4),其中调查包括根据查询优先级排序方案在至少一些查询之间进行优先级排序,并发送调查 根据查询优先排序方案发送查询优先级的数据库。
