In data warehouses indexing is becoming a common feature to accelerate data mining searches that combine multiple restrictive queries. Different types of indexes had been proposed and some of them are already implemented. This paper proposes a new kind of join index structure, which can be useful for multiple join operations. The algorithm to build this type of index structure is presented. Some queries, which benefit from this kind of join index, are also presented.

Classification and indexation process is a hard one for librarians all over the world. A software system can ease their work and make the process more accurate. We present in our paper methods for classifying and indexing publications, suitable for such a system and analyze different storage and index database management systems capabilities in order to use them as support for classification, indexation and retrieval processes in an integrated software system for libraries. Furthermore, the problem of storing and retrieval of full content of a publication is taken into consideration.

Today, software applications used in different domains contains and manage databases. The performance of these applications is determined in a great deal by the database structure and its capability to respond in a short and consistent way to the users needs. So, database design is an important step in the information system life cycle and it should be done in a proper manner. The paper presents an optimization algorithm for physical database design based on "Cleanroom" model. The algorithm helps to obtain an optimal structure for the database and to eliminate errors from the database designing process.

They need to collect, manage and transform more and more data with a complex structure. These data are nowadays organized in data warehouses. To accelerate data mining searches that combine multiple restrictive queries indexing techniques are usually used. The paper proposes a new multiple join index structure, which is useful for multiple join operations between tables. The algorithm to build this index structure is presented and, also, some types of queries that can be accelerated with the index help.
