Opis:
Extensible Markup Language was mainly designed to easily represent documents; however, it has evolved and is now widely used for the representation of arbitrary data structures. There are many Application Programming Interfaces (APIs) to aid software developers with processing XML data. There are also many languages for querying and transforming XML, such as XPath or XQuery, which are widely used in this field. However, because of the great flexibility of XML documents, there are no unified data storing and processing standards, tools, or systems. On the other hand, a relational model is still the most-commonly and widely used standard for storing and querying data. Many Database Management Systems consist of components for loading and transforming hierarchical data. DB2 pureXML or Oracle SQLX are some of the most-recognized examples. Unfortunately, all of them require knowledge of additional tools, standards, and languages dedicated to accessing hierarchical data (for example, XPath or XQuery). Transforming XML documents into a (quasi)relational model and then querying (transformed) documents with SQL or SQL–like queries would significantly simplify the development of data-oriented systems and applications. In this paper, an implementation of the SQLxD query system is proposed. The XML documents are converted into a quasi-relational model (preserving their hierarchical structure), and the SQL–like language based on SQL-92 allows for efficient data querying.

Opis:
It is a common knowledge, that quality of a manufactured product highly depends on quality of its components. This especially might be a problem, if a component comes from external supplier, whose processes are normally beyond our control. The paper addresses a procedure called PPAP (Production Part Approval Process abbreviation known from Ford, Chrysler, General Motors manuals, issued by AIAG) which has been widely used in automotive industry to assure good quality deliveries from suppliers, beginning from early stage of cooperation, before start of production. PPAP requirements are shown as a way customer and supplier agrees upon not only product quality, but also upon manufacturing process, which must meet specified standards, set by customer (e.g. documentation, records, capability, stability, confidence in measurements etc.). The paper includes authors' assessment of resources necessary for a supplier to provide in order to meet customer's PPAP requirements. Also, reasons and perspectives of PPAP development are discussed, basing on documents proving PPAP - like practices noticeable in industries having little or nothing in common with automotive industry. In conclusion, PPAP is presented as a procedure imposed on suppliers by customers, who, being well aware of weaknesses of certified Quality Management Systems with respect to management of preventive actions in supplier's manufacturing processes, needs a strong proof that a supplier effectively introduced relevant preventive actions to a manufacturing process before it starts production of goods for a customer.

Opis:
One of the requirements of the process approach is to identify the methods and evaluation criteria for process measurement. The effectiveness described as the ability to execute scheduled tasks and the objectives may be the measure used to evaluate processes. The article presents a few concepts of efficiency indicators that can be used in assessing the activities carried out within the framework of the implementation of new projects, according to APQP&PPAP guidelines. This paper proposes four concepts of indicators to assess the effectiveness of the above-described process, including index based on the Taguchi loss function.

Opis:
One of the requirements of the process approach is to identify the methods and evaluation criteria for process measurement. Efficiency described as the ability to achieve planned results with respect to consumed resources may be a measure used for evaluation of processes. The article presents a few concepts of efficiency indicators that can be used in assessing the activities carried out within the framework of the implementation of new projects, according to standards of automotive industry. These standards are: APQP (Advanced Product Quality Planning) and its integral part, used in the final stage of validation of the product and process, known as PPAP (Production Part Approval Process). The paper proposes three concepts of indicators assessing the efficiency of the above-described process and one concept of calculating the efficiency indicator based on the Taguchis loss function.
