The Centralised Securities Database (CSDB) is a single information technology infrastructure, which is operated jointly by the members of the European System of Central Banks (ESCB), including national central banks (NCBs) of non-euro area Member States where such NCBs voluntarily participate in the operation of the CSDB. The CSDB stores item-by-item data, in particular, data on securities, their issuers and prices.〔https://www.ecb.europa.eu/ecb/legal/pdf/l_30720121107en00890103.pdf〕〔https://www.imf.org/external/pubs/ft/bop/2007/07-25b.pdf〕 ==Aims== The aim of the Centralised Securities Database (CSDB) is to hold complete, accurate, consistent and up-to-date information on all individual securities relevant for the statistical purposes of the European System of Central Banks (ESCB). This means securities issued by EU residents; securities likely to be held and transacted in by EU residents; and securities denominated in euro, whoever the issuer is and wherever they are held. The CSDB contains information on over fi ve million debt securities, equities and mutual fund shares/units issued by residents of EU Member States or by others.〔https://www.ecb.europa.eu/pub/pdf/other/centralisedsecuritiesdatabase201002en.pdf〕〔http://www.bde.es/f/webbde/Agenda/Eventos/06/Mar/Fic/19.Pronk.pdf〕〔http://www.statistics.gov.hk/wsc/STS082-P4-S.pdf〕 The development of a single reference securities database in the ESCB – the Centralised Securities Database (CSDB) – is the cornerstone of the transition to security-by-security based securities statistics in Europe. Therefore, the project has the highest strategic priority for the ESCB. The CSDB aims to cover all debt securities (including those with a hybrid structure), shares and mutual fund shares issued or held by euro area residents, as well as all instruments denominated in euro. It currently contains around 4 million individual securities, for which the aim is to store up to around 300 attributes related to the instruments and the issuers; holder information may be added at a later development stage. It is currently sourced by five commercial data providers, 14 EU central banks (NCBs) and internal sources of the European Central Bank (ECB), such as the Financial Markets Database.6 Yet the CSDB may not only be seen as the “catalyst” for the euro area wide transition to security-by-security based collection systems but it is also considered superior to local securities reference database solutions once the initial technical and organisational challenges involved with the setup of a system of such complexity have been successfully tackled: • Higher coverage and data quality: The CSDB consolidates micro data from both ESCB-internal and commercial sources for the common use, thus leading to a higher coverage of instruments and attributes, in particular regarding non-resident issues. Furthermore, data quality management work is shared in a network on the basis of comparative advantages. Efficiency: The common sourcing and quality monitoring provides also for efficiency gains. In addition, the CSDB may obviate the need to update similar databases at national level unless they are needed as a source or for data quality monitoring. • Consistency (cross-border): The CSDB will ensure a consistent classification of the security and issuer features throughout the euro area,8 thereby further increasing the degree of harmonisation of euro area statistics. The CSDB is a pioneer project in many respects. It is unique in terms of its technical setup, in particular the flexible data model in the new (“Phase 2”) system, the large volume of data stored and processed as well as its complex algorithms for the selection of the best out of several “candidate sources”. It is also new in the world of statistics. The CSDB project is the first cooperative project within and even beyond the ESCB statistical function, involving the need to establish, and further develop on an ongoing basis, sound operational business procedures. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Central Securities Database」の詳細全文を読む スポンサード リンク
