OZROX acts as the hub for a number of sample-centred laboratory databases, such as petrography, whole-rock geochemistry and isotopic age determin-ations. Other databases, like mineral deposits, regolith-terrain mapping and stream-sediment geochemistry, link to the sites component of the field database. In addition, links have been set up to the National Petroleum Database, the STRATDAT bio-stratigraphic database, and the new Rock Store Database. </p><p>Wherever possible, the data entered are controlled by the means of lookup tables or databases, to facilitate the presentation of data with geographic infonnation systems and other computer applications. For example, fonnation names are tied to the Australian Stratigraphic Names Database, geological time terms are validated by a GEOTIME table, and mineral names are validated by an AGSO list of mineral names and abbreviations. Without such rigorous validation of input data it is difficult to use the database for automated analysis and presentation of data. </p><p>This guide presents an overview of the database, and describes in detail the menus and screen fonns used to input and view the data. In particular, the definitions of most fields in the database are given in some depth under descriptions of the screen forms -providing, in effect, a data dictionary of the database. The database schema, with all definitions of tables, views and indexes is contained in Appendix A. </p><p> Australian Geological Survey Organisation 1995 - Guide to OZROX ii </p></li><li><p>1 . INTRODUCTION </p><p>The OZROX Field Geology Database accommodates five main categories of field geological data - site locations, outcrops, measured sections and drill holes, lithologies and samples, and structural geology readings. It records much of what AGSO geologists normally write in their field notebook, but in an organised way that lends itself to automated methods of data manipulation and presentation. Structured notebooks for use with the database have been printed (Blewett 1993). The database has also been designed to mesh with geographic information systems (GIS) such as AGSO's ArclInfo system (Chopra &amp; Ryburn 1993, 1994a, b). </p><p>This guide describes the infrastructure of the OZROX Field Geology Database. It supersedes an earlier guide to the 'NGMA Field Database' (Ryburn et al. 1993). Details of the structure and workings of the database, its main screen forms and the purpose of all fields are given. The full OZROX schema is listed in Appendix A. </p><p>2 HARDWARE AND SOFTWARE ENVIRONMENT </p><p>Together with the majority of AGSO's attribute geoscience databases, OZROX is implemented on AGSO's corporate database management system, which is Oracle 7 running on a DG AViiON 6250 server under the UNIX 5.4 operating system. It is accessible throughout AGSO via a TCPIIP Ethernet backbone, which is bridged to seven local Novell PC LANs. At the PC level Novell's 'LAN Workplace for DOS' provides VT220 terminal emulation. Database entry and query forms are generated centrally from the A ViiON server via Oracle Forms 3. This system is now changing to graphical client/server applications in Oracle Forms 4.5, or later, running on PCs with Microsoft Windows, Apple Macintoshes and UNIX X-Windows workstations. </p><p>AGSO's Oracle system has been set up with two instances - 'Test' and 'Production'. The Test environment is used mainly for development purposes, and has only a small subset of the OZROX dataset. OZROX users are' only concerned with the Production version of the database. Full explanations of the hardware and software environment were presented for users by Lenz et al. (1993), and for developers by Kucka (1994). </p><p>3 AGSO's GEOLOGICAL DATABASE SYSTEM </p><p>AGSO's Geological Database System (Fig. 1) consists of a number of field and laboratory databases that surround the OZROX Field Geology Database and share resources such as the Australian Stratigraphic Names Database (Ryburn et al. 1995) and the AGSOREFS Bibliographic Reference Database (Ryburn &amp; Bond 1995). Originally set up by what is now the Division of Regional Geology and Minerals </p><p> Australian Geological Survey Organisation 1995 - Guide to OZROX </p></li><li><p>(RGM) in collaboration with Information Services Division (ISD) (Ryburn et al. 1993), the system is increasingly used by other divisions in AGSO. The system was designed and constructed by the National Geoscience Database Development Project, which is a part of lSD's National Geoscience Information System (NGIS) Program. </p><p>OZROX acts as the nucleus of the Geological Database System. Some databases, like OZMIN mineral deposits (Ewers &amp; Ryburn 1993), RTMAP regolith landform mapping (Hazell et al. 1995) and STREAMCHEM stream sediment geochemistry link directly to point location data in the SITES table in OZROX. Other databases, like PETROG petrography (Ryburn et al. 1994c), OZCHRON geochronology (Ryburn et al. 1993b) ROCKCHEM whole-rock geochemistry (Ryburn 1990, Hazell et al. 1995) and Rock Store are linked to OZROX via data in the ROCKS table. </p><p>Figure 1. Simplified diagram of AGSO's Geological Database System </p><p>The rationale for establishing a corporate geological database system is to ensure that all field and laboratory data are stored in a manner that is secure, ordered, accessible and cost-effective, and in a form that will be compatible with future methods of data analysis, distribution and presentation. Ways of distributing such data are currently undergoing a revolution, with the rapid acceptance of the Internet and the World Wide Web as the de-facto standards for on-line public access. By using a mainstream corporate relational database management system (RDBMS) like Oracle we can be confident that secure public access will be easily provided in future systems. We anticipate that most data in OZROX will soon be publicly accessible on AGSO's World Wide Web server, and in spatial formats. We expect that the user will be able to generate in real time, and at different scales, maps with site and sample information. These, in tum, will point to laboratory data that can be purchased -eventually via the Web, using automated charging methods. </p><p> Australian Geological Survey Organisation 1995 - Guide to OZROX 2 </p></li><li><p>4 - STRUCTURE OF OZROX </p><p>The OZROX Field Geology Database now has seven main data tables - SITES, OUTCROPS, SECTHOLES, INTERIZONS, ROCKS, LITHDATA and STRUCTURES. All other tables indicated in Figure 2 below are lookup or authority tables used to validate the classifications and nomenclature used in the main tables :-</p><p>Figure 2. The structure of OZROX showing relationships between tables, with 'crows' feet' at the many end of many-to-one linkages. The rounded boxes represent databases used to validate the data in OZROX. </p><p>The hub of the field database is the SITES table, which standardises the way point location data are recorded and ensures that the accuracy and lineage of coordinates are noted. This is logically linked to the OUTCROPS and ROCKS tables via the Originator Number and Site ID (see Section 5). The OUTCROPS table stores data at the outcrop level, including links to the STRATDAT biostratigraphic database. The SECTHOLES table has data on measured sections and drill holes and INTERIZONS (intervals and horizons) their columnar geological logs. The ROCKS and LITHDATA tables record lithologies and samples taken. LITHDATA is the </p><p> Australian Geological Survey Organisation 1995 - Guide to OZROX 3 </p></li><li><p>expandable attributes table for ROCKS - linked, via an automatically generated keyknown as Rockno. Validation of stratigraphic units and geological provinces isaccomplished by links to the Australian Stratigraphic Names Database and theGEOPROVS table. Descriptions of the screen forms associated with these objects areincluded in this manual. The main data tables in OZROX are owned by the Oracleuser 'NGMA'. The ownership of all tables is indicated in full table names by a prefixoccurring before the period. The main NGMA data tables are as follows :-</p><p>TABLE NAMENGMA.SITESNGMA.OUTCROPSNGMA.SECTHOLESNGMAINTERIZONSNGMA.ROCKSNGMALITHDATANGMA.STRUCTURES</p><p>CONTENTS ground sites location, accuracy &amp; lineageoutcrop-related data, plus biostratigraphymeasured section and drill hole datacolumnar geological logs for SECTHOLESrock samples and lithological dataextendable attributes for the ROCKS tablemesoscopic structures at a site or outcrop</p><p>There are also views of these tables for authorised users to add, update and delete theirdata. These views, called US11t,S, UOUTCROPS, USECTHOLES, UNTERIZONS,UROCKS, ULITHDATA and USTRUCTURES, are described more fully in section 4on security and access. In addition to the above main data tables there are a number ofauthority tables and one view, not all of which belong to NGMA</p><p>TABLE NAME NGMA.OZROX_USERSNGMA.ORIGINATORSNGMA.AGSOCOUNTRIESNGMA.AGSOSTATESNGMA.GEOREGIONSNGMA.QMAPSNGMA.HMAPSNGMA.LOCMETHODSQUATDB.VEGETRTMAP.LANDFNGMA.SECTYPESNGMAJZ_RECTYPESNGMA.CONTACTSNGMA.ROCKTYPESNGMALITHOLOGIESNGMA.LITHDATATYPESNGMA.AGSOM1NERALSNGMA.LITHUNITSNGMA.STRUCTYPESSTRATA.GEOPROVSGEODX.STRATNAMESSTRATA.GEOTIME</p><p>CONTENTS record-level security tablecontributors of datalist of countrieslist of Australian Stateslist of geological region polygonsAustralian 1:250000 map sheetsAustralian 1:100 000 map sheetsspatial location methodsAustralian vegetation classificationAustralian landform classificationmeasured section/drill hole typesinterval &amp; horizon record typeslist of lithology contacts typesbasic classification of rock typesEthological names &amp; qualifiersextendable lithological attributesAGSO mineral nameslithological units &amp; map symbolsextendable structure attributesAustralian geological provincesAustralian stratigraphic namesgeological time scale</p><p>CUSTODIANMurray HazellMurray HazellRod RyburnRod RyburnMurray HazellMurray HazellMurray Hazel!Richard BlewettGeoff HuntColin PainMurray HazellRod RyburnMurray HazellLesley WybomJan KnutsonMurray Hazel!Morrie DugganMurray HazellRichard BlewettDavid PalfreymanCathy BrownJohn Laurie</p><p> Australian Geological Survey Organisation 1995 -^Guide to OZROX^</p><p>4</p></li><li><p>As a general rule, only the designated custodians are permitted to change the data in these tables. Full definitions of all tables, indexes and views used by the NGMA Field</p><p>Database are given in Appendix A.0</p><p>5- SECURITY AND ACCESS</p><p>Select-Only Database Access</p><p>The Oracle production environment allows all Oracle users, including external users, select-only access to nearly all tables in the OZROX Field Database. The menu</p><p>system provides 'read-only' versions of the forms that allow users to retrieve most ofthe data, but not to insert, update or delete data. In the SQL*Plus command-line</p><p> environment, all users may select data from any of these tables provided they includethe owner's name plus a full stop in the full name of the table or view, e.g. :-</p><p>SELECT SITEID FROM NGMA.OUTCROPS WHERE ORIGNO = 56;</p><p>Not all of the tables in OZROX are owned by NGMA. Tables from the AustralianStratigraphic Authority Database are owned by STRATA or GEODX, while RTMAPowns the Landforms Table, and QUATDB owns the Vegetation Table.</p><p>Insert, Update and Delete Access</p><p>OZROX users wishing to enter new data or update existing data must use the'insert/update' versions of the data forms. With these forms they only get to see theirown data, or data belonging to other users for which they have specifically been giveninsert/update/delete privileges. The same security arrangement applies to the insert/update views of all the main data tables in OZROX.</p><p>Insert, update and delete privileges on OZROX's data tables are now controlled at therecord level by the following Database Security Form (Fig. 3), which corresponds tothe OZROX_USERS table (see Appendix A). Only a few people are able to add, alteror remove records in this table. The form is accessible from screen 2 of the MainGeological Databases Menu (Item 9 in Fig. 4). The security data in this table arevisible to internal AGSO users, who are the only people allowed to insert, update ordelete records in OZROX data tables.</p><p>For a user to enter data into OZROX there must be a record in OZROX_USERS inwhich the user's Oracle ID occurs in both User 1 and User 2, with an 'X' in theOZROX (`DB1') column. In Figure 3, JSMITH can enter data into OZROX, as wellas into ROCKCHEM, RTMAP and OZM1N. In the second record shown in Figure 3,JSMITH has also been given update privileges on all records belonging to</p><p> Australian Geological Survey Organisation 1995 -^Guide to OZROX^5</p></li><li><p>`BBROWN' in all four databases. In the third record, JSMITH's update privilegesover JJONES' records extend only to the OXROX database. The `R' used in place ofan 'X' in Figure 3 indicates the users in question can access all restricted records inROCKCHEM or OZMIN. Most users only get to see restricted records that theythemselves have entered. The OZROX database does not have any restricted records.</p><p>VT220 Terminal to AVii ONSECURITY TABLEDATABASE</p><p>User 1 has update&amp; dele...</p></li></ul>
