    Card files in use for over 20 years (still referred to infrequently)

    Data sheets still used in some collections Hardcopy Era: Earliest Museum register in 1877. Traditional registers used till 2000 (or later) in some collectionsDatabasing at the AM falls into two eras hard copy and digital.

    The Australian Museum is Australias oldest museum.Commenced housing collections in 1827.Characterised by still having large and active research and collect branches in a wide variety of fields of natural history and anthropology.Material continues to flow into the collection at a prodigious rate. Collections had been accumulating at the Museum for over 100 years before digital databasing was even a possible option.The technology and hardware employed has steadily grown in sophistication.However, digital collection management within sections of the museum evolved independently, and largely on an ad hoc basis.The most widely utilised platform for databasing in the Museum prior to the transfer to EMu was KE Titan, followed by KE Texpress.However, Texpress databases were customised individually for each user discipline, and each collections database was entirely separate from any other discipline.When databasing started, it was initially intended to be for vertebrate groups only. It was only later that it was decided to incorporate other disciplines.The different collection databases vary significantly in terms of degree of sophistication.Some are essentially just flat files, others have varying degrees of relational complexity.Many are utilised to perform daily collection management tasks, such as producing loans transaction forms and specimen identification labels.They are often utilised by scientific researchers, who require bulk data dumps.They provide a data source for many web services, such as OZCAM, FaunaNet etc.KE provide the option for individual customisation to institutions needs.A balance needs to be struck between user desires and the resulting impacts in terms of time delays in the migration process, financial cost, and unnecessary complication of the database design.Particularly difficult when transferring users from a flat file design.

    An example of a complicated but necessary modification during the data migration process.Necessary because locational data is critically important in natural history collections.Data is collected in different formats by different departments.Accuracy/precision is lost when transferring from one co-ordinate system to another.Need both a common co-ordinate system for mapping in GIS, and to preserve the original co-ordinates in their original format.

    Other examples of essential customisations are the Preparations tabs, which allow the recording of several objects (with different data field requirements) under the same registration number, and the Mixed Taxa tab which allows several objects with differing taxonomy to be recorded under the same registration number.

    These are examples of design modifications that in hindsight were probably less important, possibly even unnecessary.This is because they have a lot of repetition of essentially the same fields.In addition, most of the data in these fields could have effectively been housed on the Measurements tab.Often, these sort of design changes are requested by users coming from a flat file system, where data is typically stored in this manner.It also arises because of user desires to have all their own data entry fields in the one place rather than having to switch between tabs or modules.A major challenge of requesting client customisation therefore lies in balancing between essential user-specific design changes and those which either offer limited benefit or can even be seen as detrimental in terms of over-complicating the overall design. Then selling it back to the users.

    The registry allows a high degree of custmisation of permissions for both users and user groups.However, this is still limited to a certain degree by the fact that privileges tend to be all or nothing.For example, you can either insert a record or you cant. You can either be able to bulk edit records, edit one record at a time, or not be able to edit records at all.Historically, the Museum databases grew in isolation of each other.Databsing was purely part of collection management practices, and the data for each discipline was the responsibility of each collection division.Each division therefore had a number of users, commonly all utilising database tools that under the EMu system should require quite senior administrative privileges.We are therefore moving from a set of isolated systems with little record security to a shared database system employing tiered record security (higher level permissions granted to successively fewer people).Allow one-to-many relationships between two modules in both directions.

    Allow one field in one module to be linked to multiple fields in another module, or multiple other modules.

    Editing without due consideration of potential implications for other attached records can have disastrous implications!!!!!!

    .Especially once data sets are shared between disciplines.One of the more obvious solutions for ensuring record security and protection from accidental corruption by another user.but is it perfect for our needs?For one thing, we do not necessarily want to prevent other users from utilising records field collections are often multi-disciplinary, so there are many instances where different departments may have unique Collection Event data, but share Site data. The Bibliography module also presents a good example of where records could quite likely be shared between disciplines.There is a considerable amount of legacy data already in the system, and some has already been linked inter-departmentally. Record security setting can stop people from being able to access this record completely (not even viewable), which means if it is already attached to one of their own records they are locked out from even fixing it.On a more general level, it requires registry permissions to be set for a user in order for them to utilise this facility, as well as edit permissions for that particular record. If daSecurity is not set for all users, who sets the record security for new records? If it is set for all users there is an increased risk of records being locked when they perhaps shouldnt be.One thing we have tried to do is to add fields to modules allowing records to be tagged with a Discipline jurisdiction, or ownershipThis allows any user thinking of utilising this record as an attachment to one of their own records which department was responsible for the original data entry. If it was from another department, they should avoid editing the record if it doesnt quite suit their purpose.Data security can be aided by adding query and insert defau
