These include a full suite of social network analysis tools, advanced image processing algorithms, and a context-sensitive input assistant. Mathematica employs a hybrid numerical-symbolic computing approach to analyzing problems and finding solutions. It makes use of automation to increase productivity in key areas of computing, visualization, and development. In essence, it's an all-in-one platform that supports programming languages that follow different paradigms, provides community support with a built-in knowledge base, and implements a document-based workflow.Section 2. Creating Databases and Spreadsheets # 2.1 General Considerations #Īs stated previously, it is not the place of this guide to provide guidance on creation of either spreadsheets or databases beyond considerations that have a significant impact upon the preservation of a certain type of dataset. The following are general pointers on ensuring that data is both consistent and easily reusable and remains so throughout its preservation lifecycle.

Use controlled vocabularies and established word lists where possible for data entry in both spreadsheets and databases.Adhere to consistent and meaningful table/sheet and field/column naming conventions and be aware that tables or sheets may not always remain packaged together within a single file.While some applications allow these, such elements are best avoided as they can present a problem in future data migrations.Īlso be aware that some applications restrict the use of the certain field names (e.g.ORACLE cannot have tables that start with a number or fields named 'desc' or 'date') or even the use of spaces within field or column names.In spreadsheets, don't use styles and formatting to convey meaning as this can be lost when the data is migrated or used within different applications.The table below outlines some of the common formats used to create spreadsheets and databases and describes their associated applications and potential uses for long term preservation. Proprietary Microsoft format used by Access databases (2007 onwards) As with many word processing applications, spreadsheets in particular have seen a move in recent years towards support for common XML-based file formats and it is worth noting that many applications such as Microsoft Office, OpenOffice and WordPerfect Office have support for both Office Open XML (OOXML) and OpenDocument Format (ODF) file formats. Accdb format was first introduced in Access 2007 and continued with Access 2010 and was developed in order to include enhanced functionality over the previous.
