WebEx BroadcastOctober 4, 2013
What is a database?
a comprehensive collection of related data organized for convenient access, generally in a computer
a comprehensive collection of related data organized for convenient access, generally in a computer
Phone book Dictionary Index books
Per definition, database is simply the data
A Program or System is what facilitates entry and processing of that data
The terms ‘Database’ and ‘Database System’ are essentially interchangeable
Database vs. Database Program or System
Courthouse Indexes Printed and electronic
State Mineral Websites (Sonris, NDIC, etc.)
Search Engines Google Bing
Social Media Facebook Linked In
Everyday databases in land work
And of course…
Spreadsheets Simple but powerful
Sorting Arithmetic
We will revisit spreadsheets when we discuss design options
Everyday databases in land work
Image files may contain “metadata”
State Mineral Websites Well and production data Vs. Associated image of document
Images and Associated Files vs. Data
Benefits of an Electronic Database
Speed Accuracy Convenience Control Standardization
Normalization
Benefits of Electronic Databases
Speed Generally real-time Data is already normalized (see below) Info not only gathered but manipulated
instantly Accuracy
Not subject to human mistakes
Benefits of an Electronic Database
Convenience Don’t have to handle paper sources Web access even better Database program gathers and
manipulates data for you
Benefits of an Electronic Database Control
Very easy based on User IDs, authority levels
Types of authority Degrees or areas of access
Prospects States Divisions
Standardization Users select from options Normalization
Table structure and general design tailored to task
Drawbacks of an Electronic Database
Security, Security, Security
Users Hackers Viruses Failures Disasters
Two Types of Databases Flat
Spreadsheets Easier to set up, more difficult to
maintain Has orientation as described below Much data repetition
Relational Related tables More difficult to set up, easier to
maintain
Two Three Types of Databases
Worth mentioning…
Object Oriented Tables not directly related Usually best for very large
amounts of data with relatively few tables
Database Permission Types
Four broad types of permission Read Write Edit Delete
Much of what we have discussed is read access only
Divided into 2 broad categories Acquisition/Tracking
Tract-oriented database Concerned with % signed, restrictions,
etc.
Management Contract-oriented database Concerned with rights and obligations
Databases for the Land Industry
Several companies TotaLand iLandman Land Boss
Commonly tract-oriented Document generation (leases, reports,
etc.) Real-time reporting Linking to GIS Data Gathering
Field Acquisition and Tracking Systems
Tract-Oriented Design
Note the repetition of records
Leading companies Tobin Quorum Land Pro
Generally contract-oriented Tracking of rights, obligations over
time Deaths, sales, expirations WI, RI, ORRI, NPRI
Division Orders Joint Interest Billing
Asset Management Systems
Contract-Oriented Design
Again, note the
repetition of records
Non-Oriented DesignCross Tables as opposed to Sub Tables
Each design has pros and cons All systems attempt to relate key data
Tracts Contracts Parties Units Wells Instruments Projects Payments Etc., etc.
Common Thread
Flat – Tract OrientedRelational – Tract
Oriented
Flat – Contract Oriented Relational – Contract Oriented
N/A Relational – Non Oriented
Review - Electronic Databases
Review - Electronic Databases
Tract-oriented Contract-oriented Non-oriented
Databases are all around us Electronic databases are critical to
everyday life, and the land industry is no exception
Generally speaking, the front end side of the land industry has been slow to embrace significant integration of databases
Solutions are getting better, prices are coming down
Get on the bus or get left behind…
