Maintenance is Not a Myth
The cost for new development can often be easily justified. If a new function is needed, staffing a team to create such functionality and supporting data structures can be quantified and voted up or down by those controlling resources. Money can be found to build those things that move the organization forward; often, the expense may be covered by savings or increased revenue derived from providing the new services.

No Pain, No Gain
It is not magic. Building a successful IT solution takes time. And that time is used in various ways: obtaining an understanding of the goal; mapping out what components are necessary and how those components interact; testing components and their interaction; and finally migrating those components into the production environment - otherwise known as analysis, design, development, testing, and deployment. Regardless of the methodology employed, these functions must always be addressed. Different approaches focus on differing needs and aspects. But any complete methodology must fill in all the blanks for accomplishing each of these tasks.

Success is an Attitude
When assembling a database design, one of the keys for success is consistency. There should be more than just similarity in the way things are named, the manner in which tables or groups of tables are constructed; the manifestation of these elements should follow standards and practices that are documented and understood. If one tries to rely on the idea that individual developers will simply look at existing tables and glean standards via osmosis as they add on or create new tables, then one does not actually have any standards at all.

Not Everything Ends
Occasionally, one sees a data structure abomination. This atrocity involves an object of almost any type, in almost any database wherein the object has a start date but no end date. It is not that the finish date currently has no value and is null; it is that the end date does not even exist on the table structure. The stop date was never intended to exist. The object in question starts, but it doesn't ever end.

Alpine Data Labs Raises $7.5 Million in Series A Funding and Formally Launches in the U.S.
Alpine Data Labs, developer of Alpine Miner, a solution for big data predictive analytics, has received $7.5 million in Series A funding. In addition, after 15 months of product development, the company also announced its 10th production customer and its formal launch in the U.S. market. According to Anderson Wong, Alpine Labs CEO and co-founder, organizations cannot extract all the possible value from their data because it is growing faster than they can analyze it, they don't have enough resources with analytics expertise, and the tools they're using are too complex to get to the answers they need quickly.

Date-Driven Development
Dates are important. Without dates how can anything be planned? However, due dates have been know to increase in importance in the delivery of software solutions. Sometimes the due date becomes such an overwhelming creature of importance that the date is more important than following best practices, more important than verifying that what is built is correct, more important than the solution team gaining a proper understanding of the work they are attempting to perform.

States and Transitions and the Circle of Life
The understanding of object states and their transitions obviously is of great importance to the solution developers because as processes are built they will need to support each state and every possible transition. Additionally, knowledge of object states and transitions is of vital importance to the data modeler because the data must be persisted across each of those states, and often the state of an object needs to be easily identifiable. A data model minimally requires a reference table, along with the varying entities that reference that table (the foreign keys tracking an individual object's status). Specific states drive variations of required attributes or combinations of those attributes that apply to one state and not another. The logical definition of the database can identify these variations through the use of supertype/subtype constructs.

Referential Integrity Rules Must Stand Alone
Referential integrity helps manage data by enforcing validation between related entities. This enforcement follows logical semantics behind the database design -- i.e., an employee can only work for an already defined department; a prescription can only be written by a health care practitioner with the proper authority. A Foreign Key on an Employee table rejects data when any attempt is made to insert or update a row with a department value that does not already exist as a department identifier within a Department table.

Preserving Data Integrity
When designing a system an architect must conform to all three corners of the CIA (Confidentiality, Integrity and Accessibility) triangle. System requirements for data confidentiality are driven not only by business rules but also by legal and compliance requirements. As such, the data confidentiality (when required) must be preserved at any cost and irrespective of performance, availability or any other implications. Integrity and Accessibility, the other two sides of triangle, may have some flexibility in design.

How Many Data Models Does It Take?
Back in the 1970s, the ANSI SPARC three-tiered model arose, foreshadowing a smooth intertwining of data and architectural design. The three tiers concept isolated the physical storage needs of data structures independent of business' perception of these structures. The three levels were comprised of schemas labeled external, conceptual, and internal, with each level describing the data in focus from varying perspectives.

Filling the Knowledge Gaps
How does one know what one doesn't know? When evaluating what one knows, it is hard to know where to begin. The wise men say, "The more you know, the more you know you don't know." If one believes such commentary, what is known constitutes the tip of the proverbial iceberg. Databases have an easier time with such missing circumstances. If the rows of a database table are lacking referents, an outer join query filtering for NULLs might detail for you all the missing items. In developing and delivering projects, such a reference list for our minds to link to does not exist, for an outer join or anything else. Often, we do not know everything that needs to be done, particularly as a project starts. The difference between success and failure is not so much what one knows, but in how one handles the gaps between what is known now and what needs to be known before one finishes.
