Dirty data is incorrect or incomplete input and can originate in many ways. However, we should also consider the method through which data is determined to be, in fact, dirty. For example, a record may have the incorrect address for a customer but that isn't to say that when the record was created the address was incorrect, it may have changed. Timing and maintenance also play a role.

Generally speaking, data is moved through a three step process known as E.T.L. (Extract, Transform & Load). Extraction is the process of sourcing the data; data entry or from a device or location. Transformation is the process used to validate and coerce the data into predetermined formats. Loading is the process by which the formated data is moved to it's destination.

Most dirty data originates from processes involving data entry and is a result of human err, poorly defined or understood process requirements and/or inadequate validation/error handling methods.

The first step is to completely and accurately define requirements. What data is being collected, where does it come from and how often (Extraction)? How will the data be validated and errors reported (Transformation)? How will it be stored (Loading)?

Only after these questions have been answered can the E.T.L. process can be designed. Once designed, the process requirements are disseminated to the extraction source.

Within user based extraction processes there are many common methods to reduce dirty data. Some of these are; spell checks, data type validations, required fields and value limited input controls such as check, combo and list boxes. When designing the extraction method (or front end for user based systems) the general rule of thumb is the less data entry the better. Other common methods include tool tips (floating help boxes), top to bottom, left to right, tab ordered fields (for heads down data entry) and visual/audible cues for data validation exceptions.

No, you do not have to have an Apple TV to connect your iPad to the TV. The Apple TV adds convenience because you can display video from your iPad wirelessly on your TV by using the Apple TV. You can connect your iPad directly to your TV but you will need to buy an AV cable.

1) In a traditional file processing system the work of IT was very hectic while this is not so in DBMS.2) In DBMS redundancy of data is tried to reduced while this was not so in FPS.

3) DBMS maintains data integrity but FPS do not.

Not really. A simple list of data typed up, which you can do in a desktop publishing application, is a database in its simplest form. You can create a table and type data into it, but you cannot really manipulate it and do things with it that you can do with a table in a proper database application. Desktop Publishing does not provide the facilities to create databases and manipulate them, so if you want to create a proper database you would not use a desktop publishing application.

A "database" is a collection of information, often organized in tables. OSPF routers - i.e., routers that implement the OSPF routing protocols - need to maintain several databases, for example, a neighbor database (a list of connected neighbors), and a link-state database (a list of all the connections between different routers in the same area, which the router has learned about).

Table design in Microsoft Access can be performed by right clicking the table name in navigation view (column that runs down the left hand side of Access that is headed 'All Access Objects' by default) or by clicking the "geometry set" icon on the far left hand side of the ribbon called "View" with the table actually open. In Design view you can create and rename fields and assign a "Data Type" to represent the type of data being entered into each field such as Text, Date, Number etc. Hope this helps.

Field/column names in a data table are often cryptic. Because a form can have labels and can contain descriptions for each input field of the table, the data input clerk can more easily input the data without having to know what the cryptic names mean. Forms also allow flow control for the data. If one field contains a specific entry, the form can disable other input fields if they are not necessary. For example, if the country field of a record indicates that the location is outside of the United States, then the state field can be disabled or even modified to provide a selection list of states/provinces in that country.

database systems work with relational databases(well structured data) while information retrieval system works on unstructured data (raw text files/documents).

in database systems main datastructure used is relational tables with well define values for each row and column ont the other hand IR system uses Inverted index which is the index of {term,docIDs} entries. for each term there is a corresponding postings list(the list of documents in which the term is present)/

database sytems work on data that are related to each other and have a well defined domain while IR systems may or may not have such a luxury.

I have clear understanding of project cycle management and I have guided project planning, implementation, monitoring, review and evaluation using the project cycle management principles. I review annual workplan or detailed implementation plan with program managers and provide technical support in the course of project implementation. Using Output to purpose (OTP) tool, in collaboration with CRS/Nigeria local partners in the Niger Delta, we reviewed CRS/Nigeria funded Extricates project and realigned the project output, intermediate results and objectives.

One of the tenets of relational database design is "normalization". Normalization is the process of reducing a complex data structure into its simplest, most stable structure. In general, the process entails the removal of redundant attributes, keys, and relationships from a conceptual data model. In database design one has to make decisions about the trade offs offered by normalization. A completely normalized database can offer a great deal less redundancy and offer a infinite complexity and relational flexibility to the user/designer. On the other hand, this can get out of hand. The downside is that queries get overly complex and it can slow the database to a crawl as more and more data is accumulated. A simple example would be that of a database that represents an address book. The simplest design would be a flat database or a single table with columns like name, address, home phone, work phone. This would be a very fast, easily queried database but somewhat limited. What if you have someone who has more than two phone numbers? what if you want to put in their work address or the address of their vacation home. The fully normalized version of this database would have a core table for contacts that would link to a table of addresses, a table of phone numbers, a table of zip codes. There would also be tables called look up or type or category tables that would list the possible categories for phone numbers such as work, home, fax, cell etc.. as well as a table for address categories, work, home, vacation house etc.. you could also add a category table for the relationships between you and the contact and one for the relationships between contacts e.g, 'my friend', 'my boss', 'his sister', 'her uncle'. The Pitfall here is this database would quickly get too complicated for unsophisticated users to query and understand and it would get slow as more and more data was accumulated.

Xequence-- The pitfalls in relational database design is that you must learn the system. This process of 'learning the system' will take some time. Another pitfall is that everything must have referential integrity. Not an easy task to think about. The last pitfall in a relational database design is the length of time it requires to build stored procedures and triggers. These values cannot insert null values into a [does not allow null] field that is relational to a foreign key table with more cannot insert nulls that have constraints if the values goes below 0 to email a man in Nantucket that his gridview errored out on line index 4 with his foreign key constraint. *breathe* It gets better..

Information Retrieval (IR) refers to the human-computer interaction (HCI) that happens when we use a machine to search a body of information for information objects (content) that match our search query. Depending on the programmed sophistication of the machine, a person's query is matched against a set of documents to find a subset of 'relevant' documents.

The programmed sophistication of the machine determines its efficiency in extraction or pulling out of 'relevant' content from large volumes of texts. For example, the machine's natural language processing, i.e. it's ability to 'understand' a person's information retrieval process, entails information extraction (IE). IE refers to the machine's ability to automatically extract structured information. IE of structured information relies on this basic content management principle: "Content must be in context to have value". Contextualised content is ontologically categorized and semantically well-defined data.

The technical term is 'justification'. Text can be left or right justified, or both. Left-justified text aligns all the first letters of each line neatly under each other at the left margin. Right-justified does the same but with the lastletter on each line. When text is justified at both ends, the text between the first and last words on each line is spaced evenly - as you would see in a newspaper columns.

Data in the database is very easy to handle. To organize data in database in ascending or descending order we can use group by command.

You can use a template and customize it to fit your personal hotel management system, or you can do one from scratch. There is no wrong or right answer.

Continuous monitoring is important to an HACCP system because of potential food risks during the production process. If something goes wrong, it is important to catch it immediately before the product is beyond repair.

Criminal records are not encoded in passports, nor would you be asked about your records under normal circumstances. However, anyone who has access to the appropriate database that you are registered under would be able to match you passport to that record in the database. A foreign country would probably not know about the traffic ticket you got last week, but they will know about that Interpol Red Notice they put out for you.
