All of my previous databases were predicated on the idea that the record is not created until it is 'entered'. A Ninox record is entered when it is created.

- organise data into information (needs to be done carefully otherwise data becomes meaningless, uses data dictionaries)
- analysing information to give knowledge (access to information purpose of system, analysing done by tables, queries and reports, decisions based on this information)
Organisation of Data[edit]
Data must be organised before it can be analysed by the information system. This must be done carefully, though, or the resulting information will be meaningless. This may require sorting, summarising or classifying. Data is organised using structures such as data dictionaries.

Analyses of Knowledge[edit]
Idatabase 4 4 – organize all your information and database. Access to information and the resulting knowledge is the purpose of an information system. For people to gain knowledge the information must be analysed. Information systems provide a range of tools for analysis of data such as tables, queries and reports.

Types and Purposes of Information Systems[edit]
- TRANSACTION PROCESSING SYSTEMS (TPSs)- collect, store, modify and retrieve the daily transactions of an organisation e.g. a point-of-sale terminal. There are two types of transaction processing:
- BATCH PROCCESSING collects the transaction data into a group and processes it later and is currently used where the data is in paper form such as cheques. This type has a time delay.
- REAL-TIME PROCESSING works where each transaction is immediately processed providing instant confirmation but it does require access to an online database.
- DECISION SUPPORT SYSTEMS (DSS)- assist people to make decisions by providing information, models and analysis tools. They can be used on a daily basis or when an organisation has to react to something unexpected or make changes. Expert systems are a type of DSS.
- EXPERT SYSTEMS- provide information and solve problems that would otherwise require a person experienced in that field (an expert). They are useful in diagnosing, monitoring, selecting, designing, predicting and training. An expert system asks users a set of questions and compares answers to a knowledge base, which is a set of general facts and if-then rules supplied by an expert. It must then reason to attain a solution. These are not always correct and the choice is up to the user.
- MANGEMENT INFORMATION SYSTEMS (MISs)- provide information for the organisation's managers. An MIS presents basic facts about the performance of the organisation e.g. a budget or report. The awareness of how performance is measured provides motivation for workers and helps make decisions. A special type is called the Executive Information System (EIS) which is designed for the information needs of senior managers and provides strategic information.
- OFFICE AUTOMATION SYSTEMS- provide people with effective ways to complete administrative tasks in an organisation. They use software tools such as word processors, databases etc. and also use communication technology.
- A GEOGRAPHIC INFORMATION SYSTEM (GIS), geographical information science, or geospatial information studies is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographically referenced data.[1] In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology.,
- DATABASE INFORMATION SYSTEMS (DIS)- Most information systems (IS) store data in a database. Databases are accessed by a Database Management System (DBMS). A DBMS is a software package that allow users to manage data. SOme examples include; MS Access, FileMaker Pro, MySQL.
Database Information Systems[edit]
Examples[edit]

Information systems that use a database are called database information systems. Databases are accessed by a database management system (DBMS) which has no data in it but is a software package that allows the user to enter maintain and provide access to a database. The user can choose which data is required and how to display it in a meaningful way. The term database is often used instead of DBMS.
Organisation Methods[edit]
Organising is the process of arranging, representing and formatting data. A database is an organised collection of data.
Non-Computer Methods[edit]

A database is simply a place to organise and store data so that it can be retrieved later for a particular purpose. A telephone book is a non-computer database that organises data alphabetically according to a person's family name. Searching for the person's name retrieves their phone number. A paper filing system is a non-computer database. It involves paper, folders and filing cabinets to store data in an organised way. Searching the folders in the filing cabinet retrieves a single piece of paper. Non-computer databases are often the best way to organise data. It is convenient to obtain information from a book or access it from a filing cabinet. People can easily and inexpensively organise data using a non-computer Keepassxc 2 5 15.
