Lecture 5- Integrating information systems

Systems interface- A between information . The interface is likely to consist of &

One systems interface design principle is . The interface should not be

Another systems interface design principle is . If there are any protocols for the interface to be designed, these should be

Third systems interface design principle is . The interface should include some . For example, a check of the of entries sent or verification from one system to that the received data has been

Fourth systems interface design principle is . A log of all data across the interface needs to be , as well as logs of when data was

Fifth systems interface design principle is provide an . An API as relevant to a systems interface is a which describes how a certain piece of software communicates with another

One type of control which should be considered for any system interface is . The details of the interface should be & any protocols adopted should be

Another type of control which should be considered for any system interface is . A systems interface should be to provide a to verify that the data has been . Also, a log of all the events related to the interface should be kept

Third type of control which should be considered for any system interface is . There may be considerations about to a systems interface &/ or

Customer relationship management (CRM)- A approach which aims to , & to the needs of & customers

Two advantages of systems integration are information in an organisation & more business

Three issues with lack of systems integration are possible information from systems, needed by staff to enter & as data needs to be in several systems

Systems integration is important because it ensures function’s is shared & with other departments & data silos

Information systems could be integrated through ( between pieces of ). It can be or protocol, what data is & detect . The communications medium is most likely over or

Internal systems interface- Where or different information within organisation are i.e.

External systems interface- Where or different information in organisations are . Typically an organisation has or control over systems or data of organisations

Application Programming Interface (API)- which describes how piece of communicates with another. It can be considered as of

Systems interfaces are supported by underlying software, software & by . Exact configuration of hardware & software for any particular systems interface will . However, nowadays systems interface will involve use of

Customer Relationship Management (CRM)- Process by which are & . From systems view this includes: & . Also, it assists in managing of business which is of interest to

Supply Chain Management (SCM)- management of activities to maximise & sustain . It aims to forge with . It is about both & flows so all involved parties are

Degree of integration between organisation & suppliers depend on factors such as: of relationship, level of , (longer term relationship) & level of (how much of upstream supply chain is owned by organisation)

Two main options in how accounting software & banks can integrate are: & . SAP offers bank management application, which combines with its package

According to Davenport & Harris (2007), data analytics is ‘ use of data, & analysis, & models, & management to drive & ’. According to Davenport (2012), element of data analytics is important

Enterprise systems allow users to data in & ( data refers to which is broken down into several such as , or ) ways. Such data may be stored in several within software system (often archived in )

Data warehouse- data which is sourced from organisational systems & is stored of operation data. It’s used for & , rather than purposes

Online analytical processing (OLAP)- tool which allows users to & historical data, typically within which is separate from data

Online transaction processing (OLTP)- Refers to how is structured to operational data. OLTP are structured to optimise &

Issues with systems integration include: (if business is using particular system that isn’t connected to other systems, company might need to in other to enable such ), & & standards (sometimes information or processing needs of organisation cannot be )

Benefits of systems integration include: greater , costs through more business processes, improves in areas such as JIT control/working capital management & external data sources may
